Ibatis selectKey 返回值为空

 一个小问题，挺卡脸的

<!--添加-->

    <insert id="InsertOne" parameterclass="C_1211DotNetA" resultclass="int">

      insert into DotNetA

      (Name,

        Tel,

        HomePhone,

        Market,

        DormCode

       )

      values

      (#Name#,

        #Tel#,

       #HomePhone#,

       #Market#,

       #DormCode#

       )

      <selectkey resultClass="int" type="post" property="ID">

              SELECT @@IDENTITY AS value

     </selectkey>

    </insert>

   <selectKey></selectKey>  K要大写！！！！！

XML好像有的标签注重大小写有的不注重
