我需要使用数据库备份数据库名称

Question

我需要每天进行数据库备份并将日期添加到数据库名称 - 例如：Navigate_2017-10-20.bak。

如何在数据库名称和日期中使用动态查询？

DECLARE @Date DATE = GETDATE() 

SELECT @Date 

BACKUP DATABASE [Navigate] 
TO DISK = N'D:\Working\Navigate_'+ @Date +'.bak' 
WITH NOFORMAT, NOINIT, 
NAME = N'Navigate-Full Database Backup', 
SKIP, NOREWIND, NOUNLOAD, COMPRESSION, STATS = 10 
GO 

Answer 1

转换日期为字符串，并创建事前的文件名：

DECLARE @Filename NVARCHAR(MAX); 

SELECT @FILENAME = N'D:\Working\Navigate_'+ CONVERT(char(10), GetDate(),126) +'.bak'; 


BACKUP DATABASE [Navigate] 
TO DISK = @FILENAME WITH NOFORMAT, NOINIT, 
NAME = N'Navigate-Full Database Backup', SKIP, NOREWIND, NOUNLOAD, COMPRESSION, STATS = 10; 
GO 

Answer 2

DECLARE @Date DATE = GETDATE() 

SELECT @Date 

BACKUP DATABASE [Navigate] 
TO DISK = N'D:\Working\Navigate_'+ CONVERT(NVARCHAR(20),@Date,105) +'.bak' WITH NOFORMAT, NOINIT, 
NAME = N'Navigate-Full Database Backup', SKIP, NOREWIND, NOUNLOAD, COMPRESSION, STATS = 10 
GO 

Answer 3

使用本

DECLARE @Date NVARCHAR(20) = CONVERT(NVARCHAR(20),GETDATE(),105) 
SELECT @Date 
BACKUP DATABASE [Navigate] 
TO DISK = N'D:\Working\Navigate_'+ @Date +'.bak' WITH NOFORMAT, NOINIT, 
NAME = N'Navigate-Full Database Backup', SKIP, NOREWIND, NOUNLOAD, COMPRESSION, STATS = 10
