SQL server資料庫創建代碼，filegroup文件組修改，

以下示例在 SQL Server 實例上創建了一個資料庫。該資料庫包括一個主數據文件、一個用戶定義文件組和一個日誌文件。主數據文件在主文件組中，而用戶定義文件組包含兩個次要數據文件。ALTER DATABASE 語句將用戶定義文件組指定為預設文件組。然後通過指定用戶定義文件組來創建表。

USE master;
GO
-- Create the database with the default data
-- filegroup and a log file. Specify the
-- growth increment and the max size for the
-- primary data file.
CREATE DATABASE MyDB
ON PRIMARY
( NAME='MyDB_Primary',
FILENAME=
'c:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\data\MyDB_Prm.mdf',
SIZE=4MB,
MAXSIZE=10MB,
FILEGROWTH=1MB),
FILEGROUP MyDB_FG1
( NAME = 'MyDB_FG1_Dat1',
FILENAME =
'c:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\data\MyDB_FG1_1.ndf',
SIZE = 1MB,
MAXSIZE=10MB,
FILEGROWTH=1MB),
( NAME = 'MyDB_FG1_Dat2',
FILENAME =
'c:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\data\MyDB_FG1_2.ndf',
SIZE = 1MB,
MAXSIZE=10MB,
FILEGROWTH=1MB)
LOG ON
( NAME='MyDB_log',
FILENAME =
'c:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\data\MyDB.ldf',
SIZE=1MB,
MAXSIZE=10MB,
FILEGROWTH=1MB);
GO
ALTER DATABASE MyDB 
MODIFY FILEGROUP MyDB_FG1 DEFAULT;
GO

-- Create a table in the user-defined filegroup.
USE MyDB;
CREATE TABLE MyTable
( cola int PRIMARY KEY,
colb char(8) )
ON MyDB_FG1;
GO
