Using the NULLIF and ISNULL functions, your query will look like the following: SELECT ISNULL([Numerator] / NULLIF([Denominator], 0), 0) AS [Percentage] FROM [Table1] What this does is change the denominator into The content you requested has been removed. But, just a guess. But encountering the nulls prompts the question. http://darrenmanning.com/divide-by/divide-by-zero-error-in-sql-2008.html

I've only done this for simple queries, so I don't know how it will affect longer/complex ones. Is the best way to use a NullIf clause?
Returning a null, the answer he eventually comes to, seems like one reasonable reponse. (I was strongly advocating not returning a 0, or some other number.) –Beska Mar 14 '13 at I find that in most cases, having a zero is graphically equivalent to NULL and a whole lot easier to deal with. share|improve this answer answered Aug 25 '09 at 22:10 finnw 32k1398176 I start to like CHECK constraints more and more. –Henrik Staun Poulsen Aug 16 '10 at 18:05 add Tsql Divide By Zero Error Encountered All Rights Reserved current community blog chat Database Administrators Database Administrators Meta your communities Sign up or log in to customize your list.
please help me out.

The annual rate of sales is $4,000 ($1,000/3)*12. The reason is that SQL Server evaluates the source expression twice when it expands NULLIF into the equivalent CASE expression.

So the most elegant way to overcome this is to use NULLIF function and compare @iter to zero. http://darrenmanning.com/divide-by/divide-by-zero-error-encountered-sql-2008.html Rather than calculating something you state the value to return for the case that AttTotal is zero. DECLARE @iter FLOAT; DECLARE @num FLOAT; SET @num = 10; SET @iter = 5; WHILE @iter > -5 BEGIN SELECT ISNULL(@num / NULLIF(@iter,0),@num); SET @iter = @iter I assume you are taking care of the obvious and your queries have conditions that should eliminate the records with the 0 divisor and never evaluate the division.

Oct 14, 2010 at 11:42 AM Håkan Winther I generally use this for percentages where zero is required. select itnbr, Amount, Quantity, Amount / nullif(Quantity,0) from SomeTable If Quantity is not zero, the two arguments do not match, and the resulting calculation is Amount divided by Quantity.

Are they lost forever? This is completely wrong in a mathematical sense, and it is even dangerous as your application will likely return wrong and misleading results. 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 ELSE ...
When it does equal zero, it will instead change it to a null.

This documentation is archived and is not being maintained. I should be reading in a radiation measurement scaling value, but in a strange edge case I didn't anticipate, I read in 0. The beginning inventory is 0. You could even add another case branch for 0 of 0 being 100%.
