一次将数据插入表中

Question

这是我的代码

 echo    '<input type="submit" name="submit">';

我使用此查询从另一个表中获取数据

if($_POST['submit'])
 {
    $sql = mysql_query('SELECT q.username, q.firstanme,q.lastname FROM quizgroup q');
    foreach($sql as $s)
     {
        $username = $s->username;
        $firstname = $s->firstname;
        $lastname = $s->lastname;
        $sql = mysql_query('INSERT INTO user(username,firstname,lastname) VALUES('.$username.','.$first.','.$last.')');
     }
 }

Answer 1

试试这个

insert into user (SELECT username, firstanme, lastname FROM quizgroup)

此语句将数据从测验组复制到用户表

复制数据时不要使用“values”关键字
