ibatis.net：第四天，Update 和 Delete

xml

     <update id="UpdateOrder" parameterClass="Order">
       UPDATE [Orders] SET Customer = #Customer# WHERE Id = #Id#
     </update>
     <delete id="DeleteOrder" parameterClass="Order">
       DELETE FROM [Orders] WHERE Id = #Id#
     </delete>

代码

         public static void UpdateOrder()
         {
             var mapper = Mapper.Instance();

             var order = new Order
             {
                 Customer = "段光伟"
             };
             mapper.Insert("InsertOrder", order);
             Console.WriteLine(mapper.Update("UpdateOrder", order));
             Console.WriteLine(mapper.Delete("DeleteOrder", order));
         }

备注

Update 和 Delete 都返回受影响的行数。有一个需要重点考虑的是：乐观并发处理，框架好像并没有给予支持，估计需要我们自己处理（后面单独找一篇文章看看）。
