Yes, on the same machine. I have everything set to read only, no commits, just doing a simple

Select * from HedgeData Order By TradeDateTime

Then, loop and get fields..

I guess a Stored Proc is possible, but would be very very hard do, as Id have to write tons of UDF stuff.
Im wondering if it would be faster to dump it to a DBF etc and just read the file..

Hello Gordon

Obvious question - is the database on the same machine as the app?

Why no way for stored procedure? or is that challenge for the community ;-)
