I used to use CASE statements in the divisor. 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 Leave new 亂馬客 December 29, 2014 7:06 amInt / int = int 17/17 => 1 1/17 => 0 10000/0 => Divide by zero error encountered. In some cases when using statistics functions, 0 or even 1 is an acceptable result when divisor is zero. –Athafoud Feb 3 at 8:26 3 Doing hacks like this has
ANSWER: I think there's an underlying issue here, which is that division by 0 is not legal. I am shocked that this gets 71 upvotes! 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 The results show that the overhead of using isnull + nullif is very small.
Now, 1/17 has a result of 0.0588235; Since both numerator and denominator are of type ‘int', having the scale of 0. ELSE ... What precisely differentiates Computer Science from Mathematics in theoretical context? This situation often arises in production databases if the script has not been tested with sufficient data before putting the script to production database.
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 I could do either of the following: Add a where clause so that my divisor is never zero Or I could add a case statement, so that there is a special This yields an infinite number of turns.
