maybe i dont get the question, but for all records for the last 24 hours (1 day) i use: this is an insteresting page: http://www.mysql.com/doc/en/Date_and_time_functions.html i says: Here is an example that uses date functions. The following query selects all records with a date_col value from within the last 30 days: mysql> SELECT something FROM tbl_name WHERE TO_DAYS(NOW()) - TO_DAYS(date_col) <= 30; so for 24 hours... change the 30 in 1 :) is this what you mean? bye, mark snijders -----Original Message----- From: David Robley [mailto:robleyd@paradise.net.nz] Sent: vrijdag 11 oktober 2002 12:23 To: php-db@lists.php.net Subject: Re: easier way to do this?

I can't be hanged going through the docs right now, or I'd have a try at the syntax for you :-) -- David Robley Temporary Kiwi!
