Inheritance Validation

Inheritance Validation

You can create two types of inheritance relationship with XML views:
  • View-to-view inheritance.
    A view is a derived type of another view. Both views must have global complex view roots.
    A view can have an inheritance relationship to another view if its view root is a complex type derived from the view root type of the other view.
    A view can be a parent in multiple inheritance relationships, but a view can be a child in just one inheritance relationship.
  • Column-to-view inheritance.
    The column is an element of a local complex type, Type1, and the view is rooted at a global complex type, Type2. Type1 is derived from Type2.
    A column in a view can have an inheritance relationship to another view if the column is a local complex type and the type is derived from the view root type of the other view.
    If a column in a view, V1, has an inheritance relationship to a view, V2, you cannot put the content of V2 into view V1.
