use Migliori\PowerLitePdo\Query\QueryBuilder;

$container = require_once __DIR__ . '/../src/bootstrap.php';
$queryBuilder = $container->get(QueryBuilder::class);

Method Signature

public function transactionCommit(): bool

$queryBuilder->transactionBegin();

// Perform some database operations...

$queryBuilder->transactionCommit(); // Commit the transaction

$queryBuilder->transactionBegin();

try {
