Set Operators

In Multidimensional Expressions (MDX), set operators perform operations on members or sets, and return a set. You often use set operators as an alternate to several set functions in MDX expressions.

MDX supports the set operators listed in the following table.

Operator	Description
- (Except)	Returns the difference between two sets, removing duplicate members. This operator is functionally equivalent to the Except function.
* (Crossjoin)	Returns the cross product of two sets. This operator is functionally equivalent to the Crossjoin function.
: (Range)	Returns a naturally ordered set, with the two specified members as endpoints and all members between the two specified members included as members of the set.
+ (Union)	Returns a union of two sets, excluding duplicate members. This operator is functionally equivalent to the Union (MDX) function.
