全局唯一标识符(GUID,Globally Unique Identifier)是一种由算法生成的二进制长度为128位的数字标识符。GUID主要用于在拥有多个节点、多台计算机的网络或系统中。在理想情况下,任何计算机和计算机集群都不会生成两个相同的GUIDGUID 的总数达到了2^128(3.4×10^38)个,所以随机生成两个相同GUID的可能性非常小,但并不为0。GUID一词有时也专指微软对UUID标准的实现。 在理想情况下,任何计算机和计算机集群都不会生成两个相同的GUID。随机生成两个相同GUID的可能性是非常小的,但并不为0。所以,用于生成GUID的算法通常都加入了非随机的参数(如时间),以保证这种重复的情况不会发生。 在 Windows 平台上,GUID 广泛应用于微软的产品中,用于标识如注册表项、类及接口标识、数据库、系统目录等对象。

主键的生成方式主要有三种: 一. 数据库自动生成 二. GUID 三. 开发创建 严格讲这三种产生方式有一定的交叉点,其定位方式将在下面进行讲解。 第一种方式,主要将其定位在自增长的标识种子:可以设置起始数值,及增长步长。其优点在于使用时完全将并发任务交于数据库引擎管理,你不用担心存在多用户使用的时候会产生两个相同的ID的情况。其缺点也在于此,多数的数据库不提供直接获取标识ID的方式,对于开发人员来说产生ID的方式是透明的,开发人员几乎无法干预此项。对于数据的迁移也不是很方便。 由于存在上面的利弊,这种自增长的ID一般多用于设计基础表(系统运行的基础信息,如员工表)主键,而极少(根本不)用于主
