Tsql Divide By Zero Error Encountered
Msg 8134, Level 16, State 1, Line 1 Divide 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 oracle sql divide by zero 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 4,89331220 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 Fo
Prevent Divide-By-Zero Errors In SQL By Ben Nadel on October 3, 2007 Tags: SQL Boyan Kostadinov just sent me a cool link to an article that is the

I haven't read the first three parts yet, but there is a really cool tip in the fourth part on sql nullif using NULLIF() to prevent divide-by-zero errors in a 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 http://stackoverflow.com/questions/861778/how-to-avoid-the-divide-by-zero-error-in-sql SQL call. Therefore, running this code:
8 knows that division by zero is a no-no, or at least they should. Everybody who's used SQL for any amount of time knows that we http://www.itjungle.com/fhg/fhg051210-story02.html can use a CASE expression to prevent division by zero. But do you know the other way to prevent division by zero in SQL? Assume a database file called SomeTable, with fields called Quantity and Amount. Let's divide Amount by Quantity. First, here's the usual case statement. select itnbr, Amount, Quantity, case when Quantity <> 0 then Amount / Quantity else 0 end from SomeTable If divide by Quantity is not zero, the division takes place. If Quantity is zero, the calculation yields a zero. We could just as easily return any other numeric value, the value one, for example. select itnbr, Amount, Quantity, case when Quantity <> 0 then Amount / Quantity else 1 end from SomeTable The other way to prevent division by zero is to use the NULLIF function. NULLIF divide by zero requires two arguments. If the arguments are equal, NULLIF returns a null value. If they are not equal, NULLIF returns the first value. Here's the SQL. select itnbr, Amount, Quantity, Amount / nullif(Quantity,0) from SomeTable If Quantity is not zero, the two arguments do not match, and the resulting calculation is Amount divided by Quantity. But if Quantity is zero, the arguments do match, and the calculation is Amount divided by null, which yields a null value. If you use this technique, be sure to put the zero in the second argument of NULLIF.
