>What is the best way of combining recordsets together to form one recordset?

Do a join on the desired tables from the backend (with a SQL statement). I know, kind of a trick answer but there is no easy way once you have separate recordsets on the client.

If this is not possible, it is possible to do it on the client side, it can be done by creating a disconnected recordset from scratch and populating row by row. Something like the response you got from Igor Gelin on your thread "Temporary Table".
