Question

我在创建备份时进行了描述。

我可以检索有关我的备份的信息：

SELECT name, database_name, description, backup_start_date FROM msdb.dbo.backupset

我可以使用说明和/或备份创建日期按脚本还原数据库吗？

我需要类似的东西：

RESTORE DATABASE [MyDB] FROM  DISK = N'D:\dbbackups\ByDB.bak'
Where Description = 'SomeDescr' and Date = '10.05.2016'

Answer 1

我找到了一种方法

declare @Position int = 0;

SELECT @Position = position
FROM msdb.dbo.backupset
where database_name = 'MyDB'
and type = 'I' and Description = 'some description'

print @Position

ALTER DATABASE [myDB] SET  SINGLE_USER WITH ROLLBACK IMMEDIATE


RESTORE DATABASE [myDB] FROM  DISK = N'D:\dbbackups\myDB.bak' WITH  FILE = 1,  NORECOVERY,  NOUNLOAD,  REPLACE,  STATS = 5
RESTORE DATABASE [myDB] FROM  DISK = N'D:\dbbackups\myDB.bak' WITH  FILE = @Position,  NOUNLOAD,  STATS = 5

如何通过备份描述恢复SQL Server数据库？
