Thanks Buck! I've been using the DIAGNOSTIC values, but that seems a more sure thing.

But wait, you need a SELECT to do the count, and you can't do it when you open a cursor. I don't think you would run the cursor and then do this count with the same SELECT statement, so how is this?

The SQL cursors I use take a long time. It's probably quicker for the second SELECT, but I don't think that much.

How do I determine the number of records in the cursor I've just opened?
GET DIAGNOSTICS :x = ROW_COUNT returns the number of rows processed--not
what I need here. GET DIAGNOSTICS :x = DB2_NUMBER_ROWS seems to be the
right call but it gives me a nonsense (I think) number (14932) when there
are zero rows. If I have zero rows available, I close the cursor, sleep,
wake up, open the cursor again, and check for available rows.
If I want a count, I do SELECT COUNT(*) INTO...
To me, the diagnostic counts always seemed more like approximations
rather than actionable data.
