更改數據庫名

(1)

alter database database_name

modify name=new_database_name

(2)

sp_renamedb olddbname,newdbname

添加數據文件和文件組(擴大)

(1)添加數據文件

USE master

GO

DECLARE @data_path nvarchar(256);

-- 獲取主數據文件的存放位置

SELECT @data_path=physical_name

FROM MyDatabase.sys.database_files

WHERE file_id=1;

SET @data_path=SUBSTRING(@data_path, 1, CHARINDEX(LOWER('MyDatabase.mdf')， LOWER(@data_path)) - 1);

-- 添加數據文件(放在主數據文件所在的目錄下)

go

ALTER DATABASE MyDatabase

ADD FILE

(

NAME = LogicNameOfDataFile1_1,

FILENAME = 'D:/Program Files/Microsoft SQL Server/MSSQL.1/MSSQL/DATA/DataFile1_1.ndf',

SIZE = 5MB,

MAXSIZE = 100MB,

FILEGROWTH = 5MB

)

(2)添加日志文件

USE master

GO

DECLARE @data_path nvarchar(256);

--獲取主數據文件的存放位置

SELECT @data_path=physical_name

FROM MyDatabase.sys.database_files

WHERE file_id=1;

SET @data_path=SUBSTRING(@data_path, 1, CHARINDEX(LOWER('MyDatabase.mdf')， LOWER(@data_path)) - 1);

--添加數據文件(放在主數據文件所在的目錄下)

go

ALTER DATABASE MyDatabase

ADD LOG FILE

(

NAME = LogicNameOfLogFile1_1,

FILENAME = 'D:/Program Files/Microsoft SQL Server/MSSQL.1/MSSQL/DATA/LogFile1_1.ldf',

SIZE = 2MB,

MAXSIZE = 50MB,

FILEGROWTH = 3MB

)

(3)添加文件及文件組

USE master

GO

-- 創建文件組_1

ALTER DATABASE MyDatabase

ADD FILEGROUP UserFG1_1;

GO

DECLARE @data_path nvarchar(256);

--獲取主數據文件的存放位置

SELECT @data_path=physical_name

FROM MyDatabase.sys.database_files

WHERE file_id=1;

SET @data_path=SUBSTRING(@data_path, 1, CHARINDEX(LOWER('MyDatabase.mdf')， LOWER(@data_path)) - 1);

--添加數據文件(放在主數據文件所在的目錄下)

Go

ALTER DATABASE MyDatabase

ADD FILE

(

NAME = LogicNameOfDataFile1_2,

FILENAME = 'D:/Program Files/Microsoft SQL Server/MSSQL.1/MSSQL/DATA/DataFile1_2.ndf',

SIZE = 10MB,

MAXSIZE = 50MB,

FILEGROWTH = 5MB

)，

(

NAME = LogicNameOfDataFile1_3,

FILENAME = 'D:/Program Files/Microsoft SQL Server/MSSQL.1/MSSQL/DATA/DataFile1_3.ndf',

SIZE = 5MB,

MAXSIZE = 50MB,

FILEGROWTH = 2MB

)

TO FILEGROUP UserFG1_1

注：以上添加數據文件時如果不指定所在文件組那么將被默認添加到主文件組中

更改數據文件和文件組

(1)更改數據庫的數據文件

USE master

GO

ALTER DATABASE MyDatabase2

MODIFY FILE

(

NAME = LogicNameOfDataFile2,

NEWNAME = newLogicNameOfDataFile2,

FILENAME

='C:/Program Files/Microsoft SQL Server/MSSQL10.MSSQLSERVER/MSSQL/DATA/newDataFile2.mdf',

SIZE = 25MB,

MAXSIZE = 150MB,

FILEGROWTH = 10MB

)

(2)更改數據庫的日志文件

USE master

GO

ALTER DATABASE MyDatabase3

MODIFY FILE

(

NAME = MyDatabase3_log,

FILENAME

='C:/Program Files/Microsoft SQL Server/MSSQL10.MSSQLSERVER/MSSQL/DATA/LogFile3.LDF',

SIZE = 10MB , -- 設置初始大小

MAXSIZE = 50MB, -- 設置文件的最大存儲空間

FILEGROWTH = 5MB -- 設置自動增長幅度

)

(3)更改文件組名稱

USE master

GO

ALTER DATABASE MyDatabase6

MODIFY FILEGROUP UserFG6_2 NAME = newUserFG6_2

GO

(4)更改默認文件組

USE master;

GO

ALTER DATABASE MyDatabase6

MODIFY FILEGROUP newUserFG6_2 DEFAULT;

GO

ALTER DATABASE MyDatabase6

MODIFY FILEGROUP [PRIMARY] DEFAULT;

GO
