Oh come on, it'll have an effect. You're inserts will be faster because you're not maintaining a useless index.

I definately recommend you NOT use a function for this type of query. It's a straight select statement. It should be done within a stored procedure or a parameterized query....

The function is probably presenting itself as (doing this from memory, so forgive me if I'm slightly off) a table scan or an external operation, but I think if you...

I suspect, but this is a guess, you're getting an index scan and then a bookmark lookup to get to the data and then...
