way to prevent a Divide By Zero error in SQL up vote 9 down vote favorite 2 I have a SQL query which used to cause a Divide By Zero exception, I've wrapped it in a CASE statement to stop this from happening. Is there a simpler way of doing this? Here's my code: Percentage = CASE WHEN AttTotal <> 0 THEN (ClubTotal/AttTotal) * divide by zero error encountered in stored procedure 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 25 down vote accepted A nicer way of doing this is to use NULLIF like this: Percen

SQL call.The idea here is that, as with any other form of math that I know of, you cannot divide by zero in a SQL call. Therefore, running this code:SELECT( 45 / 0 ) AS value;... results in a SQL error being thrown:Error Executing Database Query. [Macromedia] [SQLServer JDBC Driver] [SQLServer] Divide by zero error encountered.To prevent this sort of error from being thrown, author Hugo Kornelis suggests using a NULLIF() in the divisor of the equation. NULLIF() takes two arguments and returns NULL if the two values are the same and can be used to turn http://www.bennadel.com/blog/984-using-nullif-to-prevent-divide-by-zero-errors-in-sql.htm the divisor from a zero into a NULL which, in turn, will force the entire equation to become NULL. Therefore, running this code:SELECT( 45 / NULLIF( 0, 0 ) ) AS value;[ #qDivision.value# ]... we get the following output:[ ]Here, the NULLIF( 0, 0 ) returns NULL since zero is equal to zero, which gets the SQL statement to return NULL, which gets ColdFusion to show an empty string. This is a seemingly pointless example since both zero values are hard coded, but imagine if this were a user-entered value, or even better yet, a SQL aggregate or other calculated value (such as might be used in a report or data mining exercise).Now, let's say you want to take this one step further and provide a default value for the equation if NULL is encountered (A default value, though not entirely accurate might make your consuming code more compact as it won't have to deal with exception cases). To set a default value, we could use the ISNULL() or COALESCE() functions:SELECT(ISNULL((45 / NULLIF( 0, 0 )),0)) AS value;
