Re: SQL Fetch into DS

I have a program that loops through fetching various groups of records... This is within a statement that was called 3 times with different cursors.

The first time through, 4 rows were retrieved.
Second time, 1 row.
Third time, 1 row.

When this ran today, iteration 2 and 3 contained the new row AND the 3 rows leftover from the first iteration.

My question is, do I need to explicitly "clear" the data structure before the SQL Fetch?

Not exactly, but it won't hurt.

I understand that you tried it and got no results; perhaps posting that code will clear this up. Lord knows I myself have put a CLEAR one line too far down...

What I myself do for multi-row FETCHes is to handle undesired SQLSTATEs, and then only use as many rows as got actually returned by checking SQLER3.
