    示例 #1 mysql_xdevapi\Result::getGeneratedIds() example

    <?php
    $session     = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
    $session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
    $session->sql("CREATE DATABASE addressbook")->execute();

    $schema = $session->getSchema("addressbook");
    $create = $schema->createCollection("people");

    $collection = $schema->getCollection("people");

    $result = $collection->add(
    '{"name": "Bernie",
    "jobs": [{"title":"Cat Herder","Salary":42000}, {"title":"Father","Salary":0}],
    "hobbies": ["Sports","Making cupcakes"]}'    ,
    '{"name": "Jane",
    "jobs": [{"title":"Scientist","Salary":18000}, {"title":"Mother","Salary":0}],
    "hobbies": ["Walking","Making pies"]}'    )->execute();

    $ids = $result->getGeneratedIds();
    var_dump($ids);
    ?>

  string(28) "00005b6b53610000000000000064"
  [1]=>
  string(28) "00005b6b53610000000000000065"
}
