Hi,   When I use sql statement to select the date range from $_POST value,It doesn't work.   ------------------------------------------- "select * from mydatabase where mydate between '$_POST[start_date]' and '$_POST[end_date]' "   There is no error,but the result is not I want.   ps: (1)mydate attribute is timestamp (2)$_POST[start_date] is something like '2003/05/12'
