导入测试数据集

安装完GreatSQL数据库后，如果是用于教学或测试场景，可以导入几个通用的测试数据集，主要有：

  • Employees sample database，一个模拟
  • world sample database
  • Sakila sample database

1. 下载测试数据集压缩包

上述三个测试数据集下载地址分别是：

分别下载到本地，并解压缩到 /tmp/testdb 目录下：

  1. $ ls -l /tmp/testdb
  3. drwxr-xr-x 2  500  500      100 Aug  1 06:06 sakila-db  #<--sakila 测试数据集
  4. -rw------- 1 root root   732290 Aug  1 06:06 sakila-db.tar.gz
  5. drwx------ 4 root root      460 Aug 29 15:33 test_db    #<--employees 测试数据集
  6. -rw------- 1 root root 35607473 Aug 29 15:32 test_db-1.0.7.tar.gz
  7. drwxr-xr-x 2  500  500       60 Aug  1 06:06 world-db   #<--world 测试数据集
  8. -rw------- 1 root root    92916 Aug  1 06:06 world-db.tar.gz

2. 导入测试数据集

2.1 导入employees数据集

employees测试数据文件包中提供了导入方法说明，基本上照着做就行：

  1. $ cd /tmp/testdb/test_db
  2. $ cat README.md
  3. ...

开始导入（在这里，采用具有最高权限的root账户导入，所以略过创建测试账户这个环节，下同）：

  1. $ mysql -f < employees.sql
  2. INFO
  3. CREATING DATABASE STRUCTURE
  4. INFO
  5. storage engine: InnoDB
  6. INFO
  7. LOADING departments
  8. INFO
  9. LOADING employees
  10. INFO
  11. LOADING dept_emp
  12. INFO
  13. LOADING dept_manager
  14. INFO
  15. LOADING titles
  16. INFO
  17. LOADING salaries
  18. data_load_time_diff
  19. 00:02:28

导入完成后，还可以执行校验程序，确认导入的结果无误：

  1. greatsql> SOURCE /tmp/testdb/test_db/test_employees_md5.sql;

看起来验证无误。

2.2 导入world数据集

执行下面的命令导入world数据集：

  1. greatsql> SOURCE /tmp/testdb/world-db/world.sql;
  2. ...
  3. greatsql> SELECT COUNT(*) FROM city;
  4. +----------+
  5. | count(*) |
  6. +----------+
  7. |     4079 |
  8. +----------+
  10. greatsql> SELECT COUNT(*) FROM country;
  11. +----------+
  12. | count(*) |
  13. +----------+
  14. |      239 |
  15. +----------+
  17. greatsql> SELECT COUNT(*) FROM countrylanguage;
  18. +----------+
  19. | count(*) |
  20. +----------+
  21. |      984 |
  22. +----------+

导入完毕。

导入完毕。

接下来就可以运行查询和测试了。
