This error is not encountered when the denominator or divisor is NULL because this will result to a NULL value. END's?? This is a business rule of how to calculate inventory turns. AKE Sep 25, 2012 at 2:38 PM 1 Comments Nice article and useful tip.However, slightly concerned about your concluding remark: ...in most cases, having a zero is graphically equivalent to NULL his comment is here
Not the answer you're looking for? Not the answer you're looking for? But this,time, let's provide a default value if the division isnot valid.--->
But do you know the other way to prevent division by zero in SQL? Rather than calculating something you state the value to return for the case that AttTotal is zero. Therefore, running this code:

Typically what I've seen is a sproc being used for client applications, rather than plain SQL. –Zymus Jan 7 at 7:11 add a comment| 3 Answers 3 active oldest votes up Transact Sql Divide By Zero 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
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! Divide By Zero Error Encountered.

But somehow query optimizer do divide by zero while filtering. http://darrenmanning.com/divide-by/divide-by-zero-error-in-ms-sql.html In SQL, dividing by NULL returns NULL. Adam Dec 27, 2011 at 3:18 PM 1 Comments I'm attempting to use this feature when calculating the average for a value, but I'm not certain if my syntax is correct This function takes two parameters and if they are equal, a NULL value is returned. T Sql Avoid Divide By Zero
SQL Server returns a NULL in a calculation involving an overflow or divide-by-zero error, regardless of this setting. Microsoft SQL Server Language Reference Transact-SQL Reference (Database Engine) SET Statements (Transact-SQL) SET Statements (Transact-SQL) SET ARITHIGNORE (Transact-SQL) SET ARITHIGNORE (Transact-SQL) SET ARITHIGNORE (Transact-SQL) SET ANSI_DEFAULTS (Transact-SQL) SET ANSI_NULL_DFLT_OFF (Transact-SQL) SET Msg 8134, Level 16, State 1, Line 2 To avoid this I am using a CASE as: DECLARE @Int1 AS INT , @Int2 AS INT SET @Int1 = 6 SET @Int2 weblink Aakansha May 2, 2010 at 1:36 AM 1 Comments Hi,Excellent find!Using this I soved my problem.
NULL might be more appropriate. Mssql Divide By Zero Error Encountered I knew about NULLIF() but did not realize dividing by NULL returns NULL (I thought it would be an error). What does 'apt-get install update' do?
Tweet This Provocative thoughts by @BenNadel - Using NULLIF() To Prevent Divide-By-Zero Errors In SQL Thanks my man — you rock the party that rocks the body! My average inventory is now 0. At least please remove the coalesce, then the division returns NULL instead of Zero, that's better. –George Nov 26 '15 at 17:38 4 @SQLGeorge While I agree with your argument, Divide By Zero Error Java 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)
I am facing a problem. todd sharp Oct 3, 2007 at 10:45 PM 48 Comments Excellent find! Typically, no one thinks to specify that nulls should be excluded. check over here So the most elegant way to overcome this is to use NULLIF function and compare @iter to zero.

This means that all my inventory is being converted and purchased by customers. Which means you need to travel up the line and figure out why you're getting 0 or be acceptable with returning null. 0 is never correct in this instance. –James Wilson See my comment on my answer for a brief explanation and then choose whether you want your original answer or mine.
The usual 'gotcha' is than most developers expect SQL to behave like procedural languages and offer logical operator short-circuit, but it does NOT. This is one of the reasons most modern programming languages implement structured exception handling to decouple the actual return value with an error / status code. What am I? I do believe though that in this situation the case is going to be only very-very-slightly faster.
Copy SET ARITHABORT OFF; SET ANSI_WARNINGS OFF GO PRINT 'Setting ARITHIGNORE ON'; GO -- SET ARITHIGNORE ON and testing. This type of answer should never be accepted in any form. Thanks a lot !!
