By automatically letting 0 be the default for nulls you are introducing potentially quite significant bias into your data sets.So, without labouring the point, I recommend that you reconsider this last Therefore, running the above code, we get the following output:[ 0 ]As someone who runs a ton of reports on database table (albeit, not in any educated way), this is going So, instead of: WHERE col1 > 0 AND col2 / col1 > 0.1 Use: WHERE CASE WHEN col1 <= 0 THEN 'No' WHEN col2 / col1 > 0.1 THEN 'Yes' ELSE First, here's the usual case statement. http://stackoverflow.com/questions/861778/how-to-avoid-the-divide-by-zero-error-in-sql
This is what I mean by shortcut is *allowed* (amd, again, anything else would be stupid). Causes: This error is caused by performing a division operation wherein the denominator or the divisor is 0. NULLIF compares two expressions and returns null if they are equal or the first expression otherwise.
Not the answer you're looking for? In this case, as they both are equal its returning null. Or any other number :-) Returning zero implies ClubTotal is zero and AttTotal is more than zero. –Tom Chantler Oct 28 '13 at 9:38 add a comment| up vote 6 down Tsql Divide By Zero Error Encountered Msg 8134, Level 16, State 1, Line 2 To avoid this I am using a CASE as: DECLARE @Int1 AS INT , @Int2 AS INT SET @Int1 = 6 SET @Int2

Replace the variable @Int2 from the original question with a subquery (just a call to RAND for compactness): SELECT1 / ISNULL(NULLIF((SELECT FLOOR(RAND() * 2)),0),1); That will frequently give a divide by Divide By Zero Error Encountered Excel 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. Not sure about ISNULL().

At least Oracle's implementation of NULLIF doesn't accept NULL value as valid parameter and returns error message about it.So, in complete form it looks like:nullif(nvl(divisor,0),0)NVL will change NULL on 0 and To return a 0 value instead of a NULL value, you could still put the division operation inside the ISNULL function:SET ARITHABORT OFFSET ANSI_WARNINGS OFFSELECT ISNULL([Numerator] / [Denominator], 0)Just one more Wish I would have known about this a long time ago - I've always just used a case statement:case when isNull(divisor, 0) = 0 then 0 else numerator/divisor end as valueBut useful reference I am shocked that this gets 71 upvotes!
After programming the current time, you set the times you want them to eat, THEN go back to those times and select 1 rotation or 2, depending on how much you Oracle Sql Divide By Zero Guild Companies, Inc., 50 Park Terrace East, Suite 8F, New York, NY 10034 Privacy Statement Imagine: WHERE c1 = 23 and c2 = 45 Also, imagine an index on c1.
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. Hurray, no radiation! I find that in most cases, having a zero is graphically equivalent to NULL and a whole lot easier to deal with.
