Example #1 mysql_xdevapi\Collection::removeOne() example


$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);

$result->getAffectedItemsCount()) {
"Alfred with id $alfred_id was not removed.";
} else {
"Goodbye, Alfred, you can take _id $alfred_id with you.";

Il precedente esempio visualizzerĂ  qualcosa simile a:

Goodbye, Alfred, you can take _id 00005b6b536100000000000000cb with you.
