$session->sql("DROP DATABASE IF EXISTS dbtest")->execute();
$session->sql("CREATE DATABASE dbtest")->execute();
$session->sql("CREATE TABLE dbtest.workers(name text, age int, job text)")->execute();
$session->sql("INSERT INTO dbtest.workers values ('John', 42, 'bricklayer'), ('Sam', 33, 'carpenter')")->execute();
$schema = $session->getSchema("dbtest");
$table = $schema->getTable("workers");

print_r($rows);
?>
