Re: Stored Procedure Speed/Visual Explain

Thanks Gary...I'll do that next. I think some/most of the logicals may have
select/omit criteria, and I think that disallows them from consideration.
Right?

Michael,
If nothing from the Advisor, have you at least
checked all Where clauses in your SP for a match
or near match to existing index/LF ?

Subject: Stored Procedure Speed/Visual Explain

Visual Explain/index Advisor woes. I have a stored procedure that calls an
RPG procedure that returns a result set. All is well. But it's slow. So I
take the stored procedure call, put it into Navigator->Run SQL Scripts,
highlight the statement, click Visual Explain, get a chart of objects used
in the query, click Actions->Advisor, and no indexes are suggested. This
query can take a long time to run - 50+ seconds first time, 30+ seconds
after that.

How can I get more information regarding the indexes used or needed?

Thanks!
