calculating with time & date
Hi, Can anyone help me to make a sql query (for a php website) in which to calculate with date and time??
There is: Userid, Begintime, Endingtime and Date. I have to get the hours a month (howmuch the person has worked that month). So userid x has worked y hours in january... rather nasty... Any help is welcome!

In general it should look like this (PSEUDO-SQL)
Code:
SELECT year(date), month(date), sum(endingtime-begintime) GROUP BY year(date), month(date) But it's specific to the DB and used datatypes.

Forgot the userid and the from clause, sorry.
Code:
SELECT userid, year(date), month(date), sum(endingtime-begintime) FROM mytable GROUP BY userid, year(date), month(date)
