php SQL判断字符串的方法求解
- SQL code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->$dsql->SetQuery("SELECT a.id,a.title,a.flag,b.aid,b.imgurl FROM `#@__archives` a Join `#@__addonarticle` b On a.id = b.aid where a.flag = 'f' ORDER BY a.id DESC LIMIT 0,4");
以上 a.flag为字符串 在数据库中为 c,f,p,h,a
以上SQL查询flag为f没问题 请问怎么查询c,f或者c,f,p？ 另外c,f,p能不能打乱了写？
------解决方案--------------------
............a.flag like '%c,f%'
------解决方案--------------------
SQL判断字符串 .a.flag like '%c,f%'
------解决方案--------------------
str.a.flag like '%c,f%'就这样啊。很简单的

如何使用exp进行SQL报错注入May 12, 2023 am 10:16 AM0x01前言概述小编又在MySQL中发现了一个Double型数据溢出。当我们拿到MySQL里的函数时，小编比较感兴趣的是其中的数学函数，它们也应该包含一些数据类型来保存数值。所以小编就跑去测试看哪些函数会出现溢出错误。然后小编发现，当传递一个大于709的值时，函数exp()就会引起一个溢出错误。mysql>selectexp(709);+-----------------------+|exp(709)|+-----------------------+|8.218407461554972
如何在Python中根据运行时修改业务SQL代码？May 08, 2023 pm 02:22 PM1.缘起最近项目在准备搞SASS化，SASS化有一个特点就是多租户，且每个租户之间的数据都要隔离，对于数据库的隔离方案常见的有数据库隔离，表隔离，字段隔离，目前我只用到表隔离和字段隔离（数据库隔离的原理也是差不多）。对于字段隔离比较简单，就是查询条件不同而已，比如像下面的SQL查询：SELECT*FROMt_demoWHEREtenant_id='xxx'ANDis_del=0但是为了严谨，需求上需要在执行SQL之前检查对应的表是否带上tenant_id的查询字段
