I have below query, which is giving error of Msg 8134, Level 16, State 1, Line 1
Divide by zero error encountered.
I think due to null value ,it is generating error, please guide me how to resolve it

Answer 1

You need to put NULLIF function to all expressions that use /, not into only some of them. You can see, for example:

cast((Small_Bale_weight1+Small_Bale_weight2)*100.0/(sum(Total_Weight2+Total_Weight)over(PARTITION BY (1) ))AS numeric(10,2))as SBPerTotal ,

it should be changed to

cast((Small_Bale_weight1+Small_Bale_weight2)*100.0/NULLIF(sum(Total_Weight2+Total_Weight),0) over(PARTITION BY (1) ))AS numeric(10,2))as SBPerTotal ,

Also, it may help to move SUM(TotalWeight) OVER () -- no need to partition into a separate CROSS APPLY

e.g.
CROSS APPLY (select NULLIF(sum(TotalWeight),0) over() as AllTotalWeight, NULLIF(sum(TotalWeight2),0) over() as AllTotalWeight2) X and use these two expressions. Also, I haven't tested the exact syntax, it may be that you need to put NULLIF for the whole expression.

Answer 2

Hi，@Analyst_SQL

There are three ways to deal with this situation. The first is to use the NULLIF function. The second is to set ARITHABORT off.
You can use this：

SET ARITHABORT OFF   
SET ANSI_WARNINGS OFF

The third is to use case when to avoid errors.According to your code, it may be The problem is that the sum of the Total_Weight+Total_Weight2 partition may be 0. You can try to modify it according to naomi's method. If an error occurs, please provide us with some test data, and we can help you calculate it.

Divide by zero error encountered.

A pretty clear error message, isn't it?

I think due to null value

No, not by NULL but by 0 = zero, as the error message say.

please guide me how to resolve it

Use a CASE condition to avoid divison by zero, like

... case when divider = 0 then null else value / divider end as Result
