Updates an existing calculated member.

UPDATE MEMBER Cube_Name.Member_Name 
   AS MDX_Expression
      [,Property_Name = Property_Value, ...n]


A valid string that specifies the name of the cube that contains the member.


A valid string that specifies the name of an existing member.


A valid Multidimensional Expressions (MDX) expression to which the member is to be updated.


A valid string that specifies the name of a calculated member property.


A valid scalar expression that specifies the property value for the calculated member.

The UPDATE MEMBER statement updates an existing calculated member while preserving the relative precedence of this member with respect to other calculations. Therefore, you cannot use the UPDATE MEMBER statement to change SOLVEORDER.

An UPDATE MEMBER statement cannot be specified in the MDX script for a cube.

Specifying a cube other than the cube that is currently connected causes an error. Therefore, you should use CURRENTCUBE in place of a cube name to denote the current cube.

For more information about member properties that are defined by OLE DB, see the OLE DB documentation.

Each member has a set of default properties. The following table lists those default properties.

Property identifier



A Microsoft Office style format string that the client application can use to display cell values.


A value that indicates whether the calculated member is visible in a schema rowset. Visible calculated members can be added to a set with the AddCalculatedMembers function. A nonzero value indicates that the calculated member is visible. The default value for this property is Visible.

Calculated members that are not visible are generally used as intermediate steps in more complex calculated members. These calculated members can also be referred to by other types of members, such as measures.


The measure or set that MDX uses to determine the behavior of calculated members when resolving empty cells.


A string value that specifies the caption that the client application uses to display the member.


A string value that specifies the path of the display folder where the member is to be shown by the client application. The folder level separator is defined by the client application. For the tools and clients supplied by Analysis Services, the backslash (\) as the level separator. To provide multiple display folders for a defined member, use a semicolon (;) to separate the folders.


The name of the measure group to which this member is associated.
