Sql獲取SQL Server中特定數據庫的最新完整備份文件

Question

我需要一個sql命令（dbcc或擴展存儲過程？）或可以從sql server存儲過程調用的某個東西來獲取最新的完整備份文件可用於特定數據庫。備份文件的名稱將放置在varchar變量中，我可以在存儲過程中使用RESTORE DATABASE命令。此過程將用於從生產數據庫恢復到沙箱/培訓數據庫，因此在恢復完成後，我需要該過程繼續運行，以便對db進行一些修改。

只是「源」刺服務器上查詢msdb..backupset (MSDN)

而一個working example (SQL Rockstar)太

SELECT 
    bs.database_name, 
    bs.backup_start_date, 
    bmf.physical_device_name 
FROM 
    msdb.dbo.backupmediafamily bmf 
    JOIN 
    msdb.dbo.backupset bs ON bs.media_set_id = bmf.media_set_id 
WHERE 
    bs.database_name = 'MyDB' 
ORDER BY 
    bmf.media_set_id DESC;

我有，當我恢復最近，我的一個方便的腳本從目錄備份到要還原到的數據庫。使用夜間工作來刷新開發或測試盒非常棒！

declare @backupfile as Varchar(255) 

SELECT TOP 1 @backupfile=mf.physical_device_name from msdb..backupset bk  
join msdb..backupmediafamily mf on bk.media_set_id = mf.media_set_id 
where database_name=N'sourcedatabasename' and bk.type='D' order by 
backup_set_id desc 

ALTER DATABASE [databasename] SET SINGLE_USER WITH ROLLBACK IMMEDIATE 

RESTORE DATABASE databasename 
FROM DISK = @backupfile 
WITH MOVE 'datafile' TO 'databasefilepath', 
MOVE 'logfilename' TO 'logfilepath', REPLACE 

ALTER DATABASE [databasename] SET MULTI_USER WITH ROLLBACK IMMEDIATE

只是想給一個除從user2378139的出色答卷。我經常需要從1個文件夾中恢復多個數據庫，並且該文件夾中的每個數據庫都會有多個備份副本。我需要獲取最新的信息，並在計劃的任務上運行它。以下是我的編輯/更新來實現這一點。有更多的臨時表比我想要的，但還沒有想出一個更好的方式來做到這一點：

IF OBJECT_ID('tempdb..#TemperedFileList') IS NOT NULL DROP TABLE #TemperedFileList 
GO 
Declare @FileName varChar(255) 
Declare @cmdText varChar(255) 
Declare @BKFolder varchar(255) 
Declare @DBFolder varchar(255) 

set @FileName = null 
set @BKFolder = 'E:\SQLBackupFolder\' 
set @DBFolder = 'C:\Program Files\Microsoft SQL Server\MSSQL13.COBRASERVER\MSSQL\DATA\' 

declare @FileList table (FileName varchar(255), DepthFlag int, FileFlag int) 
--get all the files and folders in the backup folder and put them in temporary table 
insert into @FileList exec xp_dirtree @BKFolder,0,1 

create table #TemperedFileList (FileName varchar(255),DBName varchar(255)) 
insert into #TemperedFileList (FileName,DBName) select FileName, SUBSTRING(FileName,0,CHARINDEX('_',FileName)) from @FileList WHERE Filename like '%.bak' 

declare @RowCnt int 
declare @MaxRows int 
declare @tmpFileName varchar(255) 
declare @tmpDBName varchar(255) 
declare @sql nvarchar(3000) 

select @RowCnt = 1 

declare @Import table (rownum int IDENTITY (1, 1) Primary key NOT NULL , FileName varchar(255),DBName varchar(255)) 
insert into @Import (FileName,DBName) SELECT FileName,DBName FROM (SELECT FileName,DBName,rank() over (partition by DBName order by FileName desc) r FROM #TemperedFileList) ilv where r=1 

select @MaxRows=count(*) from @Import 
while @RowCnt <= @MaxRows 
begin 
    select @tmpFileName=FileName from @Import where rownum = @RowCnt 
    select @tmpDBName=DBName from @Import where rownum = @RowCnt 

    set @sql ='ALTER DATABASE ' + @tmpDBName + ' SET SINGLE_USER WITH ROLLBACK IMMEDIATE' 
    print @sql 
    exec(@sql) 

    set @sql ='RESTORE DATABASE [' + @tmpDBName + '] FROM DISK=''' + @BKFolder + @tmpFileName + ''' with FILE=1, MOVE N''' + @tmpDBName + ''' TO N''' + @DBFolder + @tmpDBName + '.mdf'', MOVE N''' + @tmpDBName + '_Log'' TO N''' + @DBFolder + @tmpDBName + '_log.ldf'', NOUNLOAD, REPLACE, STATS = 10' 
    print @sql 
    exec(@sql) 

    set @sql ='ALTER DATABASE ' + @tmpDBName + ' SET MULTI_USER WITH ROLLBACK IMMEDIATE' 
    print @sql 
    exec(@sql) 

    Set @RowCnt = @RowCnt + 1 
end
