mysql插入並在準備好的語句中選擇

Question

如何將mysql插入和select語句組合到一個準備好的語句中？當我點擊「複製」按鈕時，這部分代碼是否可以幫助我將信息複製到數據庫中？

謝謝。

INSERT INTO assignment_speeches_copy (id, subject, body, tags, image) 
SELECT * FROM assignment_speeches 
WHERE id = $id"; 

$stmt = $mysqli->prepare("INSERT INTO assignment_speeches_copy VALUES (?,?,?,?,?)"); (how do I continue?)

您不必組合任何東西。 INSERT ... SELECT是一個簡單的聲明....

$stmt = $mysqli->prepare(
    "INSERT INTO assignment_speeches_copy (id, subject, body, tags, image) 
     SELECT (id, subject, body, tags, image) 
      FROM assignment_speeches 
      WHERE id = ?" 
    );
