Re: Faster HTML Output.

[Michael_Schutte@xxxxxxxxxxxx]

The reason for using the temp table is a pretty big one.    We do not do
logical DDS joins in our shop.  The ordering the user wants is over fields
in multiple files.   So as I stated, I'm creating a temp table, then
creating indexes over that empty temp table, then executing the select into
that temp table.  BTW, the user is wanting to sort the data one of three
ways.

If you can read through a cursor faster than regular I/O please inform me,
cuz as I see it... I still have to loop the same amount of times.

Also, I was always thought, you'd get better execute time when you select
the data you need from large tables into a temp table.
