是否可以使用联接对具有两个表的查询进行匹配?棘手的部分可能是表上的索引，但也许有一种方法.sql不是我的强项.非常感谢.我想可能是这样的:

Is it possible to do a match against a query with two tables using a join? The tricky part might be the index on the table but maybe there is a way.. sql is not my strong suit. Many thanks. I imagine it might be something like the following:

SELECT * FROM 'pages' p LEFT JOIN `tags` t ON p.id = u.pageid WHERE MATCH(p.shdescript,t.tag) AGAINST ('romance, relationship')

非常感谢

推荐答案

可能，但是您需要文本索引.

It's possible, but you need to have text indexes.

mysql> alter table pages add fulltext index_text(shdescript); mysql> alter table tags add fulltext index_text(tag); SELECT * FROM 'pages' p LEFT JOIN `tags` t ON p.id = u.pageid WHERE MATCH(p.shdescript,t.tag) AGAINST ('romance relationship')

我想这足以工作.

从MySQL 5.6开始，上述全文搜索可以在MyISAM& InnoDB存储引擎.在早期的MySQL版本上，只有MyISAM表支持全文索引.

As of MySQL 5.6 the above fulltext search can be done on the MyISAM & InnoDB storage engines. On earlier MySQL versions only MyISAM tables supported fulltext indexes.
