當(dāng)恢復(fù)sqlserver bak文件時(shí)，原始的用戶無法刪除的解決方法

當(dāng)你從現(xiàn)有的bak文件，恢復(fù)數(shù)據(jù)庫時(shí)，如果數(shù)據(jù)庫本身帶有一個用戶：比如用戶叫：DemoUser.

你無法創(chuàng)建一個相同的用戶并mapping這個用戶到數(shù)據(jù)庫， 并且你無法刪除數(shù)據(jù)庫的用戶：DemoUser.
請運(yùn)行以下腳本， 之后你就可以刪除用戶：DemoUser.然后創(chuàng)建用戶（DemoUser.）并mapping到數(shù)據(jù)庫。
