mysql 批量有则修改，无则新增

需要为表添加唯一索引
　　alter table tb_*** add unique index(aa,bb); -- 此条为联合唯一索引

INSERT INTO
<include refid="table_name" />
(
<include refid="Base_Column_List" />
)
VALUES
<foreach collection="list" item="item" index="index"  separator=",">
    (
    <include refid="Base_Column_value_item" />
    )
</foreach>

ON DUPLICATE KEY UPDATE user_name=user_name+VALUES(user_name)
