Ejemplo #1 mysql_xdevapi\CollectionFind::limit() 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");
$result = $collection
->find('job like :job and age > :age')
->bind(['job' => 'Butler', 'age' => 16])
->sort('age desc')
->limit(1)
->execute();
var_dump($result->fetchAll());
?>El resultado del ejemplo sería algo similar a:
array(1) {
[0]=>
array(4) {
["_id"]=>
string(28) "00005b6b536100000000000000f3"
["age"]=>
int(42)
["job"]=>
string(6) "Butler"
["name"]=>
string(8) "Reginald"
}
