What is the best way how to fix divide by zero error in sql server 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 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

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| up vote 87 down vote In case you want to return zero, in case a zero devision would happen, you can use: SELECT COALESCE(dividend / NULLIF(divisor,0), 0) FROM sometable For every divisor that is zero, you will get a zero in the result set. share|improve this answer edited Jan 15 '13 at 19:41 Peter Mortensen 10.2k1369107 answered Jan 4 '12 at 12:06 Tobias Domhan 1,4431011 8 Some benchmarks reveal that COALESCE is slightly slower than ISNULL. However, COALESCE is in the standards

Is there a simpler way http://stackoverflow.com/questions/861778/how-to-avoid-the-divide-by-zero-error-in-sql of doing this? Here's my code: Percentage = CASE WHEN AttTotal <> 0 THEN (ClubTotal/AttTotal) * 100 ELSE 0 END sql sql-server-2008 tsql sql-server-2005 share|improve this question asked Oct 28 '13 at 9:22 Denys Wessels 10.5k43872 1 It depends on how you wan't your query and result to behave when AttTotal is 0 or NULL, so there is no general way of doing it. I'd say your query is just fine. Even if you write your query differently using ISNULL or NULLIF at the end it will http://stackoverflow.com/questions/19631017/simple-way-to-prevent-a-divide-by-zero-error-in-sql likely execute the same. –Nenad Zivkovic Oct 28 '13 at 9:34 As has been pointed out by others, the logic in this CASE statement doesn't quite make sense to us. See my comment on my answer for a brief explanation and then choose whether you want your original answer or mine. My answer would be a more usual solution. –Tom Chantler Oct 28 '13 at 9:40 1 Possible duplicate of How to avoid the "divide by zero" error in SQL? –Henrik Staun Poulsen Mar 10 at 21:06 add a comment| 5 Answers 5 active oldest votes up vote 26 down vote accepted A nicer way of doing this is to use NULLIF like this: Percentage = 100 * ClubTotal / NULLIF(AttTotal, 0) share|improve this answer answered Oct 28 '13 at 9:25 Tom Chantler 11.2k42940 2 This will return NULL if AttTotal = 0, while the query in question returns 0. –Nenad Zivkovic Oct 28 '13 at 9:31 3 @NenadZivkovic - Returning NULL for a divide by zero error probably makes more mathematical sense anyway though. –Martin Smith Oct 28 '13 at 9:34 I agree with @Martin Smith. If you have a situation where the ClubTotal is a number and AttTotal is zero, it doesn't make sense to return zero. Or any other number :-) Returning zero implies ClubTotal is zero and AttTotal is more than zero. –Tom Chantler Oct 28 '13 at 9:38 add a comment| up vote 6 down vote I'm using NULLIF bit differently, because in some cases I do have to return
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 https://ask.sqlservercentral.com/questions/22402/best-way-to-avoid-divide-by-zero.html I am using a CASE as: DECLARE @Int1 AS INT , @Int2 AS INT SET @Int1 = 6 SET @Int2 = 2 SELECT @Int1 / @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 ... by zero ELSE ... END's?? Am I missing some super useful function that does this in one line? [edit]OK, 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 by zero error asked Oct 14, 2010 at 08:54 AM in Default Fatherjack ♦♦ 43.7k ● 79 ● 98 ● 117 edited Oct 14, 2010 at 11:03 AM 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 Pleas
