如何從該查詢中刪除結果？

Question

如何從數據庫中刪除此查詢的結果？ 你們能幫助我，請

SELECT v.type 
FROM poll_answers 
JOIN vote_types v ON poll_answers.vote_id = v.id 
JOIN poll_questions q ON q.id = poll_answers.question_id 
WHERE q.referendum_id =1 

我試圖通過一個將其刪除ID之一，但我曾與外鍵的問題，所以我想一步

刪除步謝謝

試這樣的：

delete poll_answerpoll_answer,v,q, 
FROM poll_answers 
JOIN vote_types v ON poll_answers.vote_id = v.id 
JOIN poll_questions q ON q.id = poll_answers.question_id 
WHERE q.referendum_id =1 

編輯

mysql> delete poll_answers,v,q 
    -> FROM poll_answers 
    -> JOIN vote_types v ON poll_answers.vote_id = v.id 
    -> JOIN poll_questions q ON q.id = poll_answers.question_id 
    -> WHERE q.referendum_id =1;
