@xiaofan2 没有校验 update 返回值。做的类似这样的操作
Db::transaction(function () {

//用户账号
$money = 10000;
$accountModel = new Account();
$accountModel->where('uid', 0)
->update([
'dream_fund' => $money,
]);

$billData = [
'uid' => 0,
'money' => 0,
'itime' => time(),
'utime' => time(),
];
$this->model->data($billData);
$this->model->save();
});
