    select CustomerID, ContactTitle, CompanyName from customers  
else if(@shape = 2)  
    select OrderID, ShipName from orders  
[Function(Name="dbo.VariableResultShapes")]
[ResultType(typeof(VariableResultShapesResult1))]
[ResultType(typeof(VariableResultShapesResult2))]
public IMultipleResults VariableResultShapes([Parameter(DbType="Int")] System.Nullable<int> shape)
{
    IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), shape);
    return ((IMultipleResults)(result.ReturnValue));
}

ResultType(GetType(VariableResultShapesResult1)), _
ResultType(GetType(VariableResultShapesResult2))> _
Public Function VariableResultShapes(<Parameter(DbType:="Int")> ByVal shape As System.Nullable(Of Integer)) As IMultipleResults
    Dim result As IExecuteResult = Me.ExecuteMethodCall(Me, CType(MethodInfo.GetCurrentMethod, MethodInfo), shape)
    Return CType(result.ReturnValue, IMultipleResults)
End Function

Comentarios

En el siguiente ejemplo de código SQL, la forma del resultado depende de la entrada (shape =1 o shape = 2).In the following SQL code example, the result shape depends on the input (shape =1 or shape = 2). El orden en el que se devuelven las proyecciones es indefinido.The order that the projections are returned is undefined.
