DocResult::getWarnings — 获取上次操作的警告
此函数没有参数。
上次操作的警告对象数组。每个对象都定义了一个错误 'message'、错误 'level' 和错误 'code'。如果不存在错误，则返回一个空数组。
示例 #1 mysql_xdevapi\DocResult::getWarnings() 示例
<?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");
// 产生一个 DocResult 对象
$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());
?>以上示例将输出类似于以下内容
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
)
)
