MySQL query to count non-null values in a single row

Question

I\'m trying to put together a MYSQL query that will count the number of Non-Null (or better yet, non-zero) values in select fields in a single row and then sort from lowest to h

Answer 1

This should do what you want:

SELECT ID, Name, Score_1, Score_2, Score_3
FROM Table1
ORDER BY (Score_1 = 0) + (Score_2 = 0) + (Score_3 = 0)

Result:

ID  Name   Score_1  Score_2  Score_3
4   Mike   4        5        5      
1   Dan    8        7        0      
2   Joe    0        0        3      
3   Chris  0        0        0
