How to get last inserted ids in laravel

问题

I am inserting multiple rows at the same time, say 2 rows

$multiple_rows = [
    ['email' => 'taylor@example.com', 'votes' => 0],
    ['email' => 'dayle@example.com', 'votes' => 0]
];
DB::table('users')->insert($multiple_rows);

How can I get those inserted ids.

I am doing it, this way for now.

foreach($multiple_rows as $row){
  DB::table('users')->insert($row);
  $record_ids[] = DB::getPdo()->lastInsertId();
}

Any other good way to do it, without inserting single row each time.

回答1:

You could do something like the following:

$latestUser = DB::table('users')->select('id')->orderBy('id', 'DESC')->first();

$multiple_rows = [
    ['email' => 'taylor@example.com', 'votes' => 0],
    ['email' => 'dayle@example.com', 'votes' => 0]
];

DB::table('users')->insert($multiple_rows);

$users = DB::table('users')->select('id')->where('id', '>', $latestUser->id)->get();

If you really need all the inserted ID's

$dataArray = [
    ['name' => 'ABC'],
    ['name' => 'DEF']
];

$ids = [];

foreach($dataArray as $data)
{
     $ids[] = DB::table('posts')->insertGetId($data);

}

To get all id with a massive insertion I think the good way is to first get the last id in the table, make the massive insertion and get the last id. In theory they must follow, unless there has been an insertion from another connection. To avoid that the solution is a transaction.
