Thanks for solving this all, I have do something ugly because I only have the yyyy-mm (3rd party DB) which ends up like this:
Mysql> select dayofmonth((concat('2004-02','-01') + interval 1 month) - interval 1 day); Urrggg ;) Still, much more graceful (and more future proof) than what I just came up with: select case when (right('2002-04',2) = '02') then 28 when ('%09%04%06%11%' regexp right('2002-04',2)) then 30 else 31 end as daysinmonth; lol.... Thanks Andrew Sql,query * Roger Baklund >You can start with the first day of the _next_ month, and go 1 day back...: > >mysql> select dayofmonth('2002-11-01' - interval 1 day); --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
