在SQL Server數(shù)據(jù)庫中如何查看一個登錄名(login)的具體權限呢，如果使用SSMS的UI界面查看登錄名的具體權限的話，用戶數(shù)據(jù)庫非常多的話，要梳理完它所有的權限，操作又耗時又麻煩，個人十分崇尚簡潔、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，哪怕就是腳本，如果不能一次搞定，手工多操作幾次(例如，切換數(shù)據(jù)庫)，都是不可接受的。最近遇到這個需求，就完善了一下之前的腳本get_login_rights_script.sql，輸入登錄名參數(shù)，將這個登錄名所擁有的服務器角色、數(shù)據(jù)庫角色、以及所授予具體對象的相關權限使用腳本查詢出來，腳本分享如下：

  2019-04-04    瀟湘隱者     V01.01.00    Fix掉一個bug，某個表只允許更新某個字段，但是這里顯示更新整個表。
  2019-09-25    瀟湘隱者     V01.02.00    解決只能查看某個用戶數(shù)據(jù)庫，不能查看所有數(shù)據(jù)庫的權限問題。
  2019-09-25    瀟湘隱者     V01.03.00    解決數(shù)據(jù)庫名包含中劃線[-], 出現(xiàn)下面錯誤問題
