更改數(shù)據(jù)庫名

(1)

alter database database_name

modify name=new_database_name

(2)

sp_renamedb olddbname,newdbname

添加數(shù)據(jù)文件和文件組(擴(kuò)大)

(1)添加數(shù)據(jù)文件

USE master

GO

DECLARE @data_path nvarchar(256);

-- 獲取主數(shù)據(jù)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(shù)據(jù)文件(放在主數(shù)據(jù)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(shù)據(jù)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(shù)據(jù)文件(放在主數(shù)據(jù)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(chuàng)建文件組_1

ALTER DATABASE MyDatabase

ADD FILEGROUP UserFG1_1;

GO

DECLARE @data_path nvarchar(256);

--獲取主數(shù)據(jù)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(shù)據(jù)文件(放在主數(shù)據(jù)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(shù)據(jù)文件時(shí)如果不指定所在文件組那么將被默認(rèn)添加到主文件組中

更改數(shù)據(jù)文件和文件組

(1)更改數(shù)據(jù)庫的數(shù)據(jù)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(shù)據(jù)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(shè)置初始大小

MAXSIZE = 50MB, -- 設(shè)置文件的最大存儲(chǔ)空間

FILEGROWTH = 5MB -- 設(shè)置自動(dòng)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(rèn)文件組

USE master;

GO

ALTER DATABASE MyDatabase6

MODIFY FILEGROUP newUserFG6_2 DEFAULT;

GO

ALTER DATABASE MyDatabase6

MODIFY FILEGROUP [PRIMARY] DEFAULT;

GO
