How to iterate over all rows in a table in a migration?

    The bottom line is that in the migration you need to iterate over all the lines and change one field in each construction site. But I can't find something as they move in migrations to make such a massive update

    I'm not sure if this is the best option, but you can always use the ActiveRecord model for this - for example, if you need to update the 'status' field in the 'records' table:

    public function safeUp()
    $modelsQuery = Record::find();

    /** @var Record $record */
    foreach ($modelsQuery->each() as $record) {
    $record->status = 'new status';
