RowResult::getWarnings — Get warnings from last operation
Retrieve warnings from the last RowResult operation.
此函數沒(méi)有參數。
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.
示例 #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);
?>
以上例程的輸出類(lèi)似于：
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
)
)
