Question

I have the following query:

SELECT BaDebet2 - BaCredit2 AS TOTAL FROM balansen

edit

I only want to sum up all BaDebet2 records when TOTAL is greater then 0

Answer 1

I think that will solve your problem. The second query will deliver BaDebet2 if BaDebet2 – BaCredit2>0, otherwise 0.

SELECT SUM(BaDebet2_Actual) FROM 
(SELECT IF(BaDebet2 - BaCredit2>0, BaDebet2 ,0) AS BaDebet2_Actual 
 FROM balansen) A;
