Well, yes.  But, since I'm a nice guy, I'll answer your question eventhough it does not relate to Postgres ... if you
promisenot to do itagain!  In the future, send this question to a more appropriate list,such as PSQL-ODBC, where they
discussPaotgres & MS Access.

You are exactly correct.  MS Access 97 does not support sub-queires inthe FROM clause.  THe only sub-queries supported
byAccess 97 aresub-queries in the WHERE clause.
 

All the more reason to use PostgreSQL!
