mybatis查询错误

mybatis查询报错

代码如下

Page queryRulePage(@Param("TestVo")TestVo testVo,@Param("sql") String sql);

<select id="queryRulePage" resultMap="BaseResultMap" parameterType="com.po.Test">
    select <include refid="Base_Column_List" />
    from test where  ${sql}
 <if test="sentflag != null and sentflag != ''">
      and sentflag = #{sentflag}
    if>
 select>

Caused by: org.apache.ibatis.binding.BindingException: Parameter 'sentflag' not found. Available parameters are [testVo, param1, sql, param2]

报错没有传sentflag字段吧
