sphinx也就是一個像mysql數據庫的工具了,我們可以在linux中使用sphinx來替換mysql了,下面小編整理了幾個sphinx聯合查詢的語句,記得以前sphinx是不支持聯合查詢的,第一次接觸sphinx,好像2010年初的時候,當時寫過一篇關于sphinx安裝的文章,sphinx mmseg mysql 中文分詞,下面舉例說明,sphinx的聯合查詢用法.
一,添加二張測試表和數據,代碼如下:
1,users表和數據
- 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)
- --Vevb.com
- mysql> select * from users;
- +------------+------------+
- | user_id | username |
- +------------+------------+
- | 1311895262 | 張三 |
- | 1311895263 | tank張二 |
- | 1311895264 | tank張一 |
- | 1311895265 | tank張 |
- +------------+------------+
- 4 rows in set (0.00 sec)
2,orders表和數據
- 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 | 技術總監 |
- | 10 | 1311895263 | 2014-08-01 00:24:54 | tank is 坦克 | 技術經理 |
- | 11 | 1311895264 | 2014-08-01 00:24:54 | tank is 坦克 | DNB經理 |
- | 12 | 1311895265 | 2014-08-01 00:24:54 | tank is 坦克 | 運維總監 |
- +----+------------+---------------------+----------------+--------------+
- 4 rows in set (0.00 sec)
二,配置sphinx.conf,代碼如下:
- 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:在這里a.user_id = b.user_id,等號二邊一定要有空格,不然就會報錯.
三,重啟sphinx,代碼如下:
- # 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,測試sphinx,代碼如下:
- [root@localhost etc]# mysql -h 127.0.0.1 -P 9306 //登錄sphinx,9306端口,不是真實的mysql
- Welcome to the MySQL monitor. Commands end with ; or \g.
- Your MySQL connection id is 1

- mysql> select * from myorder where match('張');
- +------+--------+------------+------------+-------------+----------------+
- | id | weight | user_id | username | create_time | product_name |
- +------+--------+------------+------------+-------------+----------------+
- | 9 | 1304 | 1311895262 | 張三 | 1406823894 | tank is 坦克 |
- | 10 | 1304 | 1311895263 | tank張二 | 1406823894 | tank is 坦克 |
- | 11 | 1304 | 1311895264 | tank張一 | 1406823894 | tank is 坦克 |
- | 12 | 1304 | 1311895265 | tank張 | 1406823894 | tank is 坦克 |
- +------+--------+------------+------------+-------------+----------------+
- 4 rows in set (0.01 sec)
- mysql> select * from myorder where match('張三');
- +------+--------+------------+----------+-------------+----------------+
- | id | weight | user_id | username | create_time | product_name |
- +------+--------+------------+----------+-------------+----------------+
- | 9 | 2500 | 1311895262 | 張三 | 1406823894 | tank is 坦克 |
- +------+--------+------------+----------+-------------+----------------+
- 1 row in set (0.00 sec)
