在 phpMyAdmin 中添加约束

Adding constraints in phpMyAdmin(在 phpMyAdmin 中添加约束)

问题描述

我觉得我很愚蠢，但我在 phpMyAdmin 界面上找不到任何地方来向外键添加约束，例如级联删除

I feel like I'm being stupid, but I can't find anywhere on the phpMyAdmin interface to add constraints to foreign keys e.g. CASCADE ON DELETE

我在此处和 phpMyAdmin wiki 上寻找过类似的问题，但找不到任何相关信息.

I've looked for similar questions on here and on the phpMyAdmin wiki but I can't find anything about it.

我意识到我可以通过查询界面来做到这一点，但我想知道如何通过图形界面来做到这一点.

I realise I could do this via the query interface, but I'd like to know how to do it through the graphical interface.

First, you should have your storage engine as InnoDB. Then select a table and go to 'Structure' tab.

在表格下方，您将看到关系视图"，单击它.从那里你可以添加约束.

Under the table you will see 'Relation view', click it. From there you could add constraints.
