I have the book, and it is a pretty good 101 book. My book seeks to go to
the next level, looking at things like the data dictionary views, the
recovery catalog tables and how they are used, backup and recovery case
studies, and the like. I will look for input from this thread for additional
content.

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 contemplating doing an Rman backup and recovery handbook. I'm wondering
what you would like to see in such a book and would you use such a book?
Ideas and comments welcome.

I don't think you can do it.. 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
