爲什麼我不能爲我的帳戶表放棄這個FOREIGN KEY約束？

Question

我有上有這個FOREIGN KEY約束的accounts表：

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

我想刪除這個限制，但每次我試圖執行以下命令：

ALTER TABLE accounts DROP CONSTRAINT edits_account_id_fkey1; 

我得到這個錯誤：

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

它顯然存在。我正在用\d accounts命令來查看它。這是爲什麼發生？

該約束被放置在桌子上edits，但是你正在改變表accounts。在查詢中將accounts更改爲edits，然後它將起作用。
