Question

I am trying to get the sum hours for each month from a given user and having problems with the code. Need help.

what I have so far:

$sql = “SELECT sum(hours) AS total_Hours FROM flights WHERE month = 3
and username=’$myname'”;

This isn’t even working, But what i really need is total hours from user for each month.
possible?

Answer 1

Here is the query asking sum for each month:

SELECT SUM(`hours`) AS total_Hours, `month` FROM flights 
WHERE `username`='some_user'
GROUP BY `month`

Also you should know that your $myname variable must to be escaped with mysql_real_escape_string before passing in a query.

@Robbie is telling right about escaping month. It seems to be the only problem of your query.
