But somehow query optimizer do divide by zero while filtering. Even if you think you will never encounter this with your result set, it's advisable to guard against it because when divide by zero is encountered, an error is thrown.

So SQL can certainly shortcut to optimise, but not in any order that you can rely on. https://social.msdn.microsoft.com/Forums/sqlserver/en-US/83ea36f4-2fcc-46cc-b2a5-f4725b7eda94/divide-by-zero-error-encountered?forum=transactsql Management is interested in the percentage of zeros out of the total number of cases.

What's important is that when failures can happen, you always have the chance to use a CASE expression. sigh –Beska May 14 '09 at 19:12 9 I'm sorry, I didn't mean to offend you. Also, some checks for datatype convertibility of didn't work also...The call was made to MS and MS confirmed that with a new optimiser it's possible that validation of result may happen useful reference Seems odd as if you write: select 1 where 1=2or (1=2 and 1/0 > 1) which is semantically similar to your query, you get no rows returned Edited by
The Coalesce replaces the resulting NULL by 0. –GuiSim Apr 16 '14 at 15:59 3 PLEASE! Sql Nullif This is completely wrong in a mathematical sense, and it is even dangerous as your application will likely return wrong and misleading results. I find this to be much more straight forward and readable.
Please ignore.Also, you cannot depend on the order in which SQL will evaluate certain things. I was looking for a solution solving divide by zero problem without using case (the query was already too complex) and this is THE solution! The operation has to to throw, since the mathematical meaning of x/0 is different from the NULL meaning, so it cannot return NULL.
