Hi, what's your version ? in 4.11 the two forms work : mysql> select concat(firstname,' ','lastname') from names; +----------------------------------+ | concat(firstname,' ','lastname') | +----------------------------------+ | Jean lastname | +----------------------------------+ 1 row in set (0.00 sec)
mysql> select firstname,lastname from names where concat(firstname,' ','lastname') like '%J%'; +-----------+----------+ | firstname | lastname | +-----------+----------+ | Jean | Dupond | +-----------+----------+ 1 row in set (0.00 sec) mysql> select firstname,lastname from names where concat(rtrim(ltrim(firstname)),' ',lastname) like '%Jean Dupond%'; +-----------+----------+ | firstname | lastname | +-----------+----------+ | Jean | Dupond | +-----------+----------+ 1 row in set (0.02 sec) mysql> select firstname,lastname from names where concat(firstname,' ',lastname) like 'Jean Dupond'; +-----------+----------+ | firstname | lastname | +-----------+----------+ | Jean | Dupond | +-----------+----------+ 1 row in set (0.00 sec) BUT i Think that : ********************* to use index on firstname or lastname, it's better to split $user rather than concat the two columns : mysql> select firstname,lastname from names where firstname like substring_index('%Jean Dupond%',' ',1); +-----------+----------+ | firstname | lastname | +-----------+----------+ | Jean | Dupond | +-----------+----------+ 1 row in set (0.00 sec) mysql> select firstname,lastname from names where lastname like substring_index('%Jean Dupond%',' ',-1); +-----------+----------+ | firstname | lastname | +-----------+----------+ | Jean | Dupond | +-----------+----------+ 1 row in set (0.00 sec) Mathias Selon Matt Babineau <[EMAIL PROTECTED]>: > Hey All- > > Got a fun question - I hit the manual but not much luck on my question.
