Greetings All.
I have a record on my database with a last name of 'DeFelice'.
I want to be able to retrieve that record whether a user enters 'DeFelice', 'Defelice', 'defelice', or 'DEFELICE'. Is there a way I can do that? Is that what the "ilike" function does?
I'm on 7.0.3.
Thanks in advance,
Tom Sattler

CREATE INDEX lname_lower ON person ( lower(lname) );
(above step is optional, but helps performance)
SELECT * FROM person WHERE lower(lname) = 'defelice'
should be faster than ILIKE.

~* Match (regex), case insensitive is what you are looking for.

For a situation like this I have always used the upper() function :
SELECT
*
FROM
table_name
WHERE
upper( last_name ) = 'DEFELICE';
This way, regardless of what is stored in the last_name field, it is forced
to upper before the comparison (it doesn't later what is actually in the
field, so it's safe that way).
I'm not positive, but I believe this is more efficient than RegEx. The nice
thing about RegEx is it is generic and has many purposes. The bad thing
about RegEx is that *BECAUSE* it is generic, it does none of those things
particularly efficiently.
Good Luck!!

Check out PGCluster, Slony-I, PITR (Warm Standby) and Skytools.
