MYSQL Order By Sum of Columns
I think you should be able to do
SELECT *, col1+col2 as mysum ORDER BY mysum
Which is essentially the same as you already have
Why not try before concluding it doesn't work? In point of fact, it does.
Suppose you have a table named 'Students'
Now you want to know the total marks scored by each student. So, type the following query
SELECT Name, S1, S2, SUM(S1+S2) AS TOTAL
FROM Students
GROUP BY Name, S1, S2
ORDER BY Total;
You will get the following result.
