web项目在我添加计算字段后打不开了，还原后报错，我导入之前备份的还是这样错误，帮忙看下吧

提示错误如下==> Preparing: select count(0) from (select a.NAME, a.Y_ID, a.QR_ID, a.PHONE, a.SHEQU, a.ADDIN, a.USE_FLAG, a.IC_ID, a.BAG_NUM1, a.BAGN_UM2, a.BAGN_UM3, a.BAG_NUM_SET, a.EMAIL, a.JIFEN, a.HUANBAOFENG, a.TIME, a.TYPE, a.YEZHU_ID from TB_YEZHU a where 1=1 and SHEQU = ? order by TIME desc,JIFEN desc) tmp_count 2016-10-25 10:18:45 -29964 [http-8080-2] DEBUG - {conn-10001, pstmt-20001} enter cache 2016-10-25 10:18:45 -29965 [http-8080-2] ERROR - org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.type.TypeException: JDBC requires that the JdbcType must be specified for all nullable parameters.

总是提示上面的错误，我贴出出现错误的sql语句：
<!-- 列表 -->

a.NAME,
a.Y_ID,
a.QR_ID,
a.PHONE,
a.SHEQU,
a.ADDIN,

        and
            (

                 or 
                 a.Y_ID LIKE CONCAT(CONCAT('%', #{pd.SEARCHKEY}),'%')
                 or
                 a.PHONE LIKE CONCAT(CONCAT('%', #{pd.SEARCHKEY}),'%')
                 or
                 a.ADDIN LIKE CONCAT(CONCAT('%', #{pd.SEARCHKEY}),'%')
                 or
                 a.NAME LIKE CONCAT(CONCAT('%', #{pd.SEARCHKEY}),'%')
            )
    </if>

        order by TIME desc,JIFEN desc

你的模糊查询为什么使用两个concat
