My thoughts are that the error message is 100% accurate. But what is your question?

I agree with Phil. 0 / 0 = [Insert infinite options here] = SQL server error is correct. 🙂

Hi friends,

I understand when bargain=100.0000, I get the divide by zero error. But when bargain =0.0000 and serno=7.90, the result should be 7.9 and I need to use the same logic (serno * 100) / (100 - bargain) for all the records..
Please help..

Thanks a lot again

What should be the result of the divide by 0?

Is there a way to exclude those records that divide by zero in the SQL and do the calculation only for those records that is not zero in the divide by clause.. Thanks

You would use a where clause to exclude records. In your case add:
WHERE serno > 0
after the from clause.

Edit: - Oops, didn't pay enough attention to the table and mixed up you columns. See responses below.

Use a case statement to check whether bargain = 100 and only do the division if it's not.

Of course, add
WHERE BARGAIN <> 100
to the bottom of your query.

There is a third option. I don't have the time right now to do a comparison.

select (serno * 100) / NULLIF(100 - bargain, 0) from yachtm
