以下是自己编写自动生成文件名备份数据库：

DECLARE @filename VARCHAR(255)
DECLARE @date DATETIME
SELECT @date=GETDATE()
SELECT @filename = ‘D:\BackUp\SQL-‘+CAST(DATEPART(yyyy,@date) as varchar)
+‘-‘+CAST(DATEPART(mm,@date) as varchar)+‘-‘+CAST(DATEPART(dd,@date) as varchar)+‘.bak‘
BACKUP DATABASE [backupname] TO  DISK = @filename WITH INIT
GO

以下是删除数据库：

DECLARE @filename VARCHAR(255)
DECLARE @date DATETIME
SELECT @date=GETDATE()
SELECT @filename = ‘‘D:\BackUp\SQL-‘‘+CAST(DATEPART(yyyy,@date) as varchar)
+‘‘-‘‘+CAST(DATEPART(mm,@date) as varchar)+‘‘-‘‘+CAST(DATEPART(dd,@date) as varchar)+‘‘.bak‘‘
BACKUP DATABASE 【backupname】TO  DISK = @filename WITH INIT
GO
