Toad for Data Analysts does not have a menu entry or button to use ANSI joins as stated in the documentation.
WORKAROUND:
None
STATUS:
Waiting for fix to be released in a future version of Toad for Data Analysts.
This is fixed in beta version 3.0, which can be downloaded at http://tda.inside.quest.com/beta.jspa.
The ANSI button enables for SQL Server 2008, but not 2005.
