Question

我有一个accounts表，其上有FOREIGN KEY个约束：

TABLE "edits" CONSTRAINT "edits_account_id_fkey1" FOREIGN KEY (account_id) REFERENCES accounts(id) ON DELETE CASCADE

我想放弃这个约束，但每次我尝试执行以下命令时都会这样做：

ALTER TABLE accounts DROP CONSTRAINT edits_account_id_fkey1;

我收到此错误：

ERROR:  constraint "edits_account_id_fkey1" of relation "accounts" does not exist

显然存在。我正在使用\d accounts命令查看它。为什么会这样？

Answer 1

约束放在表edits上，但您正在更改表accounts。将查询中的accounts更改为edits，然后就可以了。

为什么我不能为帐户表删除此FOREIGN KEY约束？
