Hallo Experts,

I have done a mathematical equation based on columns and I want to only get the values < 10 and > 10. I have tried using Having but it isn't working. It still shows me the 0 values.

An Example;

Thnx

What I have tried:

SQL

SELECT DISTINCT 
 ProjectNr,
 SUM(GWVS) - SUM(GWVS2) AS GWValue1,
 SUM(ABVS) - SUM(GWVS2) AS GWValue2,
 SUM(TSVS) - SUM(GWVS2) AS GWValue2
FROM TBL1
WHERE RB IN (North)

GROUP BY ProjectNr

HAVING
SUM(GWVS) - SUM(GWVS2) <>10

What "values" do you want to be <10 or >10? GWValue1 etc? Do you want those values included in the SUM and just not shown? Or do you want them included from the SUM?

HiThe values < or > 10 to be returned should be the one in the HAVING clause

Hardly surprising that it's returning the 0 values, since 0 is less than 10! :)

If you want to exclude 0 values also, then you have to provide this constraint in your query:

SQL

SELECT DISTINCT 
 ProjectNr,
 SUM(GWVS) - SUM(GWVS2) AS GWValue1,
 SUM(ABVS) - SUM(GWVS2) AS GWValue2,
 SUM(TSVS) - SUM(GWVS2) AS GWValue2
FROM TBL1
WHERE RB IN (North)
 
GROUP BY ProjectNr
 
HAVING
 (SUM(GWVS) - SUM(GWVS2)) <> 10
 AND (SUM(GWVS) - SUM(GWVS2)) <> 0
