Try this:[CODE]Select COALESCE(CAST(tot_rev as NUMERIC(10, 2))/NULLIF(Act_count, 0), 0) as Avg_CHG from tbl_revenues;[/CODE]Make sure your front end tool has appropriate formatting set on the associated display field. |

I am planning to use within an etl tool the query straight forward, is there a way to have a query logic without coalesce. |

If you don't use COALESCE() you get NULL when the denominator is zero.quote: Originally posted by cplusplus I am planning to use within an etl tool the query straight forward, is there a way to have a query logic without coalesce.

[CODE]Select CASE WHEN (CAST(tot_rev as NUMERIC(10, 2))/NULLIF(Act_count, 0)) IS NULL THEN 0 ELSE (CAST(tot_rev as NUMERIC(10, 2))/NULLIF(Act_count, 0)) END as Avg_CHG from tbl_revenues;[/CODE] |
