Does anyone know how the operation below is performed?  Which object has
the hashtable built on it and which object performs the lookup against the
hashtable once it's built?

-----------------------------------------------------------------------
|   0    SELECT STATEMENT                        |                    |
|   1  0 HASH JOIN                               |                    |
