How to exit rule when SQL record count is 0
Q: We have an SQL as source job that emails the results of the SQL statement as a file. The problem is that we do not want the results/email sent when there are no records. I see that the variable %QSC contains the record count. How can I use that variable to exit the rule and not email the empty results file?
A: So I guess you have SMTP as Destination?
Please add the following SQL ‘On Destination’ script and try once more:
Begin psExitCode:= 1; // ... add your code here If psQSC = 0 Then psExitCode:= 0; End.
- Feedback customer: Yes, it is a SMTP destination. Based off what you sent below I added the Pascal script with the addition of some logging:
This works as expected and what we want, but it also creates the temp file. Is there a way the temp file can be suppressed? If not, I can add a rule to delete them.

- Reply to customer:
Please try to add
DeleteFile(psFilePath + psFileName);
to the script.
Begin psExitCode:= 1; // ... add your code here If psQSC = 0 Then Begin DeleteFile(psFilePath + psFileName); psExitCode:= 0; End; End.
It seems you are using our Backup option. In your case, we would add the ‘backup’ as a second WIN destination because otherwise you still get the temporary file in your backup folder (instead of using our BACKUP option).
- Feedback customer: That got it! Thanks you for your help. We are all good now and the rule is working as we want it to.
