mysql - MySQL 外部约束 ON DELETE CASCADE

Question

我想知道我是否正确实施了它，或者是否相反。

所以我有3张桌子：

TableParent,TableChild和AnotherTable

TableParent有个PK叫id

TableChild并且AnotherTable有一个 PK 也称为id它也是一个 FK 约束TableParent.id，它有ON DELETE CASCADE

我对其建模认为，如果我删除 中的一行，则其中的TableParent每一行都将被自动删除。TableChildAnotherTable

它是这样工作的吗？（使用 MySQL，引擎 InnoDB）

Check out this quesion/answer. I think it has all you need and more on this issue.

MySQL foreign key constraints, cascade delete

I could retype it all, but that seems redundent.
