SQLServer2016--添加登录账号、后续练习脚本

登录验证方式介绍

SQLServer身份验证：适合于非Windows平台的用户或Interner用户，需要提供账户和密码。
Windows身份验证：适合与windows平台用户,不需要提供密码,和Windows集成验证。

创建多个Windows登录账号的方法

在本机计算创建多个Windows账号

例如-要使用Shark的Windows账号登录数据库：

use  mastergoexec sp_grantlogin 'SHARK2\Shark'

注销Windows后–启用新建的Shark用户就可以登录了

此创建方法局限于本机！！
建议用重点方法SQLServer创建登录用户

SQLServer创建登录用户

重点的SQLServer用户创建方法:

use  mastergoexec sp_addlogin 'SqlShark','aaa999a9'--登录名，密码
