代码如下:
DECLARE @filename VARCHAR(255)
DECLARE @date DATETIME
SELECT @date=GETDATE()
SELECT @filename = 'G:存放位置数据库名称-'+CAST(DATEPART(yyyy,@date) as varchar)+'-'+CAST(DATEPART(mm,@date) as varchar)+'-'+CAST(DATEPART(dd,@date) as varchar)+'.bak'
BACKUP DATABASE [数据库名称] TO DISK = @filename WITH INIT
GO
DECLARE @OLDDATE DATETIME
SELECT @OLDDATE=GETDATE()-5
EXECUTE master.dbo.xp_delete_file 0,N'G:存放位置',N'bak',@olddate,1
