Paramètres

• oldRoot
  Type : Microsoft.SqlServer.Types.SqlHierarchyId
  An ancestor of the SqlHierarchyId node specifying the endpoint of the path segment that is to be moved.

• newRoot
  Type : Microsoft.SqlServer.Types.SqlHierarchyId
  The SqlHierarchyId node that represents the new ancestor of this.

Valeur de retour

Type : Microsoft.SqlServer.Types.SqlHierarchyId
A SqlHierarchyId node representing the new hierarchical location of this. Will return nullune référence Null (Nothing dans Visual Basic) if oldRoot, newRoot, or thisare nullune référence Null (Nothing dans Visual Basic).

Notes

Returns a node whose path from the root is the path to newRoot, followed by the path from oldRoot to this.

The SqlHierarchyId data type represents but does not enforce the hierarchical structure. Users must ensure that the SqlHierarchyId node is appropriately structured for the new location.
