数据库文件与文件组

1、创建数据库
CREATE DATABASE [tt] ON  PRIMARY 
( NAME = N'tt', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10.YUBO2114653\MSSQL\DATA\tt.mdf' , SIZE = 3072KB , FILEGROWTH = 1024KB )
 LOG ON 
( NAME = N'tt_log', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10.YUBO2114653\MSSQL\DATA\tt_log.ldf' , SIZE = 1024KB , FILEGROWTH = 10%)

2、创建数据库并创建名字为Testdat1的文件

CREATE DATABASE Test1 ON
(
 NAME = Test1dat1, 
 FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL10.YUBO2114653\MSSQL\DATA\t1dat1.ndf',
 SIZE = 5MB,
 MAXSIZE = 100MB,
 FILEGROWTH = 5MB
)

3、数据库Test1中新增文件
ALTER DATABASE Test1 
ADD FILE 
(
 NAME = Test1dat2,
 FILENAME = 'c:\Program Files\Microsoft SQL Server\MSSQL\Data\t1dat2.ndf',
 SIZE = 5MB,
 MAXSIZE = 100MB,
 FILEGROWTH = 5MB
)

4、在数据库Test1中新增文件组Test1FG1；并在此文件组中增加两个文件；将此文件组设置为默认文件组

ALTER DATABASE Test1
ADD FILEGROUP Test1FG1
GO
ALTER DATABASE Test1 
ADD FILE 
( NAME = test1dat3,
  FILENAME = 'c:\Program Files\Microsoft SQL Server\MSSQL\Data\t1dat3.ndf',
  SIZE = 5MB,
  MAXSIZE = 100MB,
  FILEGROWTH = 5MB),
( NAME = test1dat4,
  FILENAME = 'c:\Program Files\Microsoft SQL Server\MSSQL\Data\t1dat4.ndf',
  SIZE = 5MB,
  MAXSIZE = 100MB,
  FILEGROWTH = 5MB)
TO FILEGROUP Test1FG1

ALTER DATABASE Test1
MODIFY FILEGROUP Test1FG1 DEFAULT
GO
