Hi,
I am running this code :-

select temp16.*,(Pasea_Cost_Price/NULLIF(UNIT_CASE,0)) as Pasea_CP_Modified

from temp16

Now , I am seeing NULL values in Pasea_CP_Modified,
I want to see a 0 in place of a NULL value.
How to do tht??

WHEN UNIT_CASE IS NULL THEN 0
WHEN UNIT_CASE = 0 THEN 0
ELSE Pasea_Cost_Price/UNIT_CASE*1.00
END AS Pasea_CP_Modified
from temp16

he's saying that if UNIT_CASE is and integer type (smallint / bigint / int) then you'll get integer division which may not be what you want.

If UNIT_CASE is a DECIMAL/NUMERIC (same thing) or a FLOAT TYPE (or even a money type) then you'll get 'standard' division.

Just to clarify, if both the numerator and denominator are of an integer type, sql will provide the result as an integer type (thus no decimal places). If, either the numerator or denominator are of a decimal type, then the result will be based on the sql rules for converstion and such, but you (should) get a decimal result.

In this case, assuming that Pasea_Cost_Price is not an integer type, you should not need to multiply by 1.00. I'd also go so far to suggest not properly casting your data is bad form anyway, but that's a whole other topic.
