Trying to create safe website where security is handled by the website and not the user How does an exponent work when it's less than one? select itnbr, Amount, Quantity, case when Quantity <> 0 then Amount / Quantity else 1 end from SomeTable The other way to prevent division by zero is to use the NULLIF Wim de Lange Jul 30, 2012 at 7:38 AM 1 Comments Nice! 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. http://darrenmanning.com/divide-by/divide-by-zero-error-encountered-sql-2008.html
todd sharp Oct 3, 2007 at 10:45 PM 48 Comments Excellent find! The biggest problem is that you cannot distinguish between a correctly computed 0 being returned or a 0 as the result of an error. Therefore, running this code:
Then by IFNULL it returns 0 as the result is NULL here. I received values 0,0,0,0,0, in all fields. At least Oracle's implementation of NULLIF doesn't accept NULL value as valid parameter and returns error message about it.So, in complete form it looks like:nullif(nvl(divisor,0),0)NVL will change NULL on 0 and
Therefore, running the above code, we get the following output:[ 0 ]As someone who runs a ton of reports on database table (albeit, not in any educated way), this is going Here is my test: -- test data create table dbo.IsnullAndNullifVersusCase ( col1 int not null identity(1, 1) primary key clustered, col2 int not null ); go this is painfully slow, but But encountering the nulls prompts the question. Divide By Zero Error Encountered Excel By automatically letting 0 be the default for nulls you are introducing potentially quite significant bias into your data sets.So, without labouring the point, I recommend that you reconsider this last

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 this please help.ISNULL(table/NULLIF((table),0),0)*100 Lain Inverse Oct 21, 2012 at 3:29 AM 2 Comments Addendum:In case when divisor could be NULL it's important to NVL it to ZERO.
We could just as easily return any other numeric value, the value one, for example. Msg 8134 Level 16 State 1 Line 1 Divide By Zero Error Encountered But, I wanted to be able to easily take it down to refill/reprogram/change the batteries, so I used Velcro instead of the tape. This happens when a number is divided by 0 (zero). The mounting bracket did not fit on the edge of my tank and it comes with double sided tape just in case that happens.
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 https://ask.sqlservercentral.com/questions/22402/best-way-to-avoid-divide-by-zero.html ANSWER: I think there's an underlying issue here, which is that division by 0 is not legal.
