if i am not mistaken SELECT SUM(colname) WHERE value = 'value' only return one row, and that's the sum you want i guess.

Hi all, I'm trying to add all the values from the same column in MySQL with a query like this: SELECT SUM(colname) WHERE value = 'value' But then I can't output it on the screen correctly. I've tried to put all the results into an array and then make an array_sum($arrayname) and it gives me exactly the double of what it should... any suggestions? By the way, the column I'm trying to add is a DOUBLE 6,2. Thanks in advance, Cesar L.
