Your select works fine within the month to the exception of the first day because curdate()-1 is treated as a numeric field (see curdate in http://www.mysql.com/doc/en/Date_and_time_functions.html)
The following seems to be what you want to do: mysql> select date_format(curdate()- interval 1 day,'%Y%m%d'); +-------------------------------------------------+ | date_format(curdate()- interval 1 day,'%Y%m%d') | +-------------------------------------------------+ | 20040229 | +-------------------------------------------------+ 1 row in set (0.00 sec)
or, if you want the '-' mysql> select date_format(curdate()- interval 1 day,'%Y-%m-%d'); +---------------------------------------------------+ | date_format(curdate()- interval 1 day,'%Y-%m-%d') | +---------------------------------------------------+ | 2004-02-29 | +---------------------------------------------------+ 1 row in set (0.00 sec)
You don't really need date_format for the latter, as you've specified the default format. You could just use:
mysql> select curdate() - interval 1 day; +----------------------------+ | curdate() - interval 1 day | +----------------------------+ | 2004-02-29 | +----------------------------+ 1 row in set (0.00 sec)
