Answer / kalyan
we have the lOOKUP OVERRIDE Query in the Lookup
transformation. Use the SQl Query to join the tables you
lookup on. Thsi is similar to what yo do at the Source

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 / bsgsr
join the tables in the database itself then do the look up
else override the lookup sql and look up.
i believe this would work.

Lookup transformation: Based upon one/more keys the data is
retreived from one/more tables.
create a single lookup transformation by Joining the
multiple tables, having connected the keys defined in
lookup tranformation.

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