使用具有多個外鍵的表創建 sql 數據庫腳本

[英]Creating an sql database script with tables with multiple foreign keys

 原文  2020-05-13 20:12:16  8   1    mysql/ foreign-keys

問題描述

對於數據庫創建練習，我正在嘗試使用以下腳本創建一個數據庫，該腳本會給出錯誤：

錯誤代碼：1005。無法創建表qr_bottle 。 invoice (errno: 150 "外鍵約束格式不正確")

我不確定是否理解這個問題，我是否應該創建沒有外鍵的所有表並在創建所有表后更改表以添加鍵？

你的table order product和invoice是interlinkt的，只能在引用表創建后添加外文，所以要在創建引用表后修改表
