Subject: Re: [sqlite] Direct access of table data
Griggs,
Thanks for the quick reply. I guess I'm just getting greedy since sqlite is so
much faster than our standard databases ("progress").
When you run a query for select * from table, does it literally copy the
contents of the table, or does it just build a structure that points to the
data in the table?

No easy way. The sophistication of database abstraction is the reason you
presumably chose to use sqlite.
Re: "I thought it might perform much [better] without all .."
If you've measured this and the query truly takes too long, you might try
(in order):
1) trying to optimize the query (do you have ideal indexing, for instance?)
2) restructure your data/program
3) use a simple file rather than a database
