Compare 2 dates in mysql


I need to compare 2 dates in mysql but I only have version 3.23 of mysql installed and cannot upgrade.


With mysql 4.1.1 the function datediff(date1,date2) and others were introduced.

If you are using 4.0 or older, you need to use to_days(date1) and subtract in this form:

select TO_DAYS(NOW()) - TO_DAYS(last_modification)
 from mytable;
