NULLIF compares two expressions and returns null if they are equal or the first expression otherwise. It wont be a NULL as its coming from a dmv, the values are 0 to gabillions... I'm not sure I like it, but it might be useful to know of, some day. Msg 8134 Level 16 State 1 Line 1 Divide By Zero Error Encountered My dog ate the USB key with 10000 monero wallet.

To return a 0 value instead of a NULL value, you can put the division operation inside an ISNULL function: SET ARITHABORT OFF SET ANSI_WARNINGS OFF SELECT ISNULL([Numerator] / [Denominator], 0) I would rather signal to the user that the result is unknown because the divisor is zero. –Henrik Staun Poulsen Sep 17 '15 at 11:49 add a comment| up vote 1 more ▼ 0 total comments 973 characters / 178 words asked Oct 14, 2010 at 08:54 AM in Default Fatherjack ♦♦ 43.7k ● 79 ● 98 ● 117 edited Oct 14, check over here Let me know if you need more explanation on this.Secondly, we are performing,SELECT 10000/(17/17/17) AS Result2In short, it is an integer division, and we are dividing 10000/0 (as explained above).
