SQL Server之9:sql查询与修改数据库逻辑文件名,移动数据库存储路径
引自http://blog.csdn.net/htl258/article/details/5696591,觉得挺有用
USE mydb GO --1.查询当前数据库的逻辑文件名 SELECT FILE_NAME(1) AS 'File Name 1', FILE_NAME(2) AS 'File Name 2'; --或通过以下语句查询: --SELECT name FROM sys.database_files /* File Name 1 File Name 2 ------------------- -------------------- mydb mydb_log (1 行受影响) */ --2.修改数据文件或日志文件的逻辑名称 ALTER DATABASE [mydb] MODIFY FILE ( NAME = mydb, NEWNAME = new_mydb ) ALTER DATABASE [mydb] MODIFY FILE ( NAME = mydb_log, NEWNAME = new_mydb_log ) --查询更改后的名称: SELECT FILE_NAME(1) AS 'File Name 1', FILE_NAME(2) AS 'File Name 2'; /* File Name 1 File Name 2 ------------------- -------------------- new_mydb new_mydb_log (1 行受影响) */ --3.若要将数据文件或日志文件移至新位置,先OFFLINE把文件MOVE到相应的位置,然后再ONLINE -- 详细参考以下步骤 --3.1 查询数据文件或日志文件当前存放路径: SELECT physical_name FROM sys.database_files /* physical_name ------------------------------------------------------------------------------------------- D:/Program Files/Microsoft SQL Server/MSSQL10.MSSQLSERVER/MSSQL/DATA/mydb.mdf D:/Program Files/Microsoft SQL Server/MSSQL10.MSSQLSERVER/MSSQL/DATA/mydb_log.ldf (2 行受影响) */ --3.2 移动路径 USE [master] GO --3.2.1 关闭所有进程 DECLARE @str VARCHAR(500); SET @str = ''; SELECT @str = @str + 'KILL '+RTRIM(spid)+';'+CHAR(13)+CHAR(10) FROM master.dbo.sysprocesses WHERE dbid=DB_ID('mydb'); EXEC(@str); GO --3.2.2 设置数据库脱机 ALTER DATABASE [mydb] SET OFFLINE GO --3.2.3 移动数据文件与日志文件(为确保数据安全,建议改move为copy,复制成功后再删除源文件) EXEC master..xp_cmdshell 'move "D:/Program Files/Microsoft SQL Server/MSSQL10.MSSQLSERVER/MSSQL/DATA/mydb.mdf" "E:/DBTEST"',NO_OUTPUT EXEC master..xp_cmdshell 'move "D:/Program Files/Microsoft SQL Server/MSSQL10.MSSQLSERVER/MSSQL/DATA/mydb_log.LDF" "E:/DBTEST"',NO_OUTPUT GO --3.2.4 设置新的存储路径 ALTER DATABASE [mydb] MODIFY FILE (NAME = new_mydb,FILENAME = 'E:/DBTEST/mydb.mdf') ALTER DATABASE [mydb] MODIFY FILE (NAME = new_mydb_log,FILENAME = 'E:/DBTEST/mydb_log.ldf') GO --3.2.5 设置数据库联机 ALTER DATABASE [mydb] SET ONLINE GO --3.2.6 查询新的路径 USE mydb GO SELECT physical_name FROM sys.database_files /* physical_name ------------------------------ E:/DBTEST/mydb.mdf E:/DBTEST/mydb_log.ldf (2 行受影响) */
