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:
