我在网上看到，问题可能与外键有关（尽管我检查过了，看起来不错……），或者与engine=innodb声明有关。我试着用这个问题的答案，但没有成功，或者我不太明白答案（我交换了engine=innodb；使用engine=innodb default charset=utf8 collate=utf8\u unicode\u ci；）我还检查了我的mysql版本，我使用10.1.35-mariadb，它应该有不可见的索引可用（如我链接的问题的另一个答案所述）。
我没有mysql的经验，所以如果这是一个非常简单的问题，我很抱歉。感谢您的帮助：）

好吧，有两个不同的问题。dialogueflow表中无符号int“status”的默认值是“created”（我从使用枚举改为使用外键，忘记删除旧的默认值），所以 Status int unsigned not null默认值“created”
另一个问题似乎与索引有关。当移除所有组件时：
索引 fk_MultiStep_Dialogues_Status1_idx ( Status asc）可见
索引 fk_Nodes_MultiStep_Dialogues_idx ( MultiStep_Dialogue asc）可见，
索引 fk_Nodes_Node_Types1_idx ( Node_Type asc）可见，
诸如此类，似乎奏效了。我真的不明白为什么会这样，但现在我将删除外键上的索引，并在以后修复它。
