BaseResult::getWarnings — Fetch 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\RowResult::getWarnings() example
<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("CREATE DATABASE foo")->execute();
$session->sql("CREATE TABLE foo.test_table(x int)")->execute();
$schema = $session->getSchema("foo");
$table = $schema->getTable("test_table");
$table->insert(['x'])->values([1])->values([2])->execute();
$res = $table->select(['x/0 as bad_x'])->execute();
$warnings = $res->getWarnings();
print_r($warnings);
?>Il precedente esempio visualizzerà qualcosa simile a:
Array
(
[0] => mysql_xdevapi\Warning Object
(
[message] => Division by 0
[level] => 2
[code] => 1365
)
[1] => mysql_xdevapi\Warning Object
(
[message] => Division by 0
[level] => 2
[code] => 1365
)
)
