E+14 超大整数的mysql存储问题
最近做淘宝api的开发，遇到淘宝的订单号；是一个15位的整数，从淘宝数据库取得的是用科学计数法表示的：3.09086009604219E+14，以前遇到11位以上的数字，都是做成varchar；但是后面用到淘宝api又必须明确使用整型订单号，请问一下这样一个超大的整数是怎么存储到mysql的啊，用float吗？？？？？？
跪求跪求啊。。。。。。。

------解决方案--------------------
bigint
------解决方案--------------------
肯定是不行的了，科学计数法已丢失了精度
只能以字符串保存

我不知道你是如何读的，至少库中是不可能保存成科学计数法的

------解决方案--------------------
那只是你读取之后输出显示是这个样子，设计好你的数据库字段类型插入即可。

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.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.
