Is there a simpler way 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 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 probabl

Divide by zero error encountered SQL Server Error Messages - Msg 8134 Error Message Server: Msg 8134, Level 16, State 1, Line 1 Divide by zero error encountered. Causes: This http://stackoverflow.com/questions/19631017/simple-way-to-prevent-a-divide-by-zero-error-in-sql 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 are as http://www.sql-server-helper.com/error-messages/msg-8134.aspx 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 will return a NULL va
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 INT , @Int2 AS INT SET https://ask.sqlservercentral.com/questions/22402/best-way-to-avoid-divide-by-zero.html @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 ... 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 divide by 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 add new comment (comments are locked) 10|1200 characters needed characters left ▼ Everyone Moderators Original poster and moderators Other... Viewable divide by zero by all users 4 answers: sort voted first ▼ oldest newest voted first 0 You can use NULLIF if you want to return null when division by zero: SELECT @int1 / NULLIF(@int2,0) -- returns NULL or SELECT @int1 / ISNULL(NULLIF(@int2,0),1) -- returns @int1 The CASE statement is probably much faster then the second option, but you can test the performance more ▼ 11 total comments 288 characters / 46 words answered Oct 14, 2010 at 09:04 AM Håkan Winther 16.5k ● 36 ● 45 ● 57 edited Oct 14, 2010 at 09:07 AM Always though about CASE on this one. 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 test performance of the functions for that very reason (if the number of records is huge then IO and memory come into play and if the number of records is small then test is useless) until I saw how Jeff Moden doe
