1.创建数据库TCP-H

（1）右键“数据库”，点击“新建数据库”即可

（2）用sql语言创建，此处以创建数据库DB_test为例，代码如下：

use master;go--检查在当前服务器系统中的所有数据里面是否有该数据库
IF EXISTS(SELECT * FROM sysdatabases WHERE NAME='DB_test')
--如果有删除该数据库DROP DATABASE DB_test
-- 创建该数据库CREATE DATABASE DB_test  ---DB_Yun 数据名称ON PRIMARY(NAME='DB_test',  --主数据文件的逻辑名FILENAME='D:developsqldataDB_test.mdf', --主数据文件存储位置SIZE=16MB,  --主数据文件的初始大小FILEGROWTH=8MB, --每次增容时增加的容量大小MAXSIZE=UNLIMITED  --增量速度 unlimited无限制)LOG  ON( NAME='DB_test.LDF',  --日志文件FILENAME='D:developsqldataDB_test.ldf', --日志文件存储位置SIZE=16MB,  --日志文件初始大小FILEGROWTH=8MB,  --日志文件每次增加的容量大小MAXSIZE=UNLIMITED

（3）创建成功

2.进行数据的导入

（1）下载csv文件

（2）进行导入，导入代码如下
