Except it's really there and it's just that I was passing in a bad value...but I have no idea. Oct 14, 2010 at 09:30 AM Håkan Winther Good question Fatherjack - I've got CASE statments all through my code because of this. Steve May 5, 2010 at 2:02 PM 1 Comments I just updated my script with this code and it worked like a clock. Even if you think you will never encounter this with your result set, it's advisable to guard against it because when divide by zero is encountered, an error is thrown. get redirected here
In my case I have to use divide operation at WHERE clause. You may not be dealing with a nuclear reactor but hiding errors in general is bad programming practice. So it would be: Percentage = ISNULL(100 * ClubTotal / NULLIF(AttTotal, 0), 0) The inner part is evaluated to NULL and then ISNULL replaces it with 0. What are the drawbacks of the US making tactical first use of nuclear weapons against terrorist sites?
Excellent solution! Therefore, running this code:
Originally the question seemed to be phrased as "what can I do to just hide this error." Since then, it has evolved. This is completely wrong in a mathematical sense, and it is even dangerous as your application will likely return wrong and misleading results. SET ARITHABORT OFF SET and ANSI_WARNINGS OFF do it work - after 2 days of fighting with divide by zero at WHERE clause.

I was looking for a solution solving divide by zero problem without using case (the query was already too complex) and this is THE solution! https://ask.sqlservercentral.com/questions/22402/best-way-to-avoid-divide-by-zero.html NULLIF compares two expressions and returns null if they are equal or the first expression otherwise.

Using the NULLIF and ISNULL functions, your query will look like the following: SELECT ISNULL([Numerator] / NULLIF([Denominator], 0), 0) AS [Percentage] FROM [Table1] What this does is change the denominator into The annual rate of sales is $4,000 ($1,000/3)*12.
