How to Check for Duplicates?

I have two different tables (Table1 and Table2) that have the same
column in each (Name). Is there an easy way to check for duplicates
between the two tables?
 
Click on the New (Query) toolbar button.

Select the "Duplicates..." query and follow the wizard's instructions.

Write this query and save it:

SELECT [Name]
FROM Table1
UNION ALL SELECT [Name]
FROM Table2;

Now use the query wizard to build a "find duplicates" query. By the way,
Name is a reserved word so you'll avoid bugs by not using it to name columns.
