Example #1 mysql_xdevapi\DocResult::fetchOne() 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");
$create->add('{"name": "Alfred", "age": 18, "job": "Butler"}')->execute();
$create->add('{"name": "Reginald", "age": 42, "job": "Butler"}')->execute();
// ...
$collection = $schema->getCollection("people");
// Yields a DocResult object
$result = $collection
->find('job like :job and age > :age')
->bind(['job' => 'Butler', 'age' => 16])
->sort('age desc')
->execute();
var_dump($result->fetchOne());
?>Il precedente esempio visualizzerà qualcosa simile a:
array(4) {
["_id"]=>
string(28) "00005b6b53610000000000000125"
["age"]=>
int(42)
["job"]=>
string(6) "Butler"
["name"]=>
string(8) "Reginald"
}
