Nice challenge ;-)
For MySQL 4.0.x:
SET @d='01/02/03';
SELECT DATE_FORMAT(
CONCAT_WS(
'-',
SUBSTRING(@d, LOCATE( '/', @d, LOCATE( '/', @d)+1)+1) ,
SUBSTRING_INDEX(@d, '/',1),
SUBSTRING(SUBSTRING_INDEX(@d,'/',2), LOCATE('/', SUBSTRING_INDEX(@d,
'/', 2))+1)
),
'%Y-%m-%d %H:%i:%s');
(Works for both formats you specified; replace @d with column name)
For MySQL 4.1.1+:
SET @d='01/02/03';
SELECT STR_TO_DATE(@d, '%m/%d/%Y');
(not tested)
