With this property set to false, a procedure will be called like "Proc(:param1, :param2)" or "Proc(:param2, :param1)" subject to parameters order. If true, the statement will be like "Proc(param2 => :param2, param1 => :param1)", thus result will be the same regardless of parameters order.
This property can be used with any value of the ParameterCheck property. Ignored if CommandType is other than CommandType.StoredProcedure.
