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 1,users表和数据 mysql desc users;+------
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
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) 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
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
# 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
