can'；t在MySQL数据库中创建最后两个表

还请帮助我查找ER模型中的错误（我不允许有超过6个表）

---

我得到的答案是，外键名称在表中应该是唯一的……我使用了上一个表中已经使用过的外键名称。

ORDER

是SQL关键字和MySQL保留字。我建议所有表格都用复数命名（即“订单”而不是“订单”，“卖方”而不是“卖方”）。更少的保留字是复数。谢谢，我能够创建“订单”表，但仍然无法创建最后一个。修复外键引用。顺便说一下，我投票结束这些问题。很明显，

ORDER

是一个保留字，因为它是一个常见的SQL关键字。你是说这个修复吗？命令到命令…但是我。仍然无法创建表我无法修复上一个表中的第二个和第三个外键引用（ARTWORK\u ID和SELLER\u ID）
