关于一个SqlMap中Mysql语句的一个问题


  <select id="getU" parameterClass="U" resultClass="U">
        SELECT 
            A.usr_id as usrId
        FROM 
            U A
        WHERE 
            A.login_name=#loginName#
            AND A.login_pwd=#loginPwd#
            AND A.del_flg!=1
            AND A.ban_time IS NULL
    </select>
我直接执行这条Mysql语句是成功的
然后程序跑的时候报错：
com.ibatis.common.jdbc.exception.NestedSQLException:
