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:

--==================================================================================================================--    ScriptName      :      get_login_rights_script.sql--    Author        :      潇湘隐者  --    CreateDate      :      2015-12-18--    Description      :      查看某个登录名被授予的数据库对象的权限的脚本(授权脚本和回收权限脚本)--    Note         :      /******************************************************************************************************************    Parameters       :                  参数说明********************************************************************************************************************      @login_name     :      你要查看权限的登录名(需要输入替换的参数)********************************************************************************************************************  Modified Date  Modified User   Version         Modified Reason********************************************************************************************************************  2018-08-03    潇湘隐者     V01.00.00    新建该脚本。  2019-04-04    潇湘隐者     V01.01.00    Fix掉一个bug,某个表只允许更新某个字段,但是这里显示更新整个表。  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。  2019-09-25    潇湘隐者     V01.03.00    解决数据库名包含中划线[-], 出现下面错误问题-------------------------------------------------------------------------------------------------------------------Msg 911, Level 16, State 1, Line 1Database 'xxxx' does not exist.
