I am cleaning up a old database with a ton of data.
Here is my situation
one table tblcustomer. Has data accountno
another table tblmarketing has field accountno. But no info
the tables have no relationship set up and I need accountno to be updated for all records in tblmarketing for reports to capture for invoicing mktg fees.
i tried a union SQL statement to join tables and got an accurate result for union, but I cannot do a update or append query.
