I know this is basic stuff but I just can't figure it out. :oops:

I need to do a sql query & depending on the outcome return an exit code of 1 or 0.

It's to determine which is the principal database in a mirror pair & therefore which database should be backed up by my backup app.
So the backup app runs the batch ... which runs a sqlcmd ... which returns a yes or no.
How do I return this as an exit code to the app.

I know how to output a 0 or 1 to a text file but can't suss how to return an exit code.

Grateful for any help at all!!!

Thanks.

use the exit command
exit /b 0 or exit /b 1

Thanks ... is it possible to test this.

ie.
Batch 1 calls batch 2
Batch 2 runs sql & exits with the 0 or 1
Batch 1 returns something / does something with the exit code.

Sorry if these are totally dumb questions. Appreciate your time.

Thanks for the replies. I don't really understand the last one but I've made progress with your help ...

The final bit I'm stuck on is:
sql query returns 0 or 1
how do I convert this into my exit /b 1 or 0?

if ... but can't suss the syntax. how do i say if ... incoming value from batch 1 ....
