Question : tuples in sql server

like in oracle syntax (and (a,b) not in (select x,y from query)), we do not have that in SS yet, do we?

NOT IN is the best alternative in SS, right?

thanks

Answer : tuples in sql server

For now, using NOT IN would be an efficient means.
There are possibly other ways, like turning the tuple into XML or a user defined type, but will not perform as fast.
