Optimizing queries

Hi ,

I am a newbie to the world of Postgres, I am currently optimizing
PHP/Postgres applications. My problem is that I have a query that throws
certain rowsets and depending on these values I loop other tables to get the
desired columns. I am using a heavy for-loop for this purpose, within the
for-loop I have further sub-queries, so that for every loop iteration I
execute these sub-queries, I dont see a way to reorganize this structure.
Can somebody suggest a better way.

Thanks
Regards
Sid

Re: Optimizing queries

Are you sure you can't use inner / outer joins or unions to make this one
big query?

If you'll post a bit of your php code and your table design, we might be
able to make some suggestions.
