I cannot peoclaim it with absolute authority not being privy to Oracle internals;
however it would make sense to hash the table b_tab.

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?
| Operation | Name |
-----------------------------------------------------------------------
| 0 SELECT STATEMENT | |
| 1 0 HASH JOIN | |
| 2 1 TABLE ACCESS FULL |B_TAB |
| 3 1 INDEX FAST FULL SCAN |PK_A_TAB |
