I'm not sure I like it, but it might be useful to know of, some day. Msg 8134 Level 16 State 1 Line 1 Divide By Zero Error Encountered Here's the SQL. 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,
That doesn't answer the question though as it only results in a more meaningful error (closer to the source of the problem) rather than avoiding an error completely. –David Spillett Jan adam Apr 30, 2013 at 4:37 PM 1 Comments bennadel.com saves me again!

It worked, but it was just wordy and distracting. Instead any value returned is the computed value and if anything goes wrong an exception is thrown. Why didn't Monero developers just improve bitcoin? But if Quantity is zero, the arguments do match, and the calculation is Amount divided by null, which yields a null value.
Typically, no one thinks to specify that nulls should be excluded. but when I went to the C-Panel for to check and Grab out this form data. I find this to be much more straight forward and readable. The operation has to to throw, since the mathematical meaning of x/0 is different from the NULL meaning, so it cannot return NULL.
Create Function fnRatio(@Numerator decimal(10,2),@Demoninator decimal(10,2)) Returns decimal(10,2) Begin Return Case When @Demoninator = 0 then 0.00 When @Demoninator Is Null then Null Else @Numerator/@Demoninator End End Regards Jason share|improve this answer 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) isfahan Apr 14, 2012 at 2:22 PM 1 Comments hi.. If you end up doing something like this most likely your data model is wrong.
Let's divide Amount by Quantity. The reason is that SQL Server evaluates the source expression twice when it expands NULLIF into the equivalent CASE expression.

Suppose 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 In some cases when using statistics functions, 0 or even 1 is an acceptable result when divisor is zero. –Athafoud Feb 3 at 8:26 3 Doing hacks like this has Wim de Lange Jul 30, 2012 at 7:38 AM 1 Comments Nice!

Marc Funaro May 7, 2010 at 1:14 PM 20 Comments VERY late to the party here, but I had occasion to work on a Divide By Zero error today, and came I find that in most cases, having a zero is graphically equivalent to NULL and a whole lot easier to deal with. If the user puts zero in the amount, and you want 0 returned when they do that, then you should put in code at the business rules level to catch that
