Re: Mass updates to production tables (NULL to non-NULL)

Try using dbms_xplan with SQL_TRACE switched on - the query it runs against the plan_table is very interesting. It includes code to pick up the plan of the recursive SQL that Oracle uses to populate temporary tables during (e.g. star transformations, subquery factoring).
