最近遇到這樣一個案例,需要修改所有SQL Server的Database Mail的SMTP,原來的SMTP為10.xxx.xxx.xxx, 現在需要修改為192.168.xxx.xxx, 另外需要規范郵件地址,以前這類郵件ServerName@yoursqldba.com的后綴需要修改為ServerName@xxxx.com(信息做了脫敏處理)。
如果使用SSMS客戶端的UI界面去修改的話, 那么多服務器一臺一臺去修改,不僅費時費力,而且枯燥無聊。只能使用腳本,一旦寫好一個腳本,而后使用Multiple Server Query Execution(極力推薦使用這個管理、維護數據庫),執行一次腳本,全部搞定。剩下的時間你可以喝喝茶、學習下新知識!
