How To Fix Divide By Zero Error In Sql Server
46 I have this error message: Msg 8134, Level 16, State 1, Line 1 Divide by zero error encountered. What is the best way to write SQL code so that I will never see this error message again? I could do either of the following: Add a where clause so that my divisor is never zero Or I could add a case statement, so that there is a special treatment for tsql divide by zero error encountered zero. Is the best way to use a NullIf clause? Is there better way, or how can this be enforced? sql sql-server sql-server-2005 sql-server-2008 share|improve this question edited Jan 6 at 19:50 Hooper 4241525 asked May 14 '09 at 6:06 Henrik Staun Poulsen 4,89331220 4 Perhaps some data validation is in order. –Anthony May 14 '09 at 19:17 add a comment| 15 Answers 15 active oldest votes up vote 350 down vote accepted In order to avoid a "Division by zero" error we have programmed it like this: Select Case when divisor=0 then null Else dividend / divisor End ,,, But here is a much nicer way of doing it: Select dividend / nullif(divisor, 0) ... Now the only problem is to remember the NullIf bit, if I use the "/" key. share|improve this answer edited Dec 20 '12 at 1:04 Community♦ 11 answered May 14 '09 at 6:10 Henrik Staun Poulsen 4,89331220 that's the way I would have solved it. –J. Polfer May 14 '09 at 19:21 4 A much nicer Way of doing it "Select dividend / nullif(divisor, 0) ..." breaks if divisor is NULL. –Anderson Dec 1 '14 at 10:51 add a comment| Did you find this question interesting?

Causes: http://stackoverflow.com/questions/861778/how-to-avoid-the-divide-by-zero-error-in-sql This error is caused by performing a division operation wherein the denominator or the divisor is 0. This error is not encountered when the denominator or divisor is NULL because this will result to a NULL value. Solution / Work Around: There are three ways to avoid the "Division by zero encountered" error in your SELECT statement and these http://www.sql-server-helper.com/error-messages/msg-8134.aspx are as follows: CASE statement NULLIF/ISNULL functions SET ARITHABORT OFF and SET ANSI_WARNINGS OFF Using the CASE statement, your query will look like the following: SELECT CASE WHEN [Denominator] = 0 THEN 0 ELSE [Numerator] / [Denominator] END AS [Percentage] FROM [Table1] If the denominator or divisor is 0, the result becomes 0. Otherwise, the division operation is performed. 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 NULL if it is zero. Then in the division, any number divided by NULL results into NULL. So if the denominator is 0, then the result of the division will be NULL. Then to return a value of 0 instead of a NULL value, the ISNULL function is used. Lastly, using the SET ARITHABORT and SET ANSI_WARNINGS, your query will look like the following: SET ARITHABORT OFF SET ANSI_WARNINGS OFF SELECT [Numerator] / [Denominator] With both ARITHABORT and ANSI_WARNINGS set to OFF, SQL Server w
OK, some of the data I am using isnt playing nicely and once in a while I get Divide by zero error encountered. Divide by zero error encountered. Msg 8134, Level 16, State 1, Line 2 To avoid this I am using a CASE as: DECLARE @Int1 AS https://ask.sqlservercentral.com/questions/22402/best-way-to-avoid-divide-by-zero.html INT , @Int2 AS INT SET @Int1 = 6 SET @Int2 = 2 SELECT @Int1 / http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=86596 @Int2 SET @Int1 = 6 SET @Int2 = 0 SELECT @Int1 / CASE WHEN @Int2 = 0 THEN 1 ELSE @Int2 END is there a better way of getting the same results but without littering by nice tidy SELECT statements with hundreds of CASE WHEN ... THEN ... ELSE ... END's?? Am I missing some super useful function that does this in one line? [edit]OK, divide by thanks for the answers so far. I dont want to lose rows where it is zero so, I cant accept a NULL in its place or to filter out those rows with a WHERE @int20 I simply want to replace a 0 value with a 1 value... more ▼ 0 total comments 973 characters / 178 words asked Oct 14, 2010 at 08:54 AM in Default Fatherjack ♦♦ 43.7k ● 79 ● 98 ● 117 edited Oct 14, 2010 at 11:03 AM divide by zero add new comment (comments are locked) 10|1200 characters needed characters left ▼ Everyone Moderators Original poster and moderators Other...

Good to know about NULLIF Oct 14, 2010 at 09:07 AM ozamora Håkan Winther Nope, the case statement is not any faster because NULLIF is the case statememt. 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 null else @a end Oct 14, 2010 at 09:50 AM Oleg @Håkan Winther Please accept my apologies, It looks like I cannot see straight today, so I did not notice isnull. I do believe though that in this situation the case is going to be only very-very-slightly faster. Oct 14, 2010 at 11:07 AM Oleg @Håkan Winther I did not know how to te
