Crossjoin
Returns the cross product of two sets.
Syntax
Crossjoin(«Set1», «Set2»)
Alternate Syntax
«Set1» * «Set2»
Note This alternate syntax is a Microsoft® SQL Server™ 2000 Analysis Services extension to Multidimensional Expressions (MDX) in OLE DB 2.0 and later.
Remarks
The order of tuples in the resulting set depends on the order of «Set1» and «Set2» and the order of their members.
If «Set1» = {x1, x2,...,xn} and «Set2» = {y1, y2, ..., yn}, then Crossjoin(Set1, Set2) is:
{(x1, y1), (x1, y2),...,(x1, yn), (x2, y1), (x2, y2),...,
(x2, yn),..., (xn, y1), (xn, y2),..., (xn, yn)}
Example
The following example returns {([1994], USA), ([1994], Japan), ([1995], USA), ([1995], Japan)}:
CrossJoin({[1994], [1995]}, {USA, Japan})
