我理解INERT IGNORE 这个方法是任意冲突忽略，但是 ON CONFLICT DO NOTHING 需要明确指定冲突的列或约束

I understand that INERT IGNORE is a method that ignores any conflicts, but ON CONFLICT DO NOTHING requires explicitly specifying conflicting columns or constraints.

我试了不要指定约束就可以完成的，

I tried it and it can be done without specifying constraints.
