TPC-H生成数据集并导入数据库

一.生成数据集
1.下载TPC-H压缩包

下载地址：http://www.tpc.org/tpc_documents_current_versions/current_specifications.asp

2.解压TPC-H的压缩包,进入dbgen文件夹,找到tpch.sln文件，用visual studio打开。

3.在工程处右键dbgen，选择生成,执行完毕

4.此时，在dbgen文件夹下，出现了debug文件夹,在debug文件夹中，找到dbgen.exe的文件。copy到上一层目录，也就是dbgen文件夹中。

5.在dbgen文件夹下，打开dos界面。(在文件地址栏输入cmd)。输入命令dbgen -h

5.运行完后直接输入dbgen -vf -s XXX就可以生成你想要的数据了。这里的XXX表示想要生成的数据量(单位GB)

6.生成结束后，就能在dbgen文件夹下面看到生成的数据集了。生成完毕(20GB)

二.导入数据

1.新建一个数据库用于导入数据

2.建表sql

3.建立表约束

4.导入数据

5.查看导入的数据

6.TPC-H数据集表关系图

三.SQL语句

use Big
