DocResult::getWarnings — Get warnings from last operation
Fetches warnings generated by MySQL server's last operation.
Questa funzione non contiene parametri.
An array of Warning objects from the last operation. Each object defines an error 'message', error 'level', and error 'code'. An empty array is returned if no errors are present.
Example #1 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());
?>
Il precedente esempio visualizzerà qualcosa simile a:
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 ) )
