Hi,
In a COBOL-DB2 program, I have an existing Multi-fetch Cursor that fetches upto 30 rows from a group of tables (join).
DECLARE ABC CURSOR WITH ROWSET POSITIONING FOR ...
I fetch 30 rows at a time in this program using the cursor.
FETCH NEXT ROWSET FROM ABC FOR 30 ROWS...
I have a requirement where I have to use another cursor within the loop that fetches rows from the above multi-fetch cursor, to retrive some fields from a different row(s) of the same table.
I have taken care of moving the SQLCODEs and SQLERRD(3) values to a working storage so that the new cursor doesn't interfere. But will this new cursor reset the ROWSET pointer when I try to fetch the next set of 30 rows from the multi-fetch cursor?
P.S : The reason why I have to include the new cursor is that I have a specific use case around the new select returning multiple rows. I couldn't use the -811 logic since my program uses "WHENEVER SQLERROR" to force an ABEND.
Any insight would be appreciated. |

Could you please elaborate on this? What makes you to include that within the same cursor and based on what conditions you will fetch the rows here?

Why would that be as they are two different cursors with SELECT and did you try executing it? |
