sphinx也就是一个像mysql数据库的工具了,我们可以在linux中使用sphinx来替换mysql了,下面小编整理了几个sphinx联合查询的语句,记得以前sphinx是不支持联合查询的,第一次接触sphinx,好像2010年初的时候,当时写过一篇关于sphinx安装的文章,sphinx mmseg mysql 中文分词,下面举例说明,sphinx的联合查询用法.
一,添加二张测试表和数据,代码如下:
1,users表和数据
- mysql> desc users;
- +----------+-------------+------+-----+---------+----------------+
- | Field | Type | Null | Key | Default | Extra |
- +----------+-------------+------+-----+---------+----------------+
- | user_id | int(11) | NO | PRI | NULL | auto_increment |
- | username | varchar(20) | NO | | NULL | |
- +----------+-------------+------+-----+---------+----------------+
- 2 rows in set (0.00 sec)
- --phpfensi.com
- mysql> select * from users;
- +------------+------------+
- | user_id | username |
- +------------+------------+
- | 1311895262 | 张三 |
- | 1311895263 | tank张二 |
- | 1311895264 | tank张一 |
- | 1311895265 | tank张 |
- +------------+------------+
- 4 rows in set (0.00 sec)
2,orders表和数据
- mysql> desc orders;
- +--------------+-------------+------+-----+---------+----------------+
- | Field | Type | Null | Key | Default | Extra |
- +--------------+-------------+------+-----+---------+----------------+
- | id | int(11) | NO | PRI | NULL | auto_increment |
- | user_id | int(11) | NO | | NULL | |
- | create_time | datetime | NO | | NULL | |
- | product_name | varchar(20) | NO | | NULL | |
- | summary | text | NO | | NULL | |
- +--------------+-------------+------+-----+---------+----------------+
- 5 rows in set (0.00 sec)
- mysql> select * from orders;
- +----+------------+---------------------+----------------+--------------+
- | id | user_id | create_time | product_name | summary |
- +----+------------+---------------------+----------------+--------------+
- | 9 | 1311895262 | 2014-08-01 00:24:54 | tank is 坦克 | 技术总监 |
- | 10 | 1311895263 | 2014-08-01 00:24:54 | tank is 坦克 | 技术经理 |
- | 11 | 1311895264 | 2014-08-01 00:24:54 | tank is 坦克 | DNB经理 |
- | 12 | 1311895265 | 2014-08-01 00:24:54 | tank is 坦克 | 运维总监 |
- +----+------------+---------------------+----------------+--------------+
- 4 rows in set (0.00 sec)
二,配置sphinx.conf,代码如下:
- source order
- {
- type = mysql
- sql_host = localhost
- sql_user = root
- sql_pass =
- sql_db = test
- sql_query_pre = SET NAMES utf8
- sql_query = \
- SELECT a.id, a.user_id,b.username, UNIX_TIMESTAMP(a.create_time) AS create_time, a.product_name, a.summary \
- FROM orders a left join users b on a.user_id = b.user_id
- sql_attr_uint = user_id
- sql_field_string = username
- sql_field_string = product_name
- sql_attr_timestamp = create_time
- sql_ranged_throttle = 0
- sql_query_info = SELECT * FROM orders WHERE id=$id
- }
- index myorder
- {
- source = order
- path = /usr/local/sphinx/var/data/myorder
- docinfo = extern
- mlock = 0
- morphology = none
- min_word_len = 1
- charset_dictpath = /usr/local/mmseg3/etc/
- charset_type = zh_cn.utf-8
- ngram_len = 0
- html_strip = 0
- }
注意:在这里a.user_id = b.user_id,等号二边一定要有空格,不然就会报错.
三,重启sphinx,代码如下:
- # pkill searchd
- # /usr/local/sphinx/bin/indexer --config /usr/local/sphinx/etc/sphinx.conf --all
- # /usr/local/sphinx/bin/searchd --config /usr/local/sphinx/etc/sphinx.conf
四,测试sphinx,代码如下:
- [root@localhost etc]# mysql -h 127.0.0.1 -P 9306 //登录sphinx,9306端口,不是真实的mysql
- Welcome to the MySQL monitor. Commands end with ; or \g.
- Your MySQL connection id is 1
- Server version: 1.11-id64-dev (r2540)

- Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
- mysql> select * from myorder where match('张');
- +------+--------+------------+------------+-------------+----------------+
- | id | weight | user_id | username | create_time | product_name |
- +------+--------+------------+------------+-------------+----------------+
- | 9 | 1304 | 1311895262 | 张三 | 1406823894 | tank is 坦克 |
- | 10 | 1304 | 1311895263 | tank张二 | 1406823894 | tank is 坦克 |
- | 11 | 1304 | 1311895264 | tank张一 | 1406823894 | tank is 坦克 |
- | 12 | 1304 | 1311895265 | tank张 | 1406823894 | tank is 坦克 |
- +------+--------+------------+------------+-------------+----------------+
- 4 rows in set (0.01 sec)
- mysql> select * from myorder where match('张三');
- +------+--------+------------+----------+-------------+----------------+
- | id | weight | user_id | username | create_time | product_name |
- +------+--------+------------+----------+-------------+----------------+
- | 9 | 2500 | 1311895262 | 张三 | 1406823894 | tank is 坦克 |
- +------+--------+------------+----------+-------------+----------------+
- 1 row in set (0.00 sec)
