SQL Server 中如何移动tempdb到新的位置

操作步骤；
１、检查tempdb的逻辑名字和它的存在位置。可以使用下面语句：

SELECT name, physical_name
FROM sys.master_files
WHERE database_id = DB_ID('tempdb');

 

 

２、停止数据库服务．

３、拷贝原来tempdb的文件到新的位置（原来文件位置可以通过上述查询得到）。拷贝完毕后，启动数据库服务。

４、执行如下命令：

USE master;
GO
ALTER DATABASE tempdb 
MODIFY FILE (NAME = tempdev, FILENAME = 'F:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\TempDB\tempdb.mdf');

ALTER DATABASE tempdb 
MODIFY FILE (NAME = temp2, FILENAME = 'F:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\TempDB\tempdb_mssql_2.ndf');

ALTER DATABASE tempdb 
MODIFY FILE (NAME = temp3, FILENAME = 'F:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\TempDB\tempdb_mssql_3.ndf');

ALTER DATABASE tempdb 
MODIFY FILE (NAME = temp4, FILENAME = 'F:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\TempDB\tempdb_mssql_4.ndf');

ALTER DATABASE tempdb 
MODIFY FILE (NAME = temp5, FILENAME = 'F:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\TempDB\tempdb_mssql_5.ndf');

ALTER DATABASE tempdb 
MODIFY FILE (NAME = temp6, FILENAME = 'F:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\TempDB\tempdb_mssql_6.ndf');

ALTER DATABASE tempdb 
MODIFY FILE (NAME = temp7, FILENAME = 'F:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\TempDB\tempdb_mssql_7.ndf');

ALTER DATABASE tempdb 
MODIFY FILE (NAME = temp8, FILENAME = 'F:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\TempDB\tempdb_mssql_8.ndf');

GO
ALTER DATABASE  tempdb 
MODIFY FILE (NAME = templog, FILENAME = 'F:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\TempDB\templog.ldf');
GO

在这里，name=tempdev 和templog 等是tempdb的逻辑名字，FILENAME = 'F:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\TempDB\tempdb.mdf' 是tempdb的新位置．

执行结果如下：

 

５、然后检查tempdb移动是否成功。

SELECT name, physical_name
FROM sys.master_files
WHERE database_id = DB_ID('tempdb');

 

 

6、接着重启数据库服务

 

7、注意在步骤3中，我们重新启动数据库服务的时候，还是会在老的tempdb路径下生成一套tempdb的数据库文件，现在它们都是没用的垃圾文件了，我们要去删掉它们。
