Divide By Zero Error Encountered Sql Server 2008
by zero error encountered. What is the best way 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 divide by zero error encountered excel 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 4,89331220 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 10.2

Home>SQL Server Error Messages> Msg 8134 - Divide by zero error encountered SQL Server sql nullif Error Messages - Msg 8134 - Divide by zero error encountered SQL Server Error Messages - Msg 8134 Error Message Server: divide by zero error encountered. the statement has been terminated Msg 8134, Level 16, State 1, Line 1 Divide by zero error encountered. Causes: This error is caused by performing a division operation wherein the denominator or the divisor is 0. This error is not http://stackoverflow.com/questions/861778/how-to-avoid-the-divide-by-zero-error-in-sql 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 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 http://www.sql-server-helper.com/error-messages/msg-8134.aspx 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 value in a calculation involving a divide-by-zero error. To return a 0 value instead of a NULL value, you can put the division operation inside an ISNULL function: SET ARITHABORT OFF SET ANSI_WARNINGS OFF SELECT ISNULL([Numerator] / [Denominator], 0) Related Articles : Frequently Asked Questions - SQL Server Error Messages Frequently Asked Questions - INSERT Statement Frequently Asked Questions - SELECT Statement
SERVER - How to Fix Error 8134 Divide by Zero Error Encountered August 27, 2016Pinal DaveSQL Tips and Tricks5 commentsHere is one of the most popular questions: How to overcome (Error 8134) Divide by Zero Error Encountered in SQL Server?Before we see http://blog.sqlauthority.com/2016/08/27/sql-server-fix-error-8134-divide-zero-error-encountered/ the answer of this question, let us see how to recreate this error.Run following script in SQL Server Management Studio window.DECLARE @Var1 FLOAT; DECLARE @Var2 FLOAT; SET @Var1 = 1; SET @Var2 = http://www.peachpit.com/blogs/blog.aspx?uk=Avoiding-division-by-zero-with-NULLIF-Five-SQL-Tips-in-Five-Days-Part-5- 0; SELECT @Var1/@Var2 MyValue;When you execute above script you will see that it will throw error 8134. Msg 8134, Level 16, State 1, Line 6 Divide by zero error encountered. Here is the divide by screenshot of the error.Now there are multiple ways to avoid this error to happen. We will see two of the most popular methods to overcome this error.Method 1: Use NullIf FunctionHere is the SQL script with NullIf FunctionDECLARE @Var1 FLOAT; DECLARE @Var2 FLOAT; SET @Var1 = 1; SET @Var2 = 0; SELECT @Var1/NULLIF(@Var2,0) MyValue;When you use the NULLIF function, it converts the zero value to Null and divide by zero leading to the entire result set to be NULL instead of an error.Method 2: Use Case StatementHere is the SQL script with CASE StatementDECLARE @Var1 FLOAT; DECLARE @Var2 FLOAT; SET @Var1 = 1; SET @Var2 = 0; SELECT CASE WHEN @Var2 = 0 THEN NULL ELSE @Var1/@Var2 END MyValue;When you use CASE statement, it converts the zero value to Null and leading to the entire result set to be NULL instead of an error.Let me know if you have any other alternate solution.

By Chris FehilyJul 25, 2008 Topics: ProductivitySuppose you want to calculate the male–female ratios for various school clubs, but you discover that the following query fails and issues a divide-by-zero error when it tries to calculate ratio for the Lord of the Rings Club, which has no women: SELECT club_id, males, females, males/females AS ratio FROM school_clubs; You can use the function NULLIF to avoid division by zero. 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 NULL gives NULL, and no error is generated.
