Part_0. DataBase SQL test/demos

0A1. download demo files from UV Software

SQLdemo documents downloading & testing 3 databases (MySQL,Oracle,& DB2). UV Software provides various test files & COBOL programs that you can download from the website in case you do not have the Vancouver Utilities installed.

Part 0 documents downloading the test files & COBOL programs that will be used in later parts. The test files are provided in a zip file. Download from:


 http://www.uvsoftware.ca/sqldemofiles.zip
 ===========================================

We suggest downloading into a temp subdir & then copying the desired files to the appropriate subdir for your testing. We call the temp subdir 'tmp2'.

We recommend setting up separate homedirs to test MySQL, Oracle,& DB2. You could setup subdirs & store the files in your home dir if you prefer.

If you setup separate homedirs, it might look like this:

 /home/mysql2     <-- homedir for MySQL test files
 :-----cbls         - COBOL programs
 :-----cpys         - copybooks
 :-----ctl          - control files (COBOL directives)
 :-----dat1         - test data files for COBOL programs, etc
 :-----sf           - script files
 :-----src          - C source programs
 :-----tmp2         - unzip downloaded files & copy files to subdirs above
 :     :-----sqldemofiles.zip
 :     :-----cbls
 :     :-----cpys
 :     :-----ctl
 :     :-----dat1
 :     :-----sf
 :     :-----src
 /home/demo1                   <-- homedir for Oracle test files
 :-----cbls
 :-----... same as above
 :-----tmp2
 :     :-----... same as above
 /home/db2demo1                <-- homedir for DB2 test files
 :-----cbls
 :-----... same as above
 :-----tmp2
 :     :-----... same as above

Please see the downloaded tmp2 files listed on the next page.

1A1. MySQL Install & SQL Tutorial

Introduction to SQL demos & tutorials

This 'SQLdemo' gives you the step by step procedures to download the MySQL software from www.mysql.com, and setup a testing directory with demo files that you can download from www.uvsoftware.ca.

The test files from UV Software are much more realistic than the 'pet' table used in the MySQL reference manual tutorial. 'cust1.txt' & 'sales1.txt' are "delimited","text","files" for loading database tables 'ar.cust1' & 'ar.sales1'.

The UV Software tutorial then guides you thru the various SQL commands (CREATE tables, LOAD tables, SELECT from, etc). Since our demo tables have a common customer number field, you can perform a 'JOIN' to select sales1 items matching the customers in the cust1 table.

You do NOT need the Vancouver Utilities software package to perform the tutorials in Part 1. In Part_9, I will demonstrate how the 'uvcopy' utility can help any SQL site create the "delimited","files" required to load SQL database tables.

Preparation to Download/Install MySQL

I will describe the procedures I used to download & install MySQL 5.0 on my Red Hat Enterprise Linux 5.1 (running on 64 bit AMD Opteron HP XW9400). You must of course select the download files appropriate to your O/S & hardware.

I setup user 'mysql2' to hold the various subdirs & files I would require for the project. I used userid 'mysql2' (homedir /home/mysql2) to avoid any confusion with user 'mysql' automatically setup by MySQL install.

Please see http://www.uvsoftware.ca/admjobs.htm#1D2 for the root commands 'adduser' & 'passwd'. I installed the profile recommended for the Vancouver Utilities. You do NOT need the Vancouver Utilities for the SQL demos in Part 1. My only use in Part 1 was for the laser printing scripts, such as 'uvlp12'. If interested you can see it listed at http://www.uvsoftware.ca/uvlist.htm#E1

Download MySQL from www.mysql.com

Use the web browser to download the following files. Store them in /home/mysql2/download & /home/mysql2/doc (see subdirs illustrated above).

Download the 'rpm' files from http://dev.mysql.com/download/5.0.html.

Download documentation from http://downloads.mysql.com/docs/refman-5.1-en.pdf

As of November 2008, the software available was 5.0, but we downloaded the 5.1 reference manual in case of later upgrade (& not much different).

The reference manual is over 2000 pages. I found most of what I needed in the first 200 (install & tutorial) and 1900-2000 (C-API). I printed on my Lexmark T542 (35 ppm Duplex).

1B3. MySQL Install & SQL Tutorial

Better Ways to Load Tables

As you can see above, the 'INSERT' command to load tables would be very laborious. It would be faster to edit the table offline & then 'load' the table in mysql. Of course the table data may be generated automatically by various application programs (COBOL, internet, etc).


 #1. Login as mysql2 --> /home/mysql2
     ================================

 #2. vi dat1/pet.txt   <-- edit the table offline
     ===============     - I prefer the '|' pipe delimiter (vs invisible tab)
      Fluffy|Harold|cat|f|1993-02-04||
      Claws|Gwen|cat|m|1994-03-17||
      Buffy|Harold|dog|f|1989-05-13||
      Fang|Benny|dog|m|1990-08-27||
      Bowser|Diane|dog|m|1979-08-31|1995-07-29|
      Chirpy|Gwen|bird|f|1989-09-11||
      Whistler|Gwen|bird||1997-12-09||
      Slim|Benny|snake|m|1996-04-29||

 #3. mysql -pmysql200  <-- start the mysql 'client' program
     ================    - do not need '-u mysql2' if unix login is 'mysql2'

 #4. use menagerie;
     ==============

 #5. load data infile 'dat1/pet.txt' into table pet
     ==============================================
               fields terminated by '|';
               =========================

Batch Alternative

Alternatively we could use the batch command 'mysqlimport' to load the table from our unix/linux prompt without running under the mysql client.


 #1. Login as mysql2 --> /home/mysql2
     ================================

 #2. mysqlimport -pmysql200 --local menagerie dat1/pet.txt
     =====================================================
Note
  • see the 'mysqlimport' Command on page 4.5.5 of the MySQL 5.1 refman.

These files were originally designed on a mainframe as fixed-length records.

The Vancouver Utilities include 'uvcopy jobs' that make it easy to convert fixed-length records to "delimited","fields", for loading into SQL tables. See the details in 'Part_9'.

The test/demo (cust1.txt & sales1.txt, listed above) are provided on the web site in zip file 'sqldemofiles.zip'

Please see Part_0 for the instructions to download, unzip,& copy to /home/mysql2/dat1/...

subdirs/files used for Tutorial (& later C-API demo)

 /home/mysql2
 :-----bin
 :     :-----sqlcust1      <-- executables for demo programs

We only need the dat1/... files for the Tutorial here in Part 1, but I am also showing other subdirs that we will use in Part_7 to demo the MySQL C-API.

When we 'LOAD DATA INTO' tables, MySQL will store them in /var/lib/mysql/... You do not have to know where they are, but in case you are wondering:


 /var/lib/mysql

SQL table 'JOIN's

Since our demo tables have a common field (custno) we can 'JOIN' the tables, selecting sales items from the sales1 table for each customer in the cust1 table. There is no 'JOIN' command, 'JOIN' is simply a term used to describe 'SELECT's from 2 tables with matches specified via a 'WHERE' clause.


 #10. SELECT cust1.name, sales1.invoice, sales1.product, sales1.amount
      ================================================================
            FROM cust1, sales1 WHERE cust1.custno = sales1.custno

'BATCH files' to CREATE tables

Since 'create table' commands can be very long, is a good idea to set up a 'batch file' to create & recreate when necessary.

createcust1b - BATCH file to create & load cust1 table

 # createcust1b - 'Batch file' to create SQL database table 'cust1'
 #              - by Owen Townsend, UV Software, Nov 07/2008
 #              - see www.uvsoftware.ca/sqldemo.htm#1D1
 #
 # We will illustrate 3 ways to use this 'SQL BATCH file' assuming:
 # - logged in as unix/linux userid 'mysql2' & mysql password 'mysql200'
 # - in homedir /home/mysql2 with subdirs:
 #   /home/mysql2/sf/createcust1b     <-- this batch file
 #   /home/mysql2/dat1/cust1.txt      <-- "delimited","data","file"
 #   /home/mysql2/sf/createcust1      <-- shell script to run batch file
 #
 ##1. If you are running the MySQL client (program 'mysql')
 #
 # mysql> source sf/createcust1b      <-- use 'source' to run batch file
 #        ======================
 #
 ##2. If you wish to run from the unix/linux shell prompt:
 #
 # shell> mysql -pmysql200 <sf/createcust1b <-- run mysql with redirected input
 #        =================================     from the batch file
 #
 ##3. Run a shell script calling the batch file
 #
 # shell> createcust1 sf/createcust1b  <-- run shell script calling batch file
 #        ===========================    - significant code same as #2
 #
 ##4. You could use 'mysqlimport' to load the table (vs using this batch file)
 #    But the table would have to have already been CREATEd
 #
 # shell> mysqlimport -pmysql200 --local ar dat1/cust1.txt
 #        ================================================
 #
 # MySQL BATCH file commands to create ar.cust1 table:
 #
 drop table if exists ar.cust1;
 #=============================
 create table ar.cust1 (custno numeric(6) primary key, name char(22),
                        adrs char(22), city char(16), prov char(2));
 #=====================================================================
 load data local infile 'dat1/cust1.txt' into table ar.cust1
                 fields terminated by ',' optionally enclosed by '"';
 #===================================================================
 select * from ar.cust1;  # display table contents as confirmation
 #======================

1D2. BATCH files for MySQL

The 'batch file' (listed above) documented 3 ways to use it. Method #3 is to write a shell scripts to call the batch file, which saves you from having to run the MySQL 'client' program interactively (could run by cron).

createsales1b - BATCH file to create & load sales1 table

 # createsales1b - 'Batch file' to create SQL database table 'sales1'
 #               - by Owen Townsend, UV Software, Nov 07/2008
 #               - see www.uvsoftware.ca/sqldemo.htm#1D1
 #
 # We will illustrate 3 ways to use this 'SQL BATCH file' assuming:
 # - logged in as unix/linux userid 'mysql2' & mysql password 'mysql200'
 # - in homedir /home/mysql2 with subdirs:
 #   /home/mysql2/sf/createsales1b    <-- this batch file
 #   /home/mysql2/dat1/sales1.txt  <-- "delimited","data","file"
 #   /home/mysql2/sf/createcuast1     <-- shell script to run batch file
 #
 ##1. If you are running the MySQL client (program 'mysql')
 #
 # mysql> source sf/createsales1b     <-- use 'source' to run batch file
 #        =======================
 #
 ##2. If you wish to run from the unix/linux shell prompt:
 #
 # shell> mysql -pmysql200 <sf/createsales1b <-- run mysql with redirected input
 #        ==================================     from the batch file
 #
 ##3. Run a shell script calling the batch file
 #
 # shell> createsales1 sf/createsales1b  <-- run shell script calling batch file
 #        =============================    - significant code same as #2
 #
 ##4. You could use 'mysqlimport' to load the table (vs using this batch file)
 #    But the table would have to have already been CREATEd
 #
 # shell> mysqlimport -pmysql200 --local ar dat1/sales1.txt
 #        =================================================
 #
 # MySQL BATCH file commands to create ar.sales1 table:
 #
 drop table if exists ar.sales1;
 #==============================
 create table ar.sales1 (custno numeric(6), slm numeric(2), invdate date,
                          invoice char(8), product char(6), qty numeric(6),
                                   price numeric(7,2), amount numeric(9,2));
 #==========================================================================
 load data local infile 'dat1/sales1.txt' into table ar.sales1
           fields terminated by ',' optionally enclosed by '"';
 #=============================================================
 select * from ar.sales1;  # display table as confirmation

1E1. SQL Tutorial using UV Software "demo","files"

File Naming Conventions

We have appended a '1' on the end of our filenames ('cust1', 'sales1', etc). This provides several long lasting advantages thru out the life of our applications:

  1. It makes our file & table names 'unique' & avoids confusion with other similar names.

  2. We can reliably use 'grep' & 'find' to search for all instances of a desired file/table name in all our directories.

  3. We can use 'vi' to '/' search for all instances of a desired file/table name when editing our scripts & programs.

  4. It makes it easy to create names for related files/tables. 'customer2' or 'sales2' might be a variant, save, or backup copy. Or we might use 'cust1a', 'sales1a', etc.

COBOL OpenESQL to MySQL via ODBC

Part 2 will demonstrate using OpenESQL & 'ODBC' to access MySQL DataBases to process 'EXEC SQL' statements embedded in Micro Focus COBOL programs.

Part_4 will demonstrate how to access Oracle Databases using 'PROCOBOL' and 'ORACLEOCI', which are proprietary. In theory OpenESQL & ODBC should be able to access any RDBMS conforming to the Open standards.

I had some initial problems getting COBOL OpenESQL to work with ODBC (see details on page '2G2').

I did have interactive acccess to ODBC working. I could use 'isql' to execute manual SQL queries on MySQL tables, so I think it was only the COBOL access that was not working.

Perhaps the COBOL problem is a 32bit/64bit conflict, since Micro Focus say their current OpenESQL version 5.1 is 32 bit, but I am running on 64 bit AMD Opteron and the only drivers I could find on MySQL's website (for my machine) are 64 bit.

I have documented my attempts & solutions on page '2G2'.

You need to understand it before you can setup ODBC for COBOL OpenESQL access to MySQL DataBases. I recommend you print out & study the MySQL ODBC install guide 'connector-odbc-en.pdf'. The 3 most important items are:

  1. ODBC 'Driver Manager' - downloaded/installed from unixODBC.org
  1. ODBC 'Driver' - downloaded/installed from MySQL (mysql-connector-odbc...)
  1. odbcinst.ini & odbc.ini - DSN configuration files (you must edit). Our examples are shown further below.

2F1. COBOL OpenESQL to MySQL via ODBC

'isql' to test ODBC setup

Before we attempt to execute a COBOL program to access MySQL via ODBC, we will test our ODBC setup using 'isql'.

'isql' allows us to enter SQL queries via ODBC, similar to the 'mysql' utility that allows us direct access to the MySQL databases.


 #1. Login mysql2  --> /home/mysql2
     ============

 #2. isql       <-- omit arguments to display 'help' screen
     ====

      isql DSN [UID] [PWD] [options]   <-- command format from help screen
      ==============================
      - 'DSN' (Data Source Name) must match the DSN coded in odbc.ini
      - see [myodbc351] on 1st non#comment line in odbc.ini on page '2E2'

 #3. isql myodbc351    <-- do not need to code UID & PWD
     ==============        since they are specified in odbc.ini
                         - isql displays following & waits for your command:
      +---------------------------------------+
      | Connected!                            |
      |                                       |
      | sql-statement                         |
      | help [tablename]                      |
      | quit                                  |
      +---------------------------------------+

 #4. SQL> select * from cust1;  <-- 'cust1' table created & loaded on page '1C3'
          ====================
 +--------+----------------------+--------------------+----------------+-----+

2G2. MySQL/ODBC COBOL test/demo

setup subdirs & load test files for COBOL demo


 #1. Login mysql2 --> /home/mysql2
     ============

 #2. mkdir cbls cblst cblx cpys ctl dat1 tmp tmp2
     ============================================
     - make subdirs to hold demo files

 #3a. Download www.uvsoftware.ca/sqldemofiles.zip into tmp2/...
 #3b. cd tmp2
 #3c. unzip sqldemofiles.zip
 #3d. cd ..

 #4a. cp tmp2/cbls/sqlmyo* cbls        <-- COBOL programs for MySQL demo

 #7. cp tmp2/dat1/* dat1               <-- test data files to load tables

alternative if Vancouver Utilities installed

If you have Vancouver Utilities installed, you could copy directly from the uvadm/... subdirs to your /home/mysql2/... subdirs:


 #4a. cp /home/uvadm/cobol/cbls/sqlmyo* cbls   <-- COBOL programs
 #4b. cp /home/uvadm/cobol/cbls/testcon1.cbl cbls

 #5a. cp /home/uvadm/cobol/cpys/cust1.cpy      <-- COBOL copybooks
 #5b. cp /home/uvadm/cobol/cpys/sqlca.cpy

 #6.  cp /home/uvadm/ctl/cobdirectives ctl     <-- COBOL Directives for compile

 #7.  cp /home/uvadm/dat1/cust1* dat1          <-- test data files
Note
  • 'sqlca.cob' is the DB2 Communication Area for status & error msgs
  • I copied from DB2 libraries & changed extension to agree with programs
  • you could copy directly from the DB2 library as follows

 #5b. cp $DB2DIR/include/cobol_mf/sqlca.cob cpys/sqlca.cpy

2H1. COBOL OpenESQL to MySQL via ODBC

COBOL Directives for OpenESQL ODBC to MySQL DB

Before compiling the COBOL programs you must activate the database option for MySQL/ODBC. You can see the entire ctl/cobdirectives file listed on page '4T1' but here are the database options (lines 22-32).

 #                       ** Database Directives **
 #  ---------- uncomment 1 of the following & modify if required ----------
 # -C SQL(targetdb==ORACLEOCI)
 # -C "DB2(init==prot db==ar)"
 -C SQL(dbman==ODBC)
 # -C "preprocess(cobsql) cobsqltype==ORACLE8 end-c comp5==yes endp"
 #
 #  Use "preprocess(cobsql) ... to invoke ORACLE PRO*COBOL automatically
 #  Better than running procobol separately prior to compile
 #  animation then shows EXEC SQL stmts (vs many generated lines)
 #  (NO directive required if calling ProCOBOL separately before compiler)
 #
 #  OpenESQL targetdb= alternatives to above "preprocess(cobsql) ..."
 #  could be DB2,INFORMIX,MSQLSERVER,SYBASE (not MySQL)
Note
  • the directive for MySQL/ODBC is uncommented/active above
  • But the downloaded ctl/cobdirectives file may have other options active

2X1. COBOL OpenESQL to MySQL via ODBC

COBOL/OPenESQL/ODBC problems NOW fixed

I was trying to use Micro Focus COBOL OpenESQL and ODBC to access MySQL RDBMS, and had some initial problems, which have been fixed as described here.

  1. I changed the COBOL DIRECTIVES (listed on page '4T1') from '-C SQL(targetdb==ORACLEOCI)' to '-C SQL(dbman==ODBC)'

  2. I recompiled the cobol demo programs (sqlmyo1.cbl & sqlmyo2.cbl) listed on page '5U1'.

  3. My COBOL program connect stmnt gave the following error: --> error detected: Can't open lib '/usr/lib64/libmyodbc3.so' <--

  4. I proved that 'isql' can use my ODBC setup to access MySQL database See my 'isql' test at http://www.uvsoftware.ca/sqldemo.htm#2F1.

  5. Could problem be a 32bit/64bit conflict between the 32 bit COBOL OpenESQL components & the 64 bit driver ?

  6. I downloaded 'mysql-connector-odbc-3.51.27-linux-x86_32bit.tar.gz' & copied 32 bit drivers to /usr/local/lib32/... (see page '2D1')

  7. Also had to re-configure & re-make the 'Driver Manager' (www.unixODBC.org) for 32 bits (see page '2C1').

  8. Then COBOL connect gave "cant connect thru /tmp/mysql.sock"

 #9. So I changed the odbc.ini file (see page '2E2')
      SOCKET = /var/lib/mysql/mysql.sock   #<-- original odbc.ini coding
      SOCKET = /tmp/mysql.sock             #<-- tried this to fix error
  1. But that did not work. After Google searches etc I realized COBOL OpenESQL is using /tmp/mysql.sock, but MySQL is using /var/lib/mysql/mysql.sock.

  2. So I set /etc/my.cnf (MySQL system configuration file - see page '2E3'), so MySQL would use /tmp/mysql.sock (to match COBOL OpenESQL).

  3. It finally worked !!! Hurah !!!

3A1. Oracle Database SQL test/demo

preparation to install Oracle

Here are the procedures I used to download & install Oracle 11g database server & client. My main intention was to test PRO*COBOL.

The first task was to setup a unix/linux user 'oracle' with group 'oinstall' as required by Oracle install. Mount point /h22 had 35 gig available & 20 gig was used after install server & client (& setup 1 demo user & 1 table).


 #1. Login root
     ==========

 #2. mkdir /h22/oracle   <-- make homedir for oracle user (ORACLE_BASE)
     =================    --> export ORACLE_BASE=/home/oracle <-- in profiles

 #3. adduser -m -g oinstall -d /h22/oracle oracle
     ============================================

 #4. passwd oraclepw     <-- set password
     ===============

 #5. setup profiles for Oracle. See suggested profiles at
     http://www.uvsoftware.ca/admjobs.htm#Part_1

 #5a. vi /home/uvadm/env/common_profile  <-- add ORACLE OWNER,DID,BASE,& HOME
      =================================      & PATH to bin, etc
 #5b. vi /home/uvadm/env/stub_profile    <-- will be copied to oracle homedir
      =================================

 #5c. cp -p /home/uvadm/env/stub_profile /home/oracle/.bash_profile
      =============================================================

extracts from profile re ORACLE

      export ORACLE_OWNER=oracle
      export ORACLE_SID=demo1
      export ORACLE_BASE=/h22/oracle
      export ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_2 #<-- unset for install
      export PATH=$PATH:$ORACLE_HOME/bin
      export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME/lib32
      alias cdoh='cd $ORACLE_HOME'  # alias for quick cd to $ORACLE_HOME
Note
  • you must NOT define ORACLE_HOME until after server install
  • since the install determines ORACLE_HOME & tells you

generating batch-files to create & load tables

Creating tables manually (as shown above) would be very laborious for files with many fields. UV Software provides uvcopy job 'sqlcreate1' to automatically generate an Oracle batch-file to create the table. The job also generates the SQL*LOADER control file to load the table. See uvcopy job 'sqlcreate1' and script 'sqlcreateA' fully documented in DATAcnv1.htm#Part_4.

generating batch-files to create & load tables

script 'sqlcreatA' is the easy way to generate batch-files to create & load tables from COBOL copybooks. The script runs cobmap1 to create a record layout & then runs 'sqlcreate1' to generate both the table-create & table-load batch files from the 'cobmap'.

See the demo copybook/map 'cust1' on the previous page. Here is the 'sqlcreateA' command followed by the 2 output batch-files to create & load the cust1 table.

generate job to convert Fixed-Field to delimited for table load

Before we can load the SQL table, we must convert the data file from fixed-field to the the pipe|delimited|format expected by SQL LOADER. We can generate a uvcopy job to do this from the COBOL copybook as follows:


 #1. uvcopy cobmap1,fili1=cpys/cust1.cpy,filo1=maps/cust1
     ====================================================
     - convert copybook to 'cobmap' (record layout)

 #2. uvcopy genpipe1,fili1=maps/cust1,filo1=pfp1/cust1
     =================================================
     - convert cobmap to uvcopy job to convert fixed-field to pipe-delimited
      - - - OR use script 'genpipeA' (combines above into 1 short command)

cobdirectives for Oracle

We will demo COBOL access to Oracle using 3 different interfaces as follows:

 4C1. ProCOBOL run separately prior to COBOL compile script mfprocob1
      - requires 'NO' DIRECTIVES
 4D1. ProCOBOL integrated into COBOL compile (using usual script mfcbl1)
      - requires 'preprocess(COBSQL)' directive.
 4E1. OCI interface built in to Micro Focus COBOL
     - requires 'SQL(targetdb==OracleOCI)' directive
 4F1. OpenSQL using ODBC (required for 'targetdb's other than OracleOCI)
      - not yet provided for Oracle (ODBC is used for MySQL in Part_2)

Here are lines 22-32 of the COBOL DIRECTIVES file stored in ctl/cobdirectives. See complete file listed on page '4T1'. You must uncomment the appropriate line before you compile the programs to demo the various interdace methods.

 #                       ** Database Directives **
 #  ---------- uncomment 1 of the following & modify if required ----------
 # -C SQL(targetdb==ORACLEOCI)
 # -C "DB2(init==prot db==ar)"
 # -C SQL(dbman==ODBC)
 # -C "preprocess(cobsql) cobsqltype==ORACLE8 end-c comp5==yes endp"
 #
 #  Use "preprocess(cobsql) ... to invoke ORACLE PRO*COBOL automatically
 #  Better than running procobol separately prior to compile
 #  animation then shows EXEC SQL stmts (vs many generated lines)
 #  (NO directive required if calling ProCOBOL separately before compiler)
 #
 #  OpenESQL targetdb= alternatives to above "preprocess(cobsql) ..."
 #  could be DB2,INFORMIX,MSQLSERVER,SYBASE (not MySQL)
Note
  • all database directives are uncommented/active above for ProCOBOL
  • But check the downloaded ctl/cobdirectives file for other options active

I specify DIRECTIVES to the Micro Focus COBOL compiler using the 'COBOPT' environmental variable specified in the compile script 'mfcbl1' as follows:


 export COBOPT=$cwd/ctl/cobdirectives
 ====================================
 - used if $cwd (Current Working Directory) contains file ./ctl/cobdirectives

 export COBOPT=$UV/ctl/cobdirectives
 ===================================
 - used if $cwd does NOT contain file ./ctl/cobdirectives
 - $UV is /home/uvadm/

See cobdirectives listed on page '4T1' or at http://uvsoftware.ca/mvscobol.htm#4D1

COBSQL - better for Animation

The 'mfprocobol' compile script (used on the previous pages) executed Oracle's procobol precompiler separately & preceding the Micro Focus COBOL compile.

The disadvantage of separate preprocessing & compile is that animation will see all the voluminous code generated by the procobol precompiler.

It is much better to use the Micro Focus 'COBSQL' option which integrates procobol into 1 compile execution. Animation will then show only the original 'EXEC SQL' stmtns & not the voluminous expanded code. COBSQL is invoked by the following COBOL directive:


 -C "preprocess(cobsql) cobsqltype==ORACLE8 end-c comp5==yes endp"

4E1. Oracle/COBOL test/demo

test option SQL(targetdb==ORACLEOCI)

Here is a 3rd way to compile a COBOL program to access an Oracle database. 'OracleOCI' is a Micro Focus interface that uses neither PRO*COBOL nor ODBC. Here is a summary of the data base access methods illustrated in this document:

 4C1. ProCOBOL run separately prior to COBOL compile script mfprocob1
      - requires 'NO' DIRECTIVES
 4D1. ProCOBOL integrated into COBOL compile (using usual script mfcbl1)
      - requires 'preprocess(COBSQL)' directive.
 4E1. OCI interface built in to Micro Focus COBOL
     - requires 'SQL(targetdb==OracleOCI)' directive
 4F1. OpenSQL using ODBC (required for 'targetdb's other than OracleOCI)
      - not yet provided for Oracle (ODBC is used for MySQL in Part_2)

Here are lines 22-32 of the COBOL DIRECTIVES file stored in ctl/cobdirectives. See complete file listed on page '4T1'.

 #                       ** Database Directives **
 #  ---------- uncomment 1 of the following & modify if required ----------
 -C SQL(targetdb==ORACLEOCI)
 # -C "DB2(init==prot db==ar)"
 # -C SQL(dbman==ODBC)
 # -C "preprocess(cobsql) cobsqltype==ORACLE8 end-c comp5==yes endp"
 #
 #  Use "preprocess(cobsql) ... to invoke ORACLE PRO*COBOL automatically
 #  Better than running procobol separately prior to compile
 #  animation then shows EXEC SQL stmts (vs many generated lines)
 #  (NO directive required if calling ProCOBOL separately before compiler)
 #
 #  OpenESQL targetdb= alternatives to above "preprocess(cobsql) ..."
 #  could be DB2,INFORMIX,MSQLSERVER,SYBASE (not MySQL)
Note
  • the 'OracleOCI' line is uncommented/active above
  • But check the downloaded ctl/cobdirectives file for other options active

preparation to install DB2

Here are the procedures I used to download & install DB2 9.5 database server. My main intention was to test COBOL access to DB2 tables.

I decided to install in file system /h23 which had 35 gig available (DB2 required only about 4 gig).

modify profiles for DB2 users

To allow any user to access DB2, we will modify the Vancouver Utility common profiles. After installing Vancouver Utilities, the supplied profiles are found in /home/uvadm/env/... To preserve modified profiles, they should be copied to /home/appsadm/env/... documented at http://www.uvsoftware.ca/admjobs.htm#1B1

We will insert/modify only a few lines in the 'common_profile'. See the full listings begining on pages 1C2 of admjobs.htm.

We need to modify the COBOL directives file to specify "DB2(init==prot db==ar)" vs 'SQL(targetdb==ORACLEOCI)' used in Part_4.

Please see the entire COBOL DIRECTIVES file listed on page '4T1'. Here are lines 22-30 after the changes:

 #                       ** Database Directives **
 #  ---------- uncomment 1 of the following & modify if required ----------
 # -C SQL(targetdb==ORACLEOCI)
 -C "DB2(init==prot db==ar)"
 # -C SQL(dbman==ODBC)
 # -C "preprocess(cobsql) cobsqltype==ORACLE8 end-c comp5==yes endp"
 #
 #  Use "preprocess(cobsql) ... to invoke ORACLE PRO*COBOL automatically
 #  Better than running procobol separately prior to compile
 #  animation then shows EXEC SQL stmts (vs many generated lines)
 #  (NO directive required if calling ProCOBOL separately before compiler)
 #
 #  OpenESQL targetdb= alternatives to above "preprocess(cobsql) ..."
 #  could be DB2,INFORMIX,MSQLSERVER,SYBASE (not MySQL)
Note
  • the directive for DB2 is uncommented/activated above

6A1. Microsoft SQL Server

Introduction

Microsoft SQL Server for Linux was announced in 2016 (test versions available). General Availability in 2017.

After installing we will test interactively using T-SQL commands to create a simple inventory table with a few values & then 'select * from inventory'.

Then we will show SQL scripts to load & unload a customer name & address table. We can generate these scripts automatically from the COBOL copybook using the Vancouver Utilities, but you could enter them with the editor if you do not have the Vancouver Utilities.

Our goal is prove that SQL Server on Linux works with COBOL programs. We show 2 COBOL programs to load & unload tables & you could extract them from this documentation.

We also show how to convert fixed length records to pipe delimited format for input to the COBOL table load program. We use Vancouver Utilities to to do this automatically based on the COBOL copybook, but again, you could extract the pipe delimited file from this documentation

Hopefully this will help you get started with SQL Server on Linux. In particular, you might appreciate our examples of the 'odbc.ini' file and the environmental variables required in our common_profile.

6B5. Microsoft SQL Server

verify ODBC install

You can test the ODBC connection to the database using 'isql'. The 'isql' utility is part of 'unixODBC'. It can execute SQL statements similarily to 'sqlcmd' which is part of Microsoft SQL Server.


 #1. isql -v 'ODBC Driver 13 for SQL Server' sa mssqlSA00
     ====================================================
     - connect to the database via 'isql'
     - displays Connected message & prompts for SQL commands as follows:

Test SQL Server

Here are some simple T-SQL commands you might run to test SQL Server.

  1. Query SQL Server for a list of the databases.
  2. Use Transact SQL to create a database.
  3. Create a a table in the new database.
  4. Populate the table with a few rows of data
  5. Query the table.

Create a database using the SQL Server default settings.


 #1. CREATE DATABASE testdb; GO   <-- create database 'testdb'
     ==========================
Note
  • T-SQL requires the 'GO' command on a separate line
    after the ';' terminating the command
  • BUT, we will show on the same line to save space

 #2. USE testdb; GO        <-- use the database
     ==============

 #3. Create a table in the current database:

 #3a. CREATE TABLE inventory (id INT, name NVARCHAR(50), quantity INT); GO
      ====================================================================

 #4. Insert data into the new table:

 #4a. INSERT INTO inventory VALUES (1, 'banana', 150);
      ================================================
 #4b. INSERT INTO inventory VALUES (2, 'orange', 154);
      ================================================
 #4c. GO

 #5. Select from the table:

 #5b. SELECT * FROM inventory WHERE quantity > 152; GO
      ================================================

Generating SQL scripts to create & load tables

Creating tables manually would be very laborious for files with many fields. UV Software provides uvcopy job 'sqlcreate2' to automatically generate SQL Server scripts to create & load SQL tables from COBOL copybooks.

'sqlcreate2' must be preceded by 'cobmap1' which converts the COBOL copybook to a record-layout (or 'cobmap'). We will demo cobmap1 & sqlcreate2 using COBOL copybook 'cust1.cpy'.

load script requires pipe delimited input

  1. The table load script requires 'pipe delimted' input

  2. 'sqlcreate2' assumes the name of the input file is the same as the name of the copybook (but in a different directory) and generates FROM '/home/sqldemo1/d4pipe/cust1' (as you see in the script above).

  3. The next 2 pages '6K1' & '6K2' will run 'genpipe1' to convert our fixed length test file from d2asc/cust1 to pipe delimited in d4pipe/cust1

  4. Then we can execute our table create & load scripts on page '6L1'

generate job to convert Fixed-Field to delimited for table load

Before we can load the SQL table, we must convert the data file from fixed-field to the pipe|delimited|format expected by SQL LOADER. We can generate a uvcopy job to do this from the COBOL copybook as follows:


 #1. uvcopy cobmap1,fili1=cpys/cust1.cpy,filo1=maps/cust1
     ====================================================
     - convert copybook to 'cobmap' (record layout)

 #2. uvcopy genpipe1,fili1=maps/cust1,filo1=pfp1/cust1
     =================================================
     - convert cobmap to uvcopy job to convert fixed-field to pipe-delimited
      - - - OR use script 'genpipeA' (combines above into 1 short command)

 #2a. genpipeA cust1    <-- script equivalent of above (shorter command)

sqlcmd vs isql

The commands to list the table contents using sqlcmd & isql above were:


 #4. sqlcmd -U sa -P mssqlSA00 -Q "select * from testdb.dbo.cust1"
     =============================================================

 #6. isql -v 'ODBC Driver 13 for SQL Server' sa mssqlSA00
     SQL> select * from cust1
     =====================================================
Note
  • sqlcmd select required the database.schema 'testdb.dbo' to be specified
  • isql did not require the database.schema to be specified explicitly
  • just 'select * from cust1' worked
  • WHY the difference ?

6L3. Microsoft SQL Server

Errors addressing tables

When I first attempted to list the table, using the following command, I got the Error (shown below the command).


 #4. sqlcmd -U sa -P mssqlSA00 -Q "select * from cust1"
     ==================================================

Msg 208, Level 16, State 1, Server uvsoft5, Line 1 Invalid object name 'cust1'.

I then prefixed the table name with 'database.schema' (as shown below) & that worked.


 #4. sqlcmd -U sa -P mssqlSA00 -Q "select * from testdb.dbo.cust1"
     ==============================================================

So it seems the database is defaulting to 'master' & not 'testdb' which is specified in my odbc.ini (see listing on page '6B3'). Anybody know why this is so ?

PROBLEM connecting from COBOL

      OpenESQL Error: Unable to load ODBC Driver/Driver Manager.

      SQL Server error detected: Connection name not found.

I got the above errors when I 1st attempted to execute the COBOL program. Micro Focus COBOL support (which is great) told me 2 possible reasons:

  1. COBOL mode not 64 - and that was the problem. I added 'export COBMODE=64' to the common_profile & the error went away.

  2. LD_LIBRARY_PATH not including the ODBC libraries. I already had this OK, as you can see in the profile additions at the bottom of this page.

Part_8. MySQL uvcopy-API test/demo

Part 8 - Contents


8A1. 'uycopy' - new version of 'uvcopy' to provide DataBase access
- uvcopy/uycopy differences & uycopy requirements
- typ=DBT specifies a DataBase Table

8A2. Environmental-Variables for Host, User,& Password (can put in profile)
- export DBhost1=... DBuser1=... DBpass1=...

8A3. 'uycopy rules' for database/tables vs directory/files

Here are some 'uycopy' sample jobs to load/unload SQL DataBases from/to "delimited","files". This is an interpretive utility, much easier than writing C programs.


8B1. loadsales1 - load sales1.txt "delimited","file" to the 'sales1' table
- see sales1 table created & loaded manually on page '1C3'

8B2. unloadsales1 - unload 'sales1' table to "delimited","file" 'sales1.txt'
- see listing on page '1C1'

8B3. modifysales1 - modify table by copy out to a file or another table
& perform changes as we reload the table, for example:
- increase prices by 10% & recalculate extended amount

8B4. loadsalesE - similar to loadsales1, but input is original EBCDIC file
- converts Fixed-Field to "delimited", in same job as load
- saves having to delimit in separate job, see page '9A7'
- also translates EBCDIC to ASCII, inserts decimal points,
inserts leading separate signs, converts date formats, etc
Note
  • You need the Vancouver Utilities to perform the Part_8 demos.
  • You do NOT need the Vancouver Utilities for Parts 1-5
  • Part_8 presents 2 C programs to demo the C-API to MySQL
  • Part_2 presents 2 COBOL programs to demo the COBOL-API to MySQL/ODBC

compiling 'uycopy' with SQL DataBase libraries

  1. You must download & install MySQL as instructed in Part_1.

 #2. Login as uvadm --> /home/uvadm

 #3. ccmysqlLNX64 uycopy   <-- execute script to compile 'uycopy'
     ===================

See script 'ccmysqlLNX64' listed at http://www.uvsoftware.ca/install.htm#F1

8A1. MySQL uvcopy-API test/demo

'uvcopy' is a powerful data manipulation utility from UV Software. It is especially valuable for handling data files migrated from mainframes because it can handle mainframe features not handled by any unix/linux system utility:

In November 2008, 'uycopy' was created to provide access to SQL DataBase tables. 'uycopy' had to be a separate version (from uvcopy) because it requires the SQL C-API libraries for compilation at sites with an SQL DataBase installed.

uycopy additions for DataBase/Table access

'uycopy' adds file 'typ=DBT' to define a DataBase Table & 3 environmental variables (DBhost1, DBuser1, DBpass1) for connection to the DataBase. Please inspect the loadsales1/unloadsales1 sample jobs listed on the next 2 pages and note the 'fili1/filo1' (Input/Output) declarations:


 fili1=?dat1/sales1.txt,typ=LSTt,rcs=80 <-- Directory/File dat1/sales1.txt
 #=================-===================   - uvcopy provides only Directory/File

 filo1=?ar/sales1,typ=DBT,rcs=2048 <--declare Output DataBase/Table as ar/sales1
 #================================  - only uycopy provides typ=DBT database/table

 fili1=?ar/sales1,typ=DBT,rcs=2048 <-- declare Input DataBase/Table as ar/sales1
 #================================

Input/Output in Delimited format

For Input typ=DBT, a 'get' will convert the database/table 'ROW' to "delimited","field","format" as shown below.


        get    fili1,a0   <-- get next 'ROW' from DATABASE/TABLE ar/sales1
        ===============     - converts to "delimited","format" in area 'a'
                            - from 1st byte 'a0' (displacements 0 relative)
                            - 1st record for our sample data would be:

 130140,21,2004-08-02,"INV11201","HAM001",000010,00012.00,0000120.00
 ===================================================================

For Output typ=DBT, a 'put' will INSERT "delimited","field","format" into the current database/table 'ROW'.


       put    filo1,c0       <-- write a 'ROW' in DATABASE/TABLE ar/sales1
       ===============         - from area 'c' "delimited","format"

Can do any other processing required while loading/unloading database tables. For example, see 'modifysales1' (page '8B3') to increase prices by 10%

8A2. MySQL uycopy-API test/demo

exports for Host, User, Password


 export DBhost1=localhost   <-- host defaults to 'localhost' if not exported
 ========================

 export DBuser1=userid      <-- userid defaults to login user if not exported
 =====================

 export DBpass1=password    <-- will prompt for password if not exported
 =======================

Environmental Variables for host,user,passwd can be in the profile. The profiles supplied by UV Software (see ADMjobs.htm#Part_1) will define these as DBhost1=localhost, DBuser1=mysql2,& DBpass1=mysql200.

There is a similar set of variables (DBhost2,DBuser2,DBpass2) that if undefined will default to the values for DBhost1,DBuser1,DBpass1. These are used for the output database/table (vs the input database/table) in case you wish to copy database tables between different databases & different machines.

uycopy vs uvcopy

Do NOT confuse the 'uycopy' jobs here in Part 8 with the 'uvcopy' jobs in Part_9. The 'uycopy' jobs access the Database/Tables directly via fili/filo 'typ=DBT' (only in uycopy, new as of Nov 2008).

The uvcopy jobs in Part_9 were used prior to uycopy availability & are still useful unconnected from the database. They convert Fixed-Field to "delimited" & vice-versa, prior/after loading/unloading files to/from database tables using SQL commands manually or in scripts.

8A3. MySQL uycopy-API test/demo

uycopy Rules re DataBase Table I/O

  1. 'uycopy' was created from 'uvcopy' in Nov 2008. It is the same as uvcopy, but with access to DataBase Tables via file 'typ=DBT'.

  2. Only sites with MySQL installed can compile uycopy, since it contains references to MySQL libraries.

  3. Database Tables are handled like sequential files. The table 'rows' are handled like sequential file 'records', but in "delimited","field","format".

  4. You define an input table using 'fili1=database/table,typ=DBT,rcs=2048' (vs sequential file 'fili1=directory/file,typ=LST'). For an output table, you would specify 'filo1=database/table,typ=DBT'.

  5. The record size (rcs=2048 here) must be larger than the "delimited","record", that is the input to or output from the table rows.

  6. When output tables are opened, all rows are deleted. uycopy expects you to reload the table from a "delimited","file" or from another table.

  7. Output tables must have been previously created & all fields defined corresponding to the delimited file used to load the table.

  8. Currently there is no update in place. To modify a table, you must copy it out to a "delimited","file" & reload while performing the updates.

  9. When an INPUT table is opened, the database connection is established using environmental variables DBhost1, DBuser1, DBpass1, which might be defined in your profile if usually the same. The defaults are: DBhost1=localhost, DBuser1=$LOGNAME, DBpass=(prompt if undefined).

  10. When an OUTPUT table is opened, the database connection is established using environmental variables DBhost2, DBuser2, DBpass2, which will default to the input host,user,pass if not specified differently.

Part 9 - preparing test files for SQL demos


9A1. Test files for MySQL demos ('cust1' & 'sales1')
- mainframe type files migrated to Unix/Linux/Windows
- Fixed-Field record layout converted to "delimited","format"
  as required for input to SQL databases

9A2. Executing uvcopy jobs to convert to fixed-field to "delimited","format"

9A3. uvcopy job 'delimcust1' to convert 'cust1' to 'cust1.txt'
- inserts "field","delimiters"

9A4. uvcopy job 'delimsales1' to convert 'sales1' to 'sales1.txt'
- inserts "field","delimiters", option for just ','s on numeric fields

9A5. uvcopy job 'undlmsales1' to convert 'sales1.txt' to tmp/sales1.fix
- undelimits, converts "delimited","format" to fixed field format

9A6. Converting Original mainframe EBCDIC sales1 file to ASCII
- converting zoned signs to 'separate sign leading'
- inserting 'decimal points' (vs mainframe assumed/implied)

9A7. uvcopy job 'delimsales0' to convert original EBCDIC to delimited
- translate, reformat, delimit, etc

9A8. Using 'uvhd' to investigate original EBCDIC sales1 file
- can not use Unix/Linux utilities (vi, etc) to investigate EBCDIC files

Notes about Part 9

This info (about creating "delimited","files" from fixed length files) is at the back in Part_9 because not everybody will be interested. You do not need to know this if you just want to use the "delimited","files" to do the SQL tutorials in 'Part_1' & 'Part_3'.

If you are a UV Software customer & have Vancouver Utilities installed, these examples will help you to convert your fixed-length records to "delimited","format" for loading your database tables.

Do NOT confuse the 'uvcopy' jobs in Part_9 with the 'uycopy' jobs in Part_8. The 'uycopy' jobs access the Database/Tables directly via fili/filo typ=DBT.

The uvcopy jobs in Part_9 are used to convert Fixed-Field to "delimited", prior to loading a DB/Table using SQL, OR convert "delimited" to Fixed-Field, after unloading a table with SQL.

test data files for MySQL demos

Test files 'cust1' & 'sales1' are provided in /home/uvadm/dat1/... These are mainframe type files with fixed record layouts & we will need to convert to delimited format before we can load into MySQL database tables.

I have listed the 2 files below, with the 'uvlist' utility & option 'y80' to print a column scale, which makes it easy to determine the record layout.

uvcopy jobs to create "delimited", files

Here are the 'uvcopy jobs' used to create the "delimited", files listed above. 'uvcopy' is an interpretive utility that interprets the 'uvcopy jobs' (or 'parameter files' or 'instruction files'), with no compilation required.

These supplied parameter files (or 'pre-programmed jobs') are provided in /home/uvadm/pf/demo/... which is in the PFPATH searched by the uvcopy utility.

The critical instruction is 'dlm', which converts a series of fixed 'maximum' length fields to the "delimited", format. Op1 'c0(100)' defines the output area, op2 'b0(100)' defines the 1st max lth field, op3 specifies the number of fields, & op4 defines the delimiter.

The preceding instructions reformat the incoming 'actual length' fields to the 'maximum length' fields. We use 100 bytes as the maximum, because that makes it easy to code the 'mvc' instruction addresses.

Here is just the 1st line of the 'sales1.txt' file (all lines on page '9A2').

You can see that the fields with 'ALPHA' characters are surrounded by "double quotes", but the 'NUMERIC' fields are not. This is caused by the 'n1' option on 'dlmn1'. All instructions are 3 characters & anything following the 3rd character is an option.

converting "delimited","format" to Fixed-Fields

This job is listed here in case you are interested in seeing how you could convert "delimited","format" back to Fixed-Field format.

The 'und' instruction converts to a MAXIMUM field length, followed by a series of 'mvc' instructions to create the desired output record layout.

9A6. converting Fixed Fields to Delimited for DB table loads

converting Original EBCDIC sales file

The preceding delimit jobs assumed the data files had already been translated from the mainframe EBCDIC to ASCII files with numeric fields converted from 'zoned signs' to 'separate leading signs' & with decimal points inserted.

Here is the original file. We show it translated to ASCII (so you can read it). Numeric field signs still reflect the mainframe conventions:

      EBCDIC zone + sign is x'C0', + 0123456789 becomes {ABCDEFGHI
      EBCDIC zone - sign is x'D0', - 0123456789 becomes }JKLMNOPQR

original EBCDIC sales1 file dat1/sales1_origE

If you did want to investigate the original EBCDIC file, you can NOT do with 'vi', but you can use 'uvhd'. uvhd is a FREE utility from UV Software for investigating files with non-ASCII data (packed, binary, EBCDIC, etc). You can download uvhd from http://www.uvsoftware.ca/freestuff.htm

uvhd will display the 1st record & prompt for commands to browse, search, etc:

uvhd display is 'vertical hexadecimal'

uvhd displays data in 3 line groups (characters, hex-zones,& hex-digits). We specified option 'a' to translate the character line to ASCII, so we can read it. The actual data is displayed in vertical hexadecimal on the 2nd & 3rd lines (hex-zones & hex-digits).

The 1st byte (displayed as an ASCII 1 on the translated character line) is actually x'F1' zone 'F_' & digit '_1'. The letter 'I' is x'C9' zone C, digit 9.
