To the person who added NULLIF function to MSSQL I say I hope rabid ferrets bite your balls off.
That is all.

I did not use it but I find it helpful in some cases, given the one they mentioned in their docs for example

@gitpush there's cases where it can be useful, but it's kind of like triggers, there's a huge downside so yeah, sometimes you have to use it because there's no other way, but it doesn't mean it's good.
In this case it's not performance that's terrible with it but readability. Especially when combined with ISNULL... When I see those two on the same screen I just want to pour gasoline all over and light a match

@Bikonja now I understand, ya it is a pain having both on same line it gets confusing :/
