i am calculating Percentage it giving this error
Divide by zero error encountered.Warning: Null value is eliminated by an aggregate or other SET operation.

What I have tried:

i tried to used null but it is say isnull require to argument which i tried to adjust Like isnull(A,0) but not getting adjusted..
SQL

Some value is zero. Use the debugger to find out which.
MadMyche 2-Jul-19 14:40pm    
Agreed there is a zero somewhere; normally I'd troubleshoot but the code has too manny formatting (or lack thereof) issues
RedDk 2-Jul-19 16:11pm    
... arghhh! ... man, there's nothing more aggrevating than a poster editing his post without alerting the community participants to his edit. Now my code doesn't pass intellisense ...

[EDIT]
And lomac's headsup had nothing to do with the problem ... and I quit
[END EDIT]

If you want to avoid a division by zero error when using ISNULL then don't choose zero as the substitution for null in the divisor - use 1 instead (as division by 1 is the original value).

However, all of your val values must be null for SUM(val) to return null. We know that isn't the case so that isn't actually your underlying problem.

Look at
Bigbale_Weight + Small_Bale_weight
for secnam = M-Baby, M-HHR, m-HR etc … all zero. You are calculating percentage for all rows in the table

Change the calculation for percentage to handle that fact e.g.
SQL
--For Percentage--
CASE WHEN ISNULL(Bigbale_Weight,0) + ISNULL(Small_Bale_weight,0) <> 0 
    THEN (ISNULL(Small_Bale_weight,0) / ISNULL(Bigbale_Weight + Small_Bale_weight,1 )) * 100.0
    ELSE 0 END AS [Percentage],
Note the square brackets around "Percentage" - that's because it is a reserved word in SQL and shouldn't really be used as a column name (unless surrounded by [ ] ).

I've also simplified the calculation by removing SUM here but your use of the sub-query is arguably better as you wouldn't need the ISNULL I've used. However, I suspect my version is faster.

Finally, I'm upvoting your question because you gave us everything we needed to reproduce the problem - thank you!

An error message:
Quote:
it is say isnull require t(w)o argument(s)

is self explanatory.

BTW: [w] and [s] have been added by me to correct spellings.

Now, take a look at your code:
SQL
--For Percentage--
( Select (ISNULL(Small_Bale_weight,0))/(ISNULL(SELECT SUM(val)
FROM (VALUES (Bigbale_Weight),
(Small_Bale_weight )
)AS value(val)
))*100.0) as Percentage, ... -- comma and zero are missing

is this way? but still same issue
( Select (ISNULL(Small_Bale_weight,0))/(ISNULL(SELECT SUM(val)
FROM (VALUES (Bigbale_Weight),
(Small_Bale_weight ))AS value(val)
))*100.0,0)) as Percentage,
