在 Laravel 中使用 Eloquent 更新记录时如何使用原始 SET 语句？

Question

Is it possible to use Eloquent to turn the following SQL statement into PHP codes in Laravel?

UPDATE my_table SET column1 = price*qty*?, column2 = 0 WHERE row_id = ?

If it's not possible with Eloquent (I couldn't find it in Laravel's documentation), using query builder would be acceptable too.

Try this:

$item = Item::where('row_id', $row_id)->first();
$item->update(['column1' => $item->price * $item->qty, 'column2' => 0]);
