Examples
Example #1 mysql_xdevapi\DocResult::getWarningsCount() 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 = $collection
->find('job like :job and age > :age')
->bind(['job' => 'Butler', 'age' => 16])
->sort('age desc')
->execute();
if (!$result->getWarningsCount()) {
echo "There was an error:\n";
print_r($result->getWarnings());
exit;
}
var_dump($result->fetchOne());
?>
The above example will output something similar to:
array(4) { ["_id"]=> string(28) "00005b6b53610000000000000135" ["age"]=> int(42) ["job"]=> string(6) "Butler" ["name"]=> string(8) "Reginald" }
