NULLIF requires two arguments. 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. Based on your request, here is another puzzle which is very similar to the earlier puzzle but have a very different approach.The question is why following T-SQL gives a famous divide I recommend you read this article: http://www.sqlmag.com/Articles/ArticleID/9148/pg/2/2.html share|improve this answer answered May 14 '09 at 15:49 Remus Rusanu 206k25267405 3 There is such a "Magic global setting";SET ARITHABORT OFF. –David
