以下示例在 SQL Server 实例上创建了一个数据库。该数据库包括一个主数据文件、一个用户定义文件组和一个日志文件。主数据文件在主文件组中,而用户定义文件组包含两个次要数据文件。ALTER DATABASE 语句将用户定义文件组指定为默认文件组。然后通过指定用户定义文件组来创建表。
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
