高手指点下,mysql语句的疑问?提供具体的思路?
数据库里面存在一字段 如strvalue(varchar) 其保存的值类似:1,2,5,7 或1,2,8,9 这样
1、现在从网页上获取到值 为1 或9不定,
写个select 语句查询出 数据库中满足1,或5 的行。。。
好像用like 不行,用一句可以实现吗?
2、要是从网页上(复选框得到的)获取到值 为1,2或8,9不定,
写个select 语句查询出 数据库中满足1,2,或8,9 的行。。。
------解决方案--------------------
where strvalue link '%1%' or strvalue link '%5%'
------解决方案--------------------
做成全文索引
------解决方案--------------------
- SQL code
where strvalue like '1,2%' or strvalue like '%8,9' <div class="clear"> </div>

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
