RE: SQL Performance Question

Charles,

I ran the SP from iNav and it took a LOT longer. Just about as long as it
takes from the website. So now, what is different in the SP & just the SQL
running?

Debbie

We are running the SQL statements. I will try it the other way and see what
happens.

Debbie,

When you say, "Yet, if we take the SQL and run it in Navigator", what do you
mean?

Are you running the SQL statements from the SP in iNav or are you actually
calling the SP from iNav?

If you're not actually calling the SP, then do so. If the performance of
the SP from iNav is good,
then the problem is outside the System i.

How is the web team calling the SP?

Subject: SQL Performance Question

We have some "SQL" processes that were written by our web development
team.
They were made into stored procedures on the iSeries. When they run for
our
website, they take 15 or 20 seconds, some times more to run. Yet, if we
take the SQL and run it in Navigator, it takes about 450 ms to run.

Any ideas on how to improve the performance of these stored procedures?

I have created the "suggested" indexes and still no improvement.
