DB2 SQL - How can I provide for a variable substitution in my SQL where clause?
Hi All,
I need to be able to substitute two variables in this simple SQL code:
The JCL:
//SETVAR SET SSNODE=DBO1,DBOI=P1,DBOO=D
// TRK=OG1,LOADIR=TEST,
// PARMDIR=OGDBA,
// PDBNAME='OG1DD%1', <<-----Database name
// PTSNAME='OG1SC%' <<-----Tablespace Name
//SYSTSIN DD *
DSN SYSTEM(DBO1) RETRY(3)
RUN PROGRAM(DSNTIAUL) PLAN(DSNTIB81) -
LIB('SYS2.DB2.TEST.RUNLIB.
END
/*
//SYSIN DD *
SELECT '-START DB('||DBNAME||') SPACENAM('||NAME||') ACCESS(UT)' <<<------SQL
FROM SYSIBM.SYSTABLESPACE
WHERE DBNAME LIKE %PDBNAME
AND NAME LIKE %PTSNAME
// PDBNAME='OG1DD%1', <<-----Database name
// PTSNAME='OG1SC%' <<-----Tablespace Name
How can make this work? I am getting errors every which way I try!
Your expert help will be highly appreciated

there is no simple way to do that
you can either write a program that gets those parameters and put them in the sql query and then execute the query or generate the input file for dsntiaul, or you can try to use iebgener to modify the input file for dsntiaiul

Ok, moni_sabag, could you kindly describe in more detail with example of what or how you will go about doing what you have in mind?
Thanks

First, we are do not have many of the avaiable DBMS management toolset available to us so I am not privileged in that regard.
I have several application tracks and the associated databases. I do not want to have to update many many jobs every time a change is made/added/dropped, etc to tablespaces or tables if I want to QUIESCE, or put Tablespaces in utility mode during DB maintenance.
Also, I want to try to use only one Procedure for all my DB2 environments: 6 QA environment and 4 Test environment not to mention my production environments. Each environment has at least 7 applications/database tracks. My good news is that the database and tablespace are identical in almost everyway. By using symbolic substitution method, I can do this easily I believe.
The problem is, and as you so rightfully stated earlier, there is no easy way (or is there?) to get DNSTIAUL to accept parameter substitution the way I have it in the SQL that you saw before.
All I really trying to achieve here is be able to specify a database and/or tablespaces, select all tablespace that I specify and put them in utility mode or return them to read/write at will without doing any hardcoding!.
This SQL works just fine only if I hardcode a database or a tablespace name. I want to substitute to two parameters dynamically.
I hope this help to clarify what I am trying to achieve.
Thanks
