i"m using a local sql and i would like to know , if i have a big database (data records ) and i wish to run a query , the all purpose of the query is just to recive from the sql empty dataset (that is combination of the query tables fields ! ) so the query have to be very short on .open (quick) even when there are large data .
(the sql result should be an empty table constructed from the fields in the select query)
i try to use several ways including sql false condition but its look like every time the the sql is running he always scan all the data record ....
can u help me ?
