Rick writes "I am trying to design an ASP page that allows the user to input one or more parameters to search on. When they click on submit, I need to build a SQL statement that reflects their desired choices. The information they can search on, is spread across multiple tables." We'll cover the UNION statement which allows you to join multiple select statements together.

Hi, I am trying to do so with an Access db, and appears to fail.
Is that "adding extra fields in a query" an SQL Server exclusive feature?

If so, how could I retrieve each record's original table in a multiple UNION clause?

I mean:

SELECT name , id FROM table1
SELECT name.....


John - Table1
Peter - Table3
Nicholas - Table2

Thank you
