In T-SQL what’s faster?

DELETE * FROM ... WHERE A IN (x,y,z)

Or

DELETE * FROM ... WHERE A = x OR A = y OR A = z

In my case x, y and z are input parameters for the stored procedure. And I’m trying to get the performance of my DELETE and INSERT statements to the best of my abilities.

    “IN” will be translated to a series of “OR”s…if you look at the execution plan for a query with “IN”, you’ll see it has expanded it out.

    Much cleaner to use “IN” in my opinion, especially in larger queries it makes it much more readable.
