I haven't read division by zero error in access 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 division by zero error in teradata other form of math that I know of, you cannot divide by zero in a SQL call. Therefore, running this code:

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 the divisor from a zero into a NULL which, in turn, will force the entire equation to become NULL. Therefore, running this code:

Can I revisit this theme with, what is the best way to handle divide by error https://www.bennadel.com/blog/984-using-nullif-to-prevent-divide-by-zero-errors-in-sql.htm in SQL without repeating code... What I have in mind is quite frequently divided by error appears as the result of a lengthy formula calculation - and trying to burying a lengthy a lengthy formula calculation in a case statement gives you an exceedingly long result, which is not great for code maintenance. Wrapping the handling in a function is also not great for reasons of performance. So is there any simple way to do https://community.oracle.com/thread/1558158 the equivalent of (pseudo code) select IFerr( actual / (RidiculouslyLongConvulutedFormulaHereWhichSometimesYieldsZeroValues), 0) from dual Where IFerr works like NVL - except it yields 0 when the result is a number error, or the result otherwise? thanks, Robert. 13507Views Tags: none (add) This content has been marked as final.

You can apply it to every denominator in your formula, so that it yields NULL in case it evaluates to 0. For example, with t as ( select 1 numerator, 0 denominator from dual ) select numerator/nullif(denominator,0) as div from t; Like Show 0 Likes(0) Actions 2.

If you have a very old version of Oracle, then instead of NULLIF (:a, 0)you might have to do something like CASE WHEN :a != 0 THEN :a ENDEdited by: Frank Kulash on Oct 8, 2010 11:17 AM Like Show 0 Likes(0) Actions 3. Re: Divide by ZERO error. Hoek Oct 8, 2010 3:13 PM (in response to 798631) Make sure that :a is always greater than 0, else don't execute the formula. if :a > 0 then return ((:a - :b)/:a) *100; else return 0; -- or whatever you want end if; Like Show 0 Likes(0) Actions 4.

Re: Divide by ZERO error. hm Oct 8, 2010 3:16 PM (in response to 798631) You should not divide by 0. You could change your code e.g.: if :a != 0 then return ((:a - :b)/:a) *100; end if
