Single developer app, so enforcement not so difficult except for my memory. :-) –Ron Savage May 14 '09 at 15:02 2 Despite the print statement, it's not a stored proc, So it would be: Percentage = ISNULL(100 * ClubTotal / NULLIF(AttTotal, 0), 0) The inner part is evaluated to NULL and then ISNULL replaces it with 0.

Making the initial query a subselect and then doing a GROUP BY on the outer query also changes the results because there is division involved. –Andrew Steitz Mar 1 '13 at Solution: There can be many ways to handle this error. Originally the question seemed to be phrased as "what can I do to just hide this error." Since then, it has evolved.

I should be reading in a radiation measurement scaling value, but in a strange edge case I didn't anticipate, I read in 0. This situation often arises in production databases if the script has not been tested with sufficient data before putting the script to production database.
Viewable by all users 0 In this particular situation, it looks like you want to divide by 1, but to skip rows with zero or NULL and if it is OK Are they lost forever? 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 Divide By Zero Error Encountered Sql Server 2008 Or someone cloaned my code (that never happens, right?) and did not think about the warnings?

If an arithmetic operator has two expressions of same type, the result has the same data type with the precision and scale defined for that concerned data type.Hence, applying BODMAS for http://www.sql-server-helper.com/error-messages/msg-8134.aspx The operation has to to throw, since the mathematical meaning of x/0 is different from the NULL meaning, so it cannot return NULL.
Now, 1/17 has a result of 0.0588235; Since both numerator and denominator are of type ‘int', having the scale of 0.
