| | -- Accessing by ROW_ID in SQL/SPL is not a especially fast (cannot compare at all to the primary index). | |
If you use EXPLAIN you'll see the reason why: It's always using a Full Table Scan - they probably don't want the users to work with ROWID
too much ;-)

It is officially supported since R4
