Well, it never occurred to me that they would do something like that (an
alias),
what would be the point?
Since they are deleting every record from the table, I thought it was
simply
some old-timer method for emulating a truncate back from the days of
Oracle 5 or 6,
maybe some decrepit ex-COBOL programmer hired to write Informatica code.

I hope you know it's an alias for the table.

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.
