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);
?>
上の例の出力は、 たとえば以下のようになります。
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 ) )
