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 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 4,89

Oracle Sql Divide By Zero
just sent me a cool link to an article that is the msg 8134 level 16 state 1 line 1 divide by zero error encountered final part in a four part series that discusses the SQL NULL value. I haven't read the first divide by zero error encountered excel three parts yet, but there is a really cool tip in the fourth part on using NULLIF() to prevent divide-by-zero errors in a SQL call.The idea here is that, as http://stackoverflow.com/questions/861778/how-to-avoid-the-divide-by-zero-error-in-sql with any other form of math that I know of, you cannot divide by zero in a SQL call. Therefore, running this code:

Causes: This by zero 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 by zero error 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
