SQL Server查看login所授予的具体权限问题

在SQL Server数据库中如何查看一个登录名(login)的具体权限呢，如果使用SSMS的UI界面查看登录名的具体权限的话，用户数据库非常多的话，要梳理完它所有的权限，操作又耗时又麻烦，个人十分崇尚简洁、高效的方法，反感那些需要大量手工操作的UI界面操作方式，哪怕就是脚本，如果不能一次搞定，手工多操作几次(例如，切换数据库)，都是不可接受的。最近遇到这个需求，就完善了一下之前的脚本get_login_rights_script.sql，输入登录名参数，将这个登录名所拥有的服务器角色、数据库角色、以及所授予具体对象的相关权限使用脚本查询出来，脚本分享如下：

  2019-09-25    潇湘隐者     V01.02.00    解决只能查看某个用户数据库，不能查看所有数据库的权限问题。
