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

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.
