Beispiel #1 mysql_xdevapi\Collection::removeOne() 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": 18, "job": "Butler"}')->execute();
// Normally the _id is known by other means,
// but for this example let's fetch the generated id and use it
$ids = $result->getGeneratedIds();
$alfred_id = $ids[0];
$result = $collection->removeOne($alfred_id);
if(!$result->getAffectedItemsCount()) {
echo "Alfred with id $alfred_id was not removed.";
} else {
echo "Goodbye, Alfred, you can take _id $alfred_id with you.";
}
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
Goodbye, Alfred, you can take _id 00005b6b536100000000000000cb with you.
