Db::startTrans(); //启动事务
        try {
            $newUserId = Db::name('user')->insertGetId($data); //新用户id我怎么打印他要执行的sql语句是什么，我 想看看这条语句哪里错了。
我看了一下日志文件，没有这个记录。

日志文件

[ info ] [ DB ] INIT mysql
[ sql ] [ DB ] CONNECT:[ UseTime:0.019327s ] mysql:host=localhost;port=3306;dbname=mmm;charset=utf8
[ sql ] [ SQL ] SHOW COLUMNS FROM `mmm_user` [ RunTime:0.017545s ]
[ sql ] [ SQL ] SELECT `user_name` FROM `mmm_user` WHERE `user_name` = 'www' LIMIT 1 [ RunTime:0.002523s ]

[ sql ] [ SQL ] SELECT `category_user_id` FROM `mmm_category` WHERE `category_user_id` = 1000 LIMIT 1 [ RunTime:0.003109s ]

完全看不到这个insert语句是什么。
