Divide by Zero Error

I would like to know if anyone has a work around divide by zero.

I have a view with calculations, which sometimes has a divide by zero error.

I know I can use the
SET ARITHABORT OFF
SET ANSI_WARNINGS OFF

To stop the error, but you cannot use these commands in a view.

I use my views as the backbone for my reports, I know I could work around this in Access or Crystal reports, but I would like the SQL server to do most of the work.

Any help would be appreciated

Thanks

Um, wouldn't it be

select col1 / case when col2 is null or col2 = 0 then 1 else col2 end

Or better - if no result is wanted for divide by zero, then return null

SELECT CASE WHEN col2 IS NULL OR col2 = 0 THEN NULL ELSE col1 / col2 END
