在SQL Server數(shù)據(jù)庫(kù)中如何查看一個(gè)登錄名(login)的具體權(quán)限呢，如果使用SSMS的UI界面查看登錄名的具體權(quán)限的話，用戶(hù)數(shù)據(jù)庫(kù)非常多的話，要梳理完它所有的權(quán)限，操作又耗時(shí)又麻煩，個(gè)人十分崇尚簡(jiǎn)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(kù))，都是不可接受的。最近遇到這個(gè)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(gè)登錄名所擁有的服務(wù)器角色、數(shù)據(jù)庫(kù)角色、以及所授予具體對(duì)象的相關(guān)權(quán)限使用腳本查詢(xún)出來(lái)，腳本分享如下：
