mysql 与或语句的sql查询问题

1. 只能使用嵌套查询了

select * from (select * from view_label_tab_campaign where ADOFFER_ID='7') as sea where sea.CAMPAIGN_ID like '%2%' or sea.CAMPAIGN_NAME like '%2%' ;

+---------------------+--------------+-------------+---------------+--------+------------+------------+

| CampListLabel      | CampLabel    | CAMPAIGN_ID | CAMPAIGN_NAME | STATUS | ADOFFER_ID | CHANNEL_ID |

+---------------------+--------------+-------------+---------------+--------+------------+------------+

| 8-ios|qdao22-enable | 8-ios|qdao22 |          8 | ios|qdao22    | enable |          7 |          3 |

+---------------------+--------------+-------------+---------------+--------+------------+------------+

2.

mysql> select * from view_label_tab_campaign where CAMPAIGN_ID like '%2%' or CAMPAIGN_NAME like '%2%' ;

+---------------------------+--------------------+-------------+-----------------+--------+------------+------------+

| CampListLabel            | CampLabel          | CAMPAIGN_ID | CAMPAIGN_NAME  | STATUS | ADOFFER_ID | CHANNEL_ID |

+---------------------------+--------------------+-------------+-----------------+--------+------------+------------+

| 2-ios|qudao-active        | 2-ios|qudao        |          2 | ios|qudao      | active |          1 |          1 |

| 8-ios|qdao22-enable      | 8-ios|qdao22      |          8 | ios|qdao22      | enable |          7 |          3 |

| 12-放置奇兵|PP助手-active | 12-放置奇兵|PP助手 |          12 | 放置奇兵|PP助手 | active |        13 |          7 |

+---------------------------+--------------------+-------------+-----------------+--------+------------+------------+

3 rows in set

3.

mysql> select * from view_label_tab_campaign where CAMPAIGN_ID like '%2%' or CAMPAIGN_NAME like '%2%' and ADOFFER_ID=1;

+---------------------------+--------------------+-------------+-----------------+--------+------------+------------+

| CampListLabel            | CampLabel          | CAMPAIGN_ID | CAMPAIGN_NAME  | STATUS | ADOFFER_ID | CHANNEL_ID |

+---------------------------+--------------------+-------------+-----------------+--------+------------+------------+

| 2-ios|qudao-active        | 2-ios|qudao        |          2 | ios|qudao      | active |          1 |          1 |

| 12-放置奇兵|PP助手-active | 12-放置奇兵|PP助手 |          12 | 放置奇兵|PP助手 | active |        13 |          7 |

+---------------------------+--------------------+-------------+-----------------+--------+------------+------------+

4. 解决方案是，将一组或语句使用小括号括起来，然后再和其他语句进行与操作！
