FWIW -- Oracle Press recently published a "Backup & Recovery 101" book by Kenny Smith and Stephan Haisley. I have not yet read it, but it claims to have RMAN coverage. Since it is part of the '101' series, I presume it covers most of the basic stuff. Has anyone purchased it? And read it? I may check it out at IOUG-A next week :)

I'm wondering what you would like to see in such a book and would you use such a book? Ideas and comments welcome. Robert G.

I mean, you could change it to trunc the oracle_date field (that eliminates the minutes) and then do a to_date of :b1 but you will still be operating on the oracle_date field. Okay, I HATE to suggest this, but since the table is small: add another field to the table oracle_date_2 as a date field. Update the table set oracle_date_2=trunc(oracle_date) add a trigger to fill in oracle_date_2 when you insert a row or update the oracle_date column create an index on oracle_date_2 and change the query to use that column --- [EMAIL PROTECTED] wrote: > > I've got the following SQL statement that is running very long on a > nightly > data load.
