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

问题

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

$connection = Yii::app()->db;
$transaction=$connection->beginTransaction();
try {

    $q = "INSERT INTO `someTable1` .... ";      
    $connection->createCommand($q)->execute(); // Single Row Inserted

    // HERE!! How to get the last insert ID from query above

    $q = "INSERT INTO `someTable2` ....
          WHERE id = LAST_INSERT_ID_FROM_FIRST_QUERY ";
    $connection->createCommand($q)->execute();

    $transaction->commit();

} catch (Exception $e) {
    // react on exception   
    $trans->rollback();
} 

What would be the most suitable way to do that?

回答1:

$lastInsertID = $connection->getLastInsertID();

回答2:

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

$lastInsertID = $connection->getLastInsertID();

or

$lastInsertID = $connection->lastInsertID;

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;
}
