Is there a way to subtract an amount of days from a date in SQL?

Question

I know about DATEDIFF(d, date1, date2), but I am not looking to subtract two dates, rather an amount of days from a date.

For example:

"2010-04-13" - 4 = "2010-04-09"

Is that possible with mySQL?

Answer 1

Yes. See http://dev.mysql.com/doc/refman/5.1/en/date-and-time-functions.html#function_adddate

SELECT DATE_ADD('2008-01-02', 31);

Results in:

'2008-02-02'

To subtract, just use a negative number, or use DATE_SUB

Answer 2

yes. Mysql has plenty of date functions. Just google mysql datetime functions and you'll get the list. Date subtraction ones among them

Answer 3

date_sub(date,interval 4 day);
