Select this option to build a Join clause.  A Join clause lets you retrieve and manipulate data from multiple tables in a single select statement.

Pressing OK in the Join dialog box adds the Join clause to the Select Statement.  The SQL Statement window displays the Join clause as part of the current SQL statement.
