Greetings...
I'm being asked to use ORACLE HASHES to perform JOINs...

I have two tables.  each with 5 fields each...
unfortunately I have to join against all 5 fields, and it's slowing down the lookup.

I was told to implement a ORACLE HASH in the second table, and perform the join against the HASH from the first table.

How do I do this?  Am I even asking this question correctly?
