Example 5.80 mysql_xdevapi\DocResult::getWarnings
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:
There was an error: Array ( [0] => mysql_xdevapi\Warning Object ( [message] => Something bad and so on [level] => 2 [code] => 1365 ) [1] => mysql_xdevapi\Warning Object ( [message] => Something bad and so on [level] => 2 [code] => 1365 ) )
