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

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。
