How to detect the last insert ID within a transaction in Yii using DAO?

Question

That\'s the source code, I need to detect the ID (see the marked position between the two queries below).

$connection = Yii::app()->db;
$transaction=$conn         


        

Answer 1

$lastInsertID = $connection->getLastInsertID();

Answer 2

you can try both way,here getLastInsertID is method and lastInsertID is property

$lastInsertID = $connection->getLastInsertID();

or

$lastInsertID = $connection->lastInsertID;

Answer 3

i created this to solve that issue

public static function getAutoIncrement($table_name)
{
    $q = new Query();
    $res = $q->select("AUTO_INCREMENT")
        ->from('INFORMATION_SCHEMA.TABLES')
        ->where("TABLE_SCHEMA = DATABASE() AND TABLE_NAME = '" . $table_name . "'")
        ->one();
    if ($res)
        return $res["AUTO_INCREMENT"];
    return false;
}
