/* v 9.08
SQL脚本的一些要点:
0.存储引擎使用 InnoDB, 字符集改为 utf8mb4 以更好地支持中文.
1.所有表名所使用的英文字母都改为小写(后续章节中,SQL查询中的表名也需要相应修改为小写)
2.所有列名所使用的英文字母确认为小写(后续章节中,SQL查询中的列名也需要相应修改为小写)
3.存在问题的数据, 例如 inventoryproduct 表的inventory_id列应为P开头的, 已修正为正确的数据.
4.需测试SQL脚本在命令行及各个客户端中是否能被正确执行.
  * MySQL Workbench 已测试通过
  * DBeaver 已测试通过(使用"执行SQL脚本(CTR+x)")
  * HeidiSQL 已测试通过
  * navicat 已测试通过
  * sqlyog 已测试通过
  * 命令行 测试未通过. 插入中文数据时提示" Data too long for column 'product_name' at row 1"
