Access front end, DB2 backend

[Johann]

I have an Access front end that talks to a DB2 backend
via SQL pass-through queries.

I have written a Visual Basic front end in an Access
form. Now I want the VBA to send an SQL pass-through
query to the DB2 back end.

Does anybody know how to tell VBA that the SQL commands
that I have given, should be executed as a pass-through
query to DB2, and not be executed by Access?

Thanks
