Kathy,

OK. So they will get the first cursor back and process each record and call a second cursor - like a double loop?

Or you could return both cursors at the same time and do what I suggested - the second cursor is returning the data as a result of the first cursor.

I'm still having trouble understanding how you want this to work.

no, they want two distinct cursors.... We had two procedures using dates for the parent and the child queries but
the dates can be relied upon. (bad third party package, bad data, bad vendor...)

So as not to break the original UI or have to change code (god forbid developers change their code here) I have to come up with another solution.

Otherwise I agree with you.

Kathy,

Why even return the first cursor? Why not return the second cursor with the results of the first cursor already wrapped in the second?

Does this make sense? What they *really* want is the results from the second cursor. So why not just give it to them with enough items in the select list so they can get the data they want?

what I need to do is return a cursor from one query in a procedure.... no problemo

What I need to do is :

for every ID returned in the first query returned ....use this in the where condition of the child query.

Yes they want two separate cursors returned. so a function is out.

The first query is intensive so I don't want to execute it twice.

This will be executed quite a bit and returns a fair amount of data.

Thanks,

Kathy
