RE: DELETE FROM table UNRECOVERABLE?

UNRECOVERABLE is the 7.x version of NOLOGGING. However, UNRECOVERABLE and NOLOGGING never worked for a DELETE statement.

If someone wrote something like:
delete from some_big_table unrecoverable;

all they did was succeed in assigned some_big_table a table alias, "unrecoverable". ;-)

Subject: DELETE FROM table UNRECOVERABLE?

I'm seeing this statement being issued in one database. I cannot find the
UNRECOVERABLE keyword in the 9i SQL Reference. Is UNRECOVERABLE perhaps
an old keyword that is now ignored by Oracle? I did some quick testing with AUTOTRACE, and noted no difference for the

values for Redo Size as compared to a DELETE w/o UNRECOVERABLE, nor did it=20
have any impact on the HWM.
