我正在使用PDO运行多个查询.如果第二个查询失败,则抛出异常.
$db = new PDO("MysqL:host=localhost;dbname=test",'root','');
$db->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
$sql = "
DELETE FROM car;
INSERT INTO car(name,type) SELECT name,from FROM vehicle;
";
try {
$db->exec($sql);
}
catch (PDOException $e)
{
echo $e->getMessage();
die();
}
上面的代码执行时没有抛出异常.
我在使用准备好的声明时找到了答案.循环遍历所有行集后,我可以使用$stmt-> errorInfo()检查上次执行的查询是否导致错误.

$db->setAttribute(PDO::ATTR_EMULATE_PREPARES,1);
$sql = "
DELETE FROM car;
INSERT INTO car(name,from FROM vehicle;
";
$stmt = $db->prepare($sql);
$stmt->execute();
$i = 0;
do {
$i++;
} while ($stmt->nextRowset());
$error = $stmt->errorInfo();
if ($error[0] != "00000") {
echo "Query $i Failed: " . $error[2];
die();
}
