Using Cube and Subcube Expressions
You often use cube and subcube expressions with Multidimensional Expressions (MDX) statements to define, manipulate, or retrieve data from a cube or subcube.
Cube Expressions
A cube expression contains either a cube identifier or the CURRENTCUBE keyword. Many MDX statements use the CURRENTCUBE keyword to identify the current cube context instead of requiring a cube identifier.
A cube identifier appears as Cube_Name.
SubCube Expressions
A subcube expression can contain a subcube identifier, a subcube function, or an MDX statement that returns a subcube. The MDX SELECT statement, for example, returns a subcube and can be used where subcube expressions are allowed.
A subcube identifier appears as Subcube_Name.
