      • sql語句大全之SQL server權限管理和備份實例

      • 2019-04-29 21:35 來源:未知

      權限設置:

      1、創建用戶zhangsan,并賦予zhangsan有dbcreator的服務器權限。

      2、使用zhangsan登錄,測試能否創建數據庫。

      3、使用sa用戶附加myschool數據庫,設置zhangsan能執行select語句查詢數據庫中的表數據。并設置zhangsan用戶能刪除student表中的數據。

      4、使用zhangsan登錄測試權限。

       

      備份與還原:

      1、驗證時間點還原(完整備份+事務日志備份)

      思路:創建一個數據庫benet,再創建一個表stu。先做一次完整備份,然后向文件中寫入數據,隔一分鐘寫一行,然后做事物日志備份,還原到某一時間點。

      2、尾部備份

      思路:建立數據庫accp,再創建一個stu表。先做一次完整備份,然后向文件中寫入數據,但是不備份,然后把sqlserver服務停止,停止之后刪除accp.mdf主數據庫文件,把服務開啟,進行尾部備份,然后還原(之前沒有備份的數據也還原回來)。

      3、創建數據庫維護計劃每周日晚上22:00對bdqn數據庫進行完整備份;每天12:00和18:00對該數據庫進行事務日志備份。修改系統時間,驗證備份效果。
