I have to pull 10% of the data from about 400 tables, and I likely need to do this over and over again. So here's the question -- when I make the flow, is there a way to specify "select top 2500" for the records to pull? This is DB2 and SQL*Server, two separate efforts.

I'd like to be able to specify a preset number of records for copying whenever the flow is run.

This is in I-Way version 8.

John_Edwards,
In WebFOCUS you can always add in a recordlimit for a table request.

WHERE READLIMIT EQ 2500

I am sending this to the Data Migrator group for assistance. This post will be moved to the iWay Forum.

Thank you for participating in the Focal Point Forum.

You can set the STARTAT and STOPAT variables before the data flow runs to limit what goes in your target.

Is there a way to embed that into the routine itself for when I run in batch mode?

This is for a sample of all tables across a very big database, about 350 transforms running one after the other and each pulling about 10% of the total content. I've opted to use the FETCH FIRST 1 ROWS ONLY feature. But this has meant I've had to create custom (though simple) SQL requests for each table. This appears a workable solution.

An example of usage for STARTAT/STOPAT:
EX CMASAP APPDIR=app1,REQ_NAME=req1,STARTAT=0,STOPAT=2

Ah -- I like that. It puts all my tables' selection limits in a single process flow file too.

Thanks for the tip!

Test this carefully, as I believe the stop at is a write limit and not a read limit.
