mysql - INSERT INTO 从 select 语句中删除 mysql 中的一个字段

Question

除了我想要从 $_POST["user"] 插入值的一个字段之外，有什么方法可以插入 select 语句中的大部分值吗？我需要两个查询才能执行此操作吗？

$sql = "INSERT INTO `TAB1` (name,category, brand, image_url,big_img)
        SELECT a.name,b.category, b.brand, a.image_url,a.big_img
        FROM `mTaB2` a INNER JOIN `mTab3` b
        ON a.tid = b.id 
        WHERE a.id = ?           
       ";
$users = $dbh->prepare($sql);
$users->bindValue(1, $_POST["id"]);
$result = $users->execute();          

...............

$sql = "INSERT INTO `TAB1` (user)
        VALUES(?)
       ";

$users = $dbh->prepare($sql);
$users->bindValue(1, $_POST["user"]);
$result = $users->execute();

我认为这样的事情会起作用:

$sql = "INSERT INTO `TAB1`(user, name, category, brand, image_url, big_img)
        SELECT ?, a.name, b.category, b.brand, a.image_url, a.big_img
        FROM `mTaB2` a INNER JOIN `mTab3` b
        ON a.tid = b.id 
        WHERE a.id = ?           
       ";
$users = $dbh->prepare($sql);
$users->bindValue(1, $_POST["user"]);
$users->bindValue(2, $_POST["id"]);
