How do you create a field in an LF that's the date portion of a timestamp field in the PF? I had already thought of that also, but I couldn't find any keyword to do that. And simply doing a RENAME() with datatype 'L' is not allowed. And you were right about iSeries Nav: it gave me the exact same info as debug.

Another option is to use the SQL analyzer in Ops Navigator to analyze your statement. If you have used debug I don't think this will give any different information. Rick -----Original Message----- From: rpg400-l-bounces@xxxxxxxxxxxx [mailto:rpg400-l-bounces@xxxxxxxxxxxx]On Behalf Of Peter Colpaert Sent: Wednesday, August 04, 2004 3:05 AM To: RPG400-L@xxxxxxxxxxxx Subject: Improve SQLRPGLE performance Hi group, I made an inquiry SQLRPGLE program where I have to do a count of records in a file, whereby one of the group-by fields is the date portion of a timestamp field. The data is presented in a panelgroup application. The performance, when running in production over a 600.000-record file, is very VERY bad. When I debug the program, it says that arrival sequence is used to build the access path. Is there a way to improve the performance, such as by creating an index that has only the date portion of the timestamp field? Thanks in advance.
