如图,字段tid保存的是文章标签id,用逗号分隔的字符串,我现在想通过标签,来查出来所有的文章,比如“2”,来查出所有tid字段里有2的文章,现在我用SELECT * FROM `t_ms_article` WHERE `tid` IN (2)语句只能查出来以2开头的文章,而不能查出来‘1,2,3’这样的
希望能帮我一下,我是菜鸟
回复讨论(解决方案)
SELECT * FROM `t_ms_article` WHERE `tid` LIKE ‘%2%’;
SELECT * FROM `t_ms_article` WHERE `tid` LIKE ‘%2%’;
不行的,这样的话会把12、20这样的标签也给查出来的
SELECT * FROM `t_ms_article` WHERE find_in_set('2', `tid`)
SELECT * FROM `t_ms_article` WHERE CONCAT(',',`tid`,',') LIKE ‘%,2,%’;
SELECT * FROM `t_ms_article` WHERE find_in_set('2', `tid`)
多谢,一下就解决了,大神请收下我的膝盖!

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
