Passing result of DB2 TRUNC_TIMESTAMP in JCL steps

Postby Okonita » Thu Mar 27, 2014 3:17 pm

Hi all,
How can I dynamically pass the result of DB2 TRUNC_TIMESTAMP of any kind in my JCL steps?

I am looking to create a JCL stream that will do the following:

Step 1: Run a instream DB2 Param1 = Select TRUNC_TIMESTAMP(CURRENT TIMESTAMP,'MONTH'**) from SYSIBM.SYSDUMMY1;

Step 2: Param2 = Select TRUNC_TIMESTAMP(CURRENT TIMESTAMP + 1 month,'MONTH')- 1 MICROSECOND)** from SYSIBM.SYSDUMMY1;

Step 3: Select count(*) from HLVQUAL.TABLE_NAME where CREATE_TS between Param1 AND Param2

I will highly appreciate any examples, how-tos and other helpful comments to resove my issue.

Thanks everyone

I suspect that you can do all that in the one query in DB2. However, if you need to do it as you have shown then you need to write your output from step 1 and step 2 into a file and read that into step 3 and build your select statement which means that you may need programs for all 3 steps because JCL alone cannot do it.
The problem I have is that people can explain things quickly but I can only comprehend slowly.
