Nullif Sql
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 sql-server-2005 sql-server-2008 share|improve this question edited Jan 6 at divide by zero error encountered in stored procedure 19:50 J.D. 4311525 asked May 14 '09 at 6:06 Henrik Staun Poulsen 4,92331220 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 352 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 4,92331220 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 10.2k1369107 answered Jan 4 '12 at 12:06 Tobias Domhan 1,4431011 8 Some benchmarks reveal that COALESCE is s

Causes: This 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 http://www.sql-server-helper.com/error-messages/msg-8134.aspx 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 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:
To Prevent Divide-By-Zero Errors In SQL By Ben Nadel on October 3, 2007 Tags: SQL Boyan Kostadinov just sent me a cool https://www.bennadel.com/blog/984-using-nullif-to-prevent-divide-by-zero-errors-in-sql.htm link to an article that is the final part in a four part series that discusses the SQL NULL value. I haven't read the first 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 with any other form of divide by math that I know of, you cannot divide by zero in a SQL call. Therefore, running this code:
