Question

我有两个表正在加入（为了获取用户名，我在user_id上加入它们）。

以下是我的帐户表格结构：

+-----------+------------------+------+-----+-------------------+----------------+
| Field     | Type             | Null | Key | Default           | Extra          |
+-----------+------------------+------+-----+-------------------+----------------+
| user_id   | int(10) unsigned | NO   | PRI | NULL              | auto_increment |
| username  | varchar(20)      | NO   |     | NULL              |                |
| email     | varchar(128)     | YES  |     | NULL              |                |
| timestamp | timestamp        | YES  |     | CURRENT_TIMESTAMP |                |
| hashed_pw | varchar(255)     | YES  |     | NULL              |                |
| active    | char(32)         | YES  |     | NULL              |                |
+-----------+------------------+------+-----+-------------------+----------------+

以下是我的提交表格结构

+-------------+------------------+------+-----+-------------------+----------------+
| Field       | Type             | Null | Key | Default           | Extra          |
+-------------+------------------+------+-----+-------------------+----------------+
| id          | int(10) unsigned | NO   | PRI | NULL              | auto_increment |
| title       | varchar(255)     | NO   | MUL | NULL              |                |
| description | varchar(255)     | YES  |     | NULL              |                |
| source      | varchar(255)     | NO   |     | NULL              |                |
| category    | varchar(64)      | NO   |     | NULL              |                |
| user_id     | int(10) unsigned | NO   | MUL | NULL              |                |
| submit_ip   | int(4) unsigned  | NO   |     | NULL              |                |
| timestamp   | timestamp        | NO   | MUL | CURRENT_TIMESTAMP |                |
| thumbnail   | varchar(255)     | YES  |     | NULL              |                |
+-------------+------------------+------+-----+-------------------+----------------+

现在，我正在使用以下查询来获取我需要的内容，并且它运行正常：

SELECT Submissions.title, Submissions.description, Submissions.timestamp,
Accounts.user_id 

FROM `Submissions` 

INNER JOIN `Accounts` ON 

Submissions.user_id=Accounts.user_id;

这给了我以下结果：

*************************** 1. row ***************************
  title: IJL that one of the men who discovered the stratosphere had a very unfortunate 
name.
description: 
  timestamp: 2011-04-27 01:43:54
    user_id: 8
*************************** 2. row ***************************
      title: IJL that nuclear reactors actually glow blue.
description: Testing the description out on this one
  timestamp: 2011-04-27 02:05:12
    user_id: 8

我想在Submissions.title和Submissions.description上对结果集执行全文搜索，如：

WHERE MATCH (Submissions.title, Submissions.description) AGAINST (?)

如何将此添加到我当前的查询中以获得所需的结果？

Answer 1

首先这样做

ALTER TABLE Submissions ADD FULLTEXT(title, description);

这将为这两列添加全文搜索

这样做

WHERE MATCH (title, description) AGAINST (’keyword’);

如何在MySQL的INNER JOIN中进行全文搜索？
