$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();
$schema = $session->getSchema("addressbook");
$create = $schema->createCollection("people");
$create->add('{"name": "Alfred", "age": 18, "job": "Butler"}')->execute();
$create->add('{"name": "Reginald", "age": 42, "job": "Butler"}')->execute();
// ...
$collection = $schema->getCollection("people");
// 產生一個 DocResult 物件
$result = $collection
->find('job like :job and age > :age')
->bind(['job' => 'Butler', 'age' => 16])
->sort('age desc')
->execute();
if (!$result->getWarningsCount()) {
echo "發生錯誤：\n";
print_r($result->getWarnings());
exit;
}
var_dump($result->fetchOne());
