How to get this in decimal value instead of null

Question

i am trying to get value in Decimal in this query but unable to get i am getting NULL Value

SELECT CAST(CAST(CAST(SUM(CAST(0 AS INT)) AS DECIMAL(10, 2)) * 100 
         


        

Answer 1

Way too many CASTs in that SQL

Use a CASE if you don't want to use ISNULL, which is needed because you have NULLIF

SELECT 
  CAST(
    CASE
      WHEN SUM(CAST(0 AS INT)) + SUM(CAST(0 AS INT)) + SUM(CAST(0 AS INT)) = 0 THEN 0
      ELSE SUM(CAST(0 AS INT)) * 100.00 / (SUM(CAST(0 AS INT)) + SUM(CAST(0 AS INT)) + SUM(CAST(0 AS INT)))
  END
  AS DECIMAL(10, 2))

Howver, anything divided by zero is undefined or infinity: not zero.
