Re: pg_pconnect - ??

<Grin> - yes, I do the indexing and all that good stuff - even
casting the variables on my select statements. But no matter what you
do, it takes time to go through half a million records and add them
up in a certain way (sub totals when a value changes). I made sure
that I have the right indexes and that they are selected, when I do
the 'select'. I'm not new to databases & sql and all that stuff, just
new to PHP. I also don't allow the user to enter SQL statements
directly or let them do dynamic queries where they can specify their
own 'where' or 'order by' or stuff like that.
