我有一个使用 Entity framework 6和Mysql Database 的c＃应用程序。我添加了这个存储过程：
DELIMITER $$

DELIMITER ;
当我添加一个新的EF模型时，在上下文中我得到了这个mappage：
public virtual int ps_reservation(string id_compte)
{
var id_compteParameter = id_compte != null ?
new ObjectParameter("id_compte", id_compte) :
new ObjectParameter("id_compte", typeof(string));
return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction("ps_reservation", id_compteParameter);
}
我不明白为什么我会获得此方法签名：
public virtual int ps_reservation（string id_compte）
我的意思是为什么返回类型是整数!!为什么不是ObjectResult<ps_reservation_Result>？
