Parameter

• child1
  Typ: Microsoft.SqlServer.Types.SqlHierarchyId
  The lower bound.

• child2
  Typ: Microsoft.SqlServer.Types.SqlHierarchyId
  The upper bound.

Rückgabewert

Typ: Microsoft.SqlServer.Types.SqlHierarchyId
A SqlHierarchyId with a value greater than the lower bound and less than the upper bound.

Hinweise

• If parent is nullein NULL-Verweis (Nothing in Visual Basic), returns nullein NULL-Verweis (Nothing in Visual Basic).

• If parent is not nullein NULL-Verweis (Nothing in Visual Basic), and both child1 and child2 are nullein NULL-Verweis (Nothing in Visual Basic), returns a descendant of parent.

• If parent and child1 are not nullein NULL-Verweis (Nothing in Visual Basic), and child2 is nullein NULL-Verweis (Nothing in Visual Basic), returns a descendant of parent greater than child1.

• If parent and child2 are not nullein NULL-Verweis (Nothing in Visual Basic) and child1 is nullein NULL-Verweis (Nothing in Visual Basic), returns a descendant of parent less than child2.

• If parent, child1, and child2 are not nullein NULL-Verweis (Nothing in Visual Basic), returns a descendant of parent greater than child1 and less than child2.

• An exception is raised if child1 or child2 are not nullein NULL-Verweis (Nothing in Visual Basic) and are not a descendant of parent.

• If child1 >= child2, an exception is raised.
