Thinkphp 3.2.3 多表事务

$Model = M();
$Model->startTrans();
$userRes = $Model->table('test_user')->add(['name'=>'admin']);
$keyRes  = $Model->table('test_key')->add(['key'=>'test']);
$taskRes = $Model->table('test_task')->add(['task'=>'test']);
if (userRes && $keyRes && $taskRes) 
    $Model->commit();
else
    $Model->rollback();

ENGINE=MyISAM  会导致回滚失败

需要修改成 InnoDB 引擎：

mysql> alter table `test_user` engine=innodb;
