Question

I am writing a script for a car show. Users choose the car number and vote 1-5 on various criteria. There are multiple users voting for the same car, but they can only vote once for each car, I check for this.

Now I have a table of a unique carNumber and 1-5 votes for each criteria, per car.

Here is how I find the total score for each individual users vote

SELECT carNum, exterior+interior+engine AS Score FROM Judge_Votes WHERE catagory = '$catNum' ORDER BY carNum

Reults 
CarNum: Score:
18  11
14  8
13  15
12  8
12  11
2   14

I want to add up the total score from each user into a final score result. IE car 12 has 19 total score.

The question I have. How can I find the total score using sql or php?

Answer 1

Just use SUM and ORDER BY:

SELECT carNum, SUM(exterior+interior+engine) AS Score 
    FROM Judge_Votes 
    WHERE catagory = '$catNum' 
    GROUP BY carNum

That should do the “trick”
