Hi Mike, What do you mean by "scroll through". Is this just a query->Next() ? When we read a recordset straight through, I use the following params in the TADOQuery: CursorLocarion = clUseServer CursorType = ctOpenForwardOnly CacheSize = 100 LockType = ltUnspecified With this setup, I can read 1,000,000 rows from an Oracle server across a 100 MBPS LAN in about 20 seconds. Can you provide any additional info? - Arnie "Mike Ruskai" <spammoc.reirracten@begoneynnaht.net> wrote in message news:gunaalargpneevrepbz.h298xv0.pminews@207.105.83.65... > Using BCB6 and ADO (MDAC 2.7) to access data in an Access 2000 database. > > I have found that the Next() function of TADODataSet (or TADOQuery - doesn't > matter) is *extremely* time-consuming. < snip >
