Okay ... so I have a query that works fine in RBO (8161). In CBO (9201) is returns wrong results (stats are recreated this AM). By adding a group by the CBO query returns the right data.

Furthermore on CBO, the explain plan shows that Oracle is not even parsing the query completely. If drops off a huge EXISTS clause.

Does anyone know what is going on? I have a sev 1 tar open and waiting for OWS to call me.
