Divide By Zero Error Encountered In Sql Server 2008

Is there a simpler way of doing this? Here's my code: Percentage = CASE WHEN AttTotal <> 0 THEN (ClubTotal/AttTotal) * msg 8134 level 16 state 1 line 1 divide by zero error encountered 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.

NULLIF compares two expressions and returns null if they are equal or the first expression otherwise. Rewrite the query as: SELECT club_id, males, females, males/NULLIF(females, 0) AS ratio FROM school_clubs; Any number divided by divide by zero NULL gives NULL, and no error is generated.

2,047 Hi All,I have the following SQL where I calculate the percentages. The SQL is giving an error - can not divide by zero.CODESELECT class,(sum(count) / (SELECT sum(count) from table where mystatus = 888)) as CountPct,(sum(Amount) / (SELECT sum(Amount) from table where mystatus = 999)) as AmountPctFrom TableAGROUP BY ClassIt is obvious that the row is returning 0 (zero) and am trying to devide with it. Is there a way around with this problem. When I tried this it worked fine.CODE(sum(Amount) / (SELECT sum(Amount)+0.01 from table where mystatus = 999)) as AmountPctI even tried using NVL/ISNULL. No luck. Please help.Thanks a lot in advance. dave View Member Profile May 28 2005, 06:01 PM Post #2 Advanced Member Group: Members Posts: 5,208 Joined: 8-October 04 Member No.: 785 what do you want to happen if it is 0?there is an exception zero_divide you can catchm then deal with if you want psus View Member Profile May 28 2005, 08:38 PM Post #3 Newbie Group: Members Posts: 7 Joined: 9-May 05 Member No.: 2,047 just return a value, probably... a safedivide. michaelasc View Member Profile May 30 2005, 04:58 AM Post #4 Advanced Member Group: Members Posts: 189 Joined: 5-May 05 From: Cookeville, Tennessee Member No.: 2,014 HiOne way around this is use use a DECODE, such that:CODEDECODE(sum(divisor),0,0,sum(dividend)/sum(divisor)) will return zero if sum(divisor) is zero otherwise the calculation will be applied.Best wishesMichael « Next Oldest · Oracle Forum · Next Newest » 1 User(s) are reading this topic (1 Guests and 0 Anonymous Users) 0 Members: Forum Home Search Help Oracle |-- Oracle Forum Display Mode: Standard · Switch to: Linear+ · Switch to: Outline Track this topic · Email this topic · Print this topic · Subscribe to this forum Lo-Fi Version Time is now: 11th October 2016 - 02:30 AM Powered By Invision IPB © 2016 IPS, Inc.
