What's the difference?

And no, I'm not trying to be snotty, I really am wondering what's the difference, other than you are, essentially, returning a true/false and I'm returning an integer


>The first check should be

>select @RecExists = cast( case when exists (select 1 from TestResult where SCN = @SCN) then 1 else 0 end as bit)

>Also, I guess you want to declare this variable as bit if you only want to use it for test of existence.
