Please note that "" (empty string) and NULL is not the same value.
The following query will return records where x is not null: SELECT * FROM db WHERE x IS NOT NULL; But since "" and NULL is different values, it might just as well return empty strings. If you want records where x actually contains something, i.e. neither NULL og an empty string, the following should work fine: SELECT * FROM db WHERE x <> ""; Regards, -Bjarte- > -----Original Message----- > From: bill [mailto:[EMAIL PROTECTED]] > Sent: Thursday, January 03, 2002 5:19 PM > To: [EMAIL PROTECTED] > Subject: [PHP-DB] finding records wiht non-null columns > > > Is there a better query than > > SELECT * > FROM some_database > WHERE some_column <> "" > > I had tried > > WHERE some_column <> NULL but that didn't work. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
