mysql插入并在准备好的语句中选择

Question

我如何将mysql insert和select语句组合到一个准备好的语句中？ 单击“复制”按钮时，这部分代码是否可以帮助我将信息复制到数据库中？

谢谢。

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?)

Answer 1

您无需结合任何东西。 INSERT ... SELECT是一个简单的语句。

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