參數

• parent
  型別：Microsoft.SqlServer.Types.SqlHierarchyId
  The specified SqlHierarchyId node for which the IsDescendantOf test is performed.

傳回值

型別：System.Data.SqlTypes.SqlBoolean
Boolean , true (1) for all the nodes in the sub-tree rooted at parent; false (0) for all other nodes.

備註

parent is considered its own descendant.
