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
