Switch Showplan Operator

Switch is a special type of concatenation iterator that has n inputs. An expression is associated with each Switch operator. Depending on the return value of the expression (between 0 and n-1), Switch copies the appropriate input stream to the output stream.

One use of Switch is to implement query plans involving fast forward cursors with certain operators such as the TOP operator.

Switch is both a logical and physical operator.
