Apologies for giving wrong answer in the past (Answer #4)
You can actually join multiple tables in the lookup.
Here are the steps.
1. Click on Lookup transformation
2. Click on "Skip" button to the right
3. A green Lookup Transformation will apprear without any
ports.
4. Put your query in the SQL Override.
5. Make sure you specify the columns you selected in your
query as ports IN THE SAME ORDER
6. Your lookup is ready
NOTE: When you specify the query make sure you specify
column alises for each column.... else you will get invalid
lookup error during run time.
Good Luck!

Answer / murali vishnuvajhala
you cannot join two tables in a lookup. Lookup works only
on one underlying table.
