AllMembers (MDX)
Evaluates either a hierarchy or a level expression and returns a set that contains all members of the specified hierarchy or level, which includes all calculated members in the hierarchy or level.
Syntax
Hierarchy syntax
Hierarchy_Expression.AllMembers
Level syntax
Level_Expression.AllMembers
Arguments
Hierarchy_Expression
A valid Multidimensional Expressions (MDX) expression that returns a hierarchy.Level_Expression
A valid Multidimensional Expressions (MDX) expression that returns a level.
Remarks
The AllMembers function returns a set that contains all members, which includes calculated members, in the specified hierarchy or level. The AllMembers function returns the calculated members even if the specified hierarchy or level contains no visible members.
Important
When a dimension contains only a single visible hierarchy, the hierarchy can be either referred to by the dimension name or by the hierarchy name, because the dimension name in this case is resolved to its only visible hierarchy. For example, Measures.AllMembers is a valid MDX expression because it resolves to the only hierarchy in the Measures dimension.
Note
The AllMembers function is semantically similar to the AddCalculatedMembers (MDX) function.
Examples
The following example returns all members in the [Date].[Calendar Year] attribute hierarchy on the column axis, this includes calculated members, and the set of all children of the [Product].[Model Name] attribute hierarchy on the row axis from the Adventure Works cube.
SELECT
[Date].[Calendar Year].AllMembers ON COLUMNS,
[Product].[Model Name].Children ON ROWS
FROM
[Adventure Works]
The following example returns all members in the Measures dimension on the column axis, this includes all calculated members, and the set of all children of the [Product].[Model Name] attribute hierarchy on the row axis from the Adventure Works cube.
SELECT
Measures.AllMembers ON COLUMNS,
[Product].[Model Name].Children ON ROWS
FROM
