SQL Server 2008 R2


  This feature will be removed in the next version of Microsoft SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible.

An object of the ClassType clsCubeRole provides a specific implementation of the Decision Support Objects (DSO) Role interface. This object provides collections, methods, and properties through the Role interface.

You use objects of ClassType clsCubeRole to manage the set of users who can access a cube (of any type) and the manner in which they can access it. A cube role has a name, a description, a parent object, a class type, a list of users, and a set of permissions. Each permission has a key and a corresponding permission expression.

You create roles at the database level (database roles) and then assign them to cubes (cube roles) by adding them to the collection of roles associated with the cube. The roles assigned to a cube automatically apply to its partitions and aggregations.

You can remove a database role by removing it from the database's collection of role objects. When you do so, the system automatically removes the corresponding cube roles from the cube's collection of role objects.

You can remove a cube role by removing it from the cube's collection of role objects. When you do so, the corresponding database role is not affected. However, the definition of the cube role remains in effect until you update or process the cube.

Suppose you want to define roles named FinanceManagers, ProductionManagers, and SalesManagers at the database level. Suppose also that you want to assign the appropriate vice-president to the list of users for each role and the company president to the list of users for all three roles. Finally, suppose that you want to create a cube for each year's financial, production, and sales data for the years 1995, 1996, and 1997.

Use the following code to define the appropriate database and cube roles for this situation.


  User lists defined for database roles are automatically associated with the corresponding cube roles and cannot be changed at the cube role level.

'Assume an object (dsoDB) of ClassType clsDatabase exists.
'Create database roles.
Dim DbRole_FinanceMgrs As DSO.Role
Dim DbRole_ProductionMgrs As DSO.Role
Dim DbRole_SalesMgrs As DSO.Role
Set DbRole_FinanceMgrs = dsoDB.Roles.AddNew("FinanceManagers")
Set DbRole_ProductionMgrs = dsoDB.Roles.AddNew("ProductionManagers")
Set SbRole_SalesMgrs = dsoDB.Roles.AddNew("SalesManagers")

'Define user lists for database roles.
'(In a real-world situation, actual user names would be
'used in place of titles like "President".)
DbRole_FinanceMgrs.UsersList = "President;VP_Finance"
DbRole_ProductionMgrs.UsersList = "President;VP_Production"
DbRole_SalesMgrs.UsersList = "President;VP_Sales"

'Update the repository for the database roles.

'Assume objects (Cube95, Cube96 and Cube97) of ClassType clsCube exist
'Create cube roles. Cube role names must be identical
'to the corresponding database role names.
Dim CubeRole_FinanceMgrs As DSO.Role
Dim CubeRole_ProductionMgrs As DSO.Role
Dim CubeRole_SalesMgrs As DSO.Role

'Add roles to Cube95.
Set CubeRole_FinanceMgrs = Cube95.Roles.AddNew("FinanceManagers")
Set CubeRole_ProductionMgrs = Cube95.Roles.AddNew("ProductionManagers")
Set CubeRole_SalesMgrs = Cube95.Roles.AddNew("SalesManagers")

'Add roles to Cube96.
Set CubeRole_FinanceMgrs = Cube96.Roles.AddNew("FinanceManagers")
Set CubeRole_ProductionMgrs = Cube96.Roles.AddNew("ProductionManagers")
Set CubeRole_SalesMgrs = Cube96.Roles.AddNew("SalesManagers")

'Add roles to Cube97.
Set CubeRole_FinanceMgrs = Cube97.Roles.AddNew("FinanceManagers")
Set CubeRole_ProductionMgrs = Cube97.Roles.AddNew("ProductionManagers")
Set CubeRole_SalesMgrs = Cube97.Roles.AddNew("SalesManagers")

'Update the repository for the cubes.
