Solution 2

Hi,

I am updating the solution 1.

SQL

Select Name, ColumnA, ColumnB, Test, TestAA, (ISNULL(ColumnA, 0) + ISNULL(ColumnB, 0)  + ISNULL(Test, 0) + ISNULL(TestAA, 0)) AS 'SUM' from yourtableName

if you do not use ISNULL function then, if anyone value goes NULL then whole sum will go null. so, using isnull function we will replace null value with 0.

hope it helps.
