[AccessD] Update query broke

IN is faster than NOT IN because it doesn't have to search the entire
list every time.

Hi John

Without your SQL I guess you have some joins.
Replace these with .. IN ( .. ) or .. NOT IN ( .. ) constructs.

For very large tables that may too slow. If so, create a temp table with
the selected output, then use this to update the other tables.

That was it.  Now I am getting "updating data in a linked table not
supported by this ISAM".  The linked table is in the BE, and I have
never seen this on before.  Sigh.  I guess I pull the queries into the
BE and do it there.
