CurrentMember (MDX)
Returns the current member along a specified hierarchy during iteration.
Syntax
Hierarchy_Expression.CurrentMember
Arguments
Hierarchy_Expression
A valid Multidimensional Expressions (MDX) expression that returns a hierarchy.
Remarks
When iterating through a set of hierarchy members, at each step in the iteration, the member being operated upon is the current member. The CurrentMember function returns that member.
Important
When a dimension contains only a single visible hierarchy, the hierarchy can be referred to either by the dimension name or by the hierarchy name, because the dimension name is resolved to its only visible hierarchy. For example, Measures.CurrentMember is a valid MDX expression because it resolves to the only hierarchy in the Measures dimension.
Examples
The following query shows how Currentmember can be used to find the current member from hierarchies on the Columns, Rows and slice axis:
WITH
MEMBER MEASURES.CURRENTDATE AS [Date].[Calendar].CURRENTMEMBER.NAME
MEMBER MEASURES.CURRENTPRODUCT AS [Product].[Product Categories].CURRENTMEMBER.NAME
MEMBER MEASURES.CURRENTMEASURE AS MEASURES.CURRENTMEMBER.NAME
MEMBER MEASURES.CURRENTCUSTOMER AS [Customer].[Customer Geography].CURRENTMEMBER.NAME
SELECT
[Product].[Product Categories].[Category].MEMBERS *
{MEASURES.CURRENTDATE,
MEASURES.CURRENTPRODUCT,
MEASURES.CURRENTMEASURE,
MEASURES.CURRENTCUSTOMER} ON 0,
[Date].[Calendar].MEMBERS ON 1
FROM [Adventure Works]
WHERE ([Customer].[Customer Geography].[Country].&[Australia])
The current member changes on a hierarchy used on an axis in a query. Therefore, the current member on other hierarchies on the same dimension that are not used on an axis can also change; this behavior is called 'auto-exists' and more details can be found in Key Concepts in MDX (Analysis Services). For example, the query below shows how the current member on the Calendar Year hierarchy of the Date dimension changes with the current member on the Calendar hierarchy, when the latter is displayed on the Rows axis:
WITH
MEMBER MEASURES.CURRENTYEAR AS [Date].[Calendar Year].CURRENTMEMBER.NAME
SELECT
{MEASURES.CURRENTYEAR} ON 0,
[Date].[Calendar].MEMBERS ON 1
FROM [Adventure Works]
CurrentMember is very important for making calculations aware of the context of the query they are being used in. The following example returns the order quantity of each product and the percentage of order quantities by category and model, from the Adventure Works cube. The CurrentMember function identifies the product whose order quantity is to be used during calculation.
WITH
MEMBER [Measures].[Order Percent by Category] AS
CoalesceEmpty
(
([Product].[Product Categories].CurrentMember,
Measures.[Order Quantity]) /
(
Ancestor
( [Product].[Product Categories].CurrentMember,
[Product].[Product Categories].[Category]
), Measures.[Order Quantity]
), 0
), FORMAT_STRING='Percent'
SELECT
{Measures.[Order Quantity],
[Measures].[Order Percent by Category]} ON COLUMNS,
{[Product].[Product].Members} ON ROWS
FROM [Adventure Works]
WHERE {[Date].[Calendar Year].[Calendar Year].&[2003]}
