创建数据库[编辑]

创建的每个数据库都会创建相应的文件:

  • Master Database File (.mdf)
  • Log Database File (.ldf)
CREATE DATABASE [MyDB] ON  PRIMARY 
( NAME = N'MyDB', FILENAME = N'D:\DATASQL\MSSQL10.MSSQLSERVER\MSSQL\DATA\MyDB.mdf' , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
 LOG ON 
( NAME = N'MyDB_log', FILENAME = N'D:\DATASQL\MSSQL10.MSSQLSERVER\MSSQL\DATA\MyDB_log.ldf' , MAXSIZE = 2048GB , FILEGROWTH = 10%)
GO

读取[编辑]

显式指明数据库:

USE MyDB;
SELECT * FROM MyTable;

或使用全路径:

SELECT * FROM [MyDB].[dbo].[MyTable];
