LookupCube (MDX)

SQL Server 2012

Returns the value of a Multidimensional Expressions (MDX) expression evaluated over another specified cube in the same database.

Syntax


          

Numeric expression syntax
LookupCube(Cube_Name, Numeric_Expression )

String expression syntax
LookupCube(Cube_Name, String_Expression )

Arguments

Cube_Name: A valid string expression that specifies the name of a cube.
Numeric_Expression: A valid numeric expression that is typically a Multidimensional Expressions (MDX) expression of cell coordinates that return a number.
String_Expression: A valid string expression that is typically a valid Multidimensional Expressions (MDX) expression of cell coordinates that returns a string.

Remarks

If a numeric expression is specified, the LookupCube function evaluates the specified numeric expression in the specified cube and returns the resulting numeric value.

If a string expression is specified, the LookupCube function evaluates the specified string expression in the specified cube and returns the resulting string value.

The LookupCube function works on cubes within the same database as the source cube on which the MDX query that contains the LookupCube function is running.

Important
You must provide any necessary current members in the numeric or string expression because the context of the current query does not carry over to the cube being queried.

Any calculation using the LookupCube function is likely to suffer from poor performance. Instead of using this function, consider redesigning your solution so that all of the data you need is present in one cube.

Examples

The following query demonstrates the use of LookupCube:

WITH MEMBER MEASURES.LOOKUPCUBEDEMO AS

LOOKUPCUBE("Adventure Works", "[Measures].[In" + "ternet Sales Amount]")

SELECT MEASURES.LOOKUPCUBEDEMO ON 0

FROM [Adventure Works]
