If you would like see SQL perform this math you can write "select 10000/(17.00/17.00/17.00) AS Result2" then we will get result in decimal or float however even this won't be completely Thanks a million! Everybody who's used SQL for any amount of time knows that we can use a CASE expression to prevent division by zero. Division of two inegers leads to INTEGERBODMAS stands for Brackets, Orders (ie Powers and Square Roots, etc), Division, Multiplication, Addition and Subtraction.The order is as follows:Step1: 10000/(17/17/17) (paranthesis first) Step2: 10000/(17/17/17) his comment is here

I'm sure there is no zero divider, because when I comment WHERE out, there is no zero values at results. Here's the SQL. I like your test setup. SET ARITHABORT OFF SET and ANSI_WARNINGS OFF do it work - after 2 days of fighting with divide by zero at WHERE clause.
It is because of integer type has a scale of 0.Now, the expression becomes 1000 / 0 which results in division by zero error.Thanks && Regards, Balasubramanian KumaranReply Denis Klimov October A full hour of crunching stopped becuase of a 0 on a single row.. 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 slightly slower Sql Nullif Function todd sharp Oct 3, 2007 at 10:45 PM 48 Comments Excellent find!

Sql Divide By Zero Error Nullif Typically, no one thinks to specify that nulls should be excluded.
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, http://darrenmanning.com/divide-by/divide-by-zero-error-in-ms-sql.html Note that it is always better to add a small explanation of whatever you are suggesting - even if it seems very simple ;) –Trinimon Sep 16 '15 at 16:42 add Lastly, using the SET ARITHABORT and SET ANSI_WARNINGS, your query will look like the following: SET ARITHABORT OFF SET ANSI_WARNINGS OFF SELECT [Numerator] / [Denominator] With both ARITHABORT and ANSI_WARNINGS set Or someone cloaned my code (that never happens, right?) and did not think about the warnings?

Good to know about NULLIF Oct 14, 2010 at 09:07 AM ozamora Håkan Winther Nope, the case statement is not any faster because NULLIF is the case statememt. If you're dividing by zero, you're trying to do something that doesn't make sense mathematically, so no numeric answer you can get will be valid.

Here is my test: -- test data create table dbo.IsnullAndNullifVersusCase ( col1 int not null identity(1, 1) primary key clustered, col2 int not null ); go this is painfully slow, but When you have to deal with billions of records in one query it could be important. I checked tables for integrity and no errors was found. Consider a situation in which 0 is bad and non-zero is good.
