Параметры

  • property
    The property on the principal end of the specified referential constraint.
  • refConstraint
    A referential constraint in a conceptual model.

Возвращаемое значение

The property on the dependent end of the specified referential constraint that corresponds to the property on the principal end.

Пример

Consider the following referential constraint that is defined in a conceptual model:

<ReferentialConstraint>
     <Principal Role="DiscontinuedProduct">
          <PropertyRef Name="ProductId" />
          <PropertyRef Name="ProductName" />
     </Principal>
     <Dependent Role="DiscontinuedItem">
          <PropertyRef Name="ItemId" />
          <PropertyRef Name="ItemName" />
     </Dependent>
</ReferentialConstraint>

If the ProductName property were passed to the GetDependentProperty method, the ItemName property would be returned.

Замечания

The GetDependentProperty method is used by the Generate Database Wizard when generating a database from a conceptual model.
