Hi Peter.

There's no way to do this, at least that I've come across. I've been faced with similar situations and I have gotten the data I need from the second table, then added the table's fields to the memory-only ADO recordset, then looped through the two recordsets to add the appropriate data.

This requires a design that includes as little data as possible being returned from the data source, of course...

I have also seem folks create temp tables and dump the memory-only rs into the table, and *then* execute a select. And then, of course, clean everything up. Pretty inelegant, but it works.
