Do you often pull your data one stock at a time? If so
have only 1 row per day, if you have more than 1 you'll
need to add additional where clause fields or do a Max, min etc.

If all 2,400 tables have the same 9 columns you could try using a
single table and adding a column for the ticker of the stock and then
add an index to that column to allow quick lookups based on the

I'm just starting with SQLite (from vb.net) and could use some advice.
I have a set of 2400 (could get substantially higher) tables in a single

Each table has 9 columns (all text for now) and some several thousand rows.
So
13 matches
