范例
Example #1 mysql_xdevapi\Collection::getOne() 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");
$collection = $schema->createCollection("people");
$result = $collection->add('{"name": "Alfred", "age": 42, "job": "Butler"}')->execute();
// A unique _id is (by default, and recommended) generated by MySQL Server
// This retrieves the generated _id's; only one in this example, so $ids[0]
$ids = $result->getGeneratedIds();
$alfreds_id = $ids[0];
// ...
print_r($alfreds_id);
print_r($collection->getOne($alfreds_id));
?>
以上例程的输出类似于:
00005b6b536100000000000000b1 Array ( [_id] => 00005b6b536100000000000000b1 [age] => 42 [job] => Butler [name] => Alfred )
