A question regarding an Database query, using VB.net.
I would like to query a database to get the names and telephone numbers from the database using as a reference either an array or a datatable using sql.
Select Names, Telnumbers from My database if ( the name im looking for is in a datatable or array ) (I can create either)
at the moment Im using a loop to search for them but this is so slow I would like to get all the info out at once.
Is this possible? Or is it only possible if the names are in a nother database? And if so how can I for instance access the said data from a Access database when the names are coming from a dbf?
I have done this with 2 dbf's in the same folder quite sucessfully cutting down the search time using loops from 30 minutes to about 60 seconds and would like to do so again in this different scenario. What would be the best way to go?
