See my comment on my answer for a brief explanation and then choose whether you want your original answer or mine. The actuall NULLIF function definition is simply a case statement under the hood, but it has this nice compact form :) nullif (@a, @b) means case when @a = @b then NULLIF compares two expressions and returns null if they are equal or the first expression otherwise. The ending inventory is 0. http://applecountry.net/divide-by/divide-by-zero-error-sql-2005.php

I would rather signal to the user that the result is unknown because the divisor is zero. –Henrik Staun Poulsen Sep 17 '15 at 11:49 add a comment| up vote 1 Divide By Zero Error Encountered In Sql Server select itnbr, Amount, Quantity, case when Quantity <> 0 then Amount / Quantity else 0 end from SomeTable If Quantity is not zero, the division takes place. To return a 0 value instead of a NULL value, you can put the division operation inside an ISNULL function: SET ARITHABORT OFF SET ANSI_WARNINGS OFF SELECT ISNULL([Numerator] / [Denominator], 0) For any SQL Server Performance Tuning Issue send email at pinal @ sqlauthority.com .

Thank you. But if you convert the result from NULL to Zero, then you simply get wrong and misleading results. –George Nov 26 '15 at 17:48 3 By the way, if you CASE statements are powerful and can be used just about anywhere:SUM( objid ) / (CASEWHEN COUNT( units_purch ) = 0THEN NULLELSE COUNT( units_purch )END)As you can see, NULLIF() is a lot useful reference my form submited well without any error.

But, just a guess. So if the denominator is 0, then the result of the division will be NULL.
I am shocked that this gets 71 upvotes! I very seldom downvote, but this is really crap! In SQL, dividing by NULL returns NULL. Making the initial query a subselect and then doing a GROUP BY on the outer query also changes the results because there is division involved. –Andrew Steitz Mar 1 '13 at
