当使用第三方登录时会生成一个 CSDN ID：u012365644
请教该ID是如何生成的？ 绝对唯一吗？
回复讨论(解决方案)
可以考虑数据库中的id自动增长。
理论上绝对唯一，生成的方法应该是自增（这种编号的规则一般都是自己定义的）

哦，其实我也这样想过！
用户表有一字段account，该字段唯一！
当第三方账号登录时，会注册生成一随机账号substr('U'.$uid.uniqid(rand()),0,10)，但其中的这个$uid如何获取呢？

第三方登录，第一次的时候，会在本地有保存信息的吧，这个时候要加入一个用户记录项

我是这样的：
1、一个user表、一个user_platform第三方账号绑定表
2、user_platform表中有id（自增）、uid（对应user表中的用户uid）、type（第三方标志如qq）、openid（第三方返回唯一id）
3、当第三方账号第一次登录时，首先会在user表中创建一账号，账号创建成功后，才会在user_platform表中，写入绑定记录，即记录新创建的用户uid和openid
同于先后顺序，所以在创建新用户账号时，我需要先得到uid！这是我的思路，请问你是怎么做的呢，第一次弄第三方登录？
我第一次弄这个，不知道思路正不正确
我表示好烂的ID 还不能改

mysql有自动增长的字段，保证唯一性
应该是自动增长函数 而不是标识列
mysql有自动增长的字段，保证唯一性
但是在插入数据时，如何先知道自增uid呢

插入数据成功，返回当前自增的id即可。

数据插入成功，就不需要id了！ 在插入一条记录的同时，如何保证生成的account字段唯一（其中uid自增）？
因为uid自增，所以想通过uid+字符串确保生成的账号唯一。
如果不能这样得到自增uid，就只有再写一条更新语句！
不会的自增的，因为CSDN肯定做了用户的分库，这样，多个库中都会有类似uid相同的，他的uid应该是随机出来的，只是这个随机的比较复杂而已
