So Edwardo asks in the comments "what if the user puts in a 0?", and he advocates that it should be okay to get a 0 in return. Then to return a value of 0 instead of a NULL value, the ISNULL function is used. Enjoyed This? Can 'it' be used to refer to a person?

Whenever you encounter a divide by 0 you should ponder if the data should had been NULL instead of 0. –Remus Rusanu May 14 '09 at 18:34 30 I can't I think COALESCE() is more standard than ISNULL(). T Sql Avoid Divide By Zero
My average inventory is now 0. This example does not return an error message for these errors because ARITHIGNORE is OFF. Is there better way, or how can this be enforced? useful reference Some of my answer was addressed to concerns like that of Edwardo, in the comments, who seemed to be advocating returning a 0.
Is the best way to use a NullIf clause? The annual rate of sales is $4,000 ($1,000/3)*12. Reflection of "Yada yada hi dharmasya..." in Durga Saptashati? Divide By Zero Error Java 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.
ANSWER: I think there's an underlying issue here, which is that division by 0 is not legal. Here's the simple function that I wrote. Minecraft commands CanPlaceOn - Granite Help! this page NULLIF requires two arguments.

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. And how do you enforce it's use? Even if you write your query differently using ISNULL or NULLIF at the end it will likely execute the same. –Nenad Zivkovic Oct 28 '13 at 9:34 As has

The default is 0, so that's why it didn't work for me at first. Why don't you connect unused hot and neutral wires to "complete the circuit"?
It worked, but it was just wordy and distracting. 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. when I fill this form and submit. After you have the annualized number, you divide by the average inventory for the period.

Everybody who's used SQL for any amount of time knows that we can use a CASE expression to prevent division by zero. Humans as batteries; how useful would they be?
If the value of AttTotal or ClubTotal are NULL this will now also return 0. –Martin Smith Oct 28 '13 at 9:25 1 Agree, I like the one by @Dommer, The results show that the overhead of using isnull + nullif is very small. If you need otherwise, then you may want to wrap the equation in an ISNULL, to return a different value.
