将数据插入到表一次

Question

这是我的代码

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

我从另一个表获得的数据与此查询

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) 

本声明将数据从测验组复制到用户表
