Figured it out. just use the "use name_of_db" and you can switch to another DB.
thanks. -----Original Message----- From: Norris, Joseph Sent: Wednesday, September 25, 2002 9:02 AM To: 'Ian Robertson'; Norris, Joseph; 'Peter van der Goes'; 'Thomas R Wyant_III'; [EMAIL PROTECTED]; 'Mysql_List (E-mail)' Subject: RE: Win32::ODBC Question (Oracle) Ian's help worked great. I have one question. How do I specify the DB? I mean in the query analyzer I can select a db from the pulldown box - is there a way to specify the db in the statements below?

I have been accustomed to Mysql with all of its nifty little extensions - like describe. Now I have a project with MSSQL (not because I wanted it - politics). Does any one now how to describe a table structure with standard SQL. Even more important - in Mysql there is the show tables; command which allows you to see the structure of the whole DB. Is there a way to do this in standard SQL?

The Oracle ODBC drivers don't know anything about "DESCRIBE", because it's not a SQL command.
