Laravel 4无法运行完整的原始查询。

我想使用laravel的DB类来执行mysql查询，但是Laravel提供的所有函数都不起作用。
这些都不起作用：DB::statement() / DB::select() / DB::raw() / DB::update() / DB::select(DB::raw())
这是我想要查询的代码：
DROP TABLE users;

CREATE TABLE `users` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `u_username` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `u_email` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `password` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `u_regdate` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
  `u_birthday` date NOT NULL DEFAULT '0000-00-00',
  `u_lastlogin` int(11) NOT NULL,
  `u_logcout` int(11) NOT NULL DEFAULT '0',
  `u_level` tinyint(1) NOT NULL DEFAULT '0',
  `u_language` tinyint(1) NOT NULL DEFAULT '0',
  `u_status` tinyint(1) NOT NULL DEFAULT '0',
  `u_gender` tinyint(1) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

INSERT INTO users VALUES("1","admin","admin@example.com","$2y$08$9sBJh7iyF9Yr6xvsieNmBOsotGPBkZFydVjb/Yk5Fzh4IGBVo7Je6","0000-00-00 00:00:00","0000-00-00","0","0","9","0","0","0");
INSERT INTO users VALUES("2","moderator","mod@example.com","$2y$08$15/tIKPM/8gATSzkmey5tuAA/PL4lJeFq7liTETyz0h1dkOotwp3G","0000-00-00 00:00:00","0000-00-00","0","0","0","0","0","0");
INSERT INTO users VALUES("3","helper","help@example.com","$2y$08$nTtZU9/UBeRLbYJRO/XwCe2D/B57ofx2bCN8vGEiHkqO.bPra0WT6","0000-00-00 00:00:00","0000-00-00","0","0","0","0","0","0");
INSERT INTO users VALUES("4","dude12","dude@example.com","$2y$08$y0JweKtWxJFRF7Ko8q0zkODY.EWEKJ.CR1dDco6aCJh8ssKdzQ6RC","0000-00-00 00:00:00","0000-00-00","0","0","0","0","0","0");
INSERT INTO users VALUES("5","girl1","girl@example.com","$2y$08$UKjJzxDuYW7upqeLsm1VOOo2jUoqMaai0/1jFxvLDzC6eWjin3yOe","0000-00-00 00:00:00","0000-00-00","0","0","0","0","0","0");

我已经查看并尝试了这两个主题中的方法，但都没有起作用： 无法在Laravel 4中运行原始查询 Laravel 4如何运行原始SQL 当使用“DB :: select（DB :: raw（$ query））”或DB :: statement执行时返回错误：

你能展示一下使用DB类执行查询时出现的错误吗？ - saran banerjee
将错误返回添加到主问题中。当我尝试使用phpmyadmin执行查询时，它可以完美地工作。 - Omer M.

@OmerM。你是如何在你的系统中使用DB类的？你是创建了一个模型还是直接在控制器中调用它？ - Volatil3

@Volatil3 对于这个项目，我在 PHP 命令类中使用了 DB 类。我想创建一个工匠命令，以便可以使用它来导出和导入我的数据库。您可以在整个项目中的控制器或模型中使用 DB 类。 - Omer M.

从数据库中删除用户表，然后尝试以下操作并告诉我是否可以正常工作：
DB::insert('CREATE TABLE `users` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `u_username` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `u_email` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `password` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `u_regdate` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
  `u_birthday` date NOT NULL DEFAULT '0000-00-00',
  `u_lastlogin` int(11) NOT NULL,
  `u_logcout` int(11) NOT NULL DEFAULT '0',
  `u_level` tinyint(1) NOT NULL DEFAULT '0',
  `u_language` tinyint(1) NOT NULL DEFAULT '0',
  `u_status` tinyint(1) NOT NULL DEFAULT '0',
  `u_gender` tinyint(1) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci');

//and so on for all the other queries.
DB::query在laravel 4中不存在，所以我使用了DB::insert并且它起作用了。我猜想同时执行多个查询是不可能的，但逐个执行它们是可以工作的。 - Omer M.
是的，你需要逐个执行查询，感谢告诉我在 Laravel 4 中不存在 DB::query。我会将答案更改为使用 insert()。 - saran banerjee

刚刚发现有一个执行原始mysql代码的函数：DB :: unprepared（$ code）; https://github.com/laravel/framework/pull/54 - Omer M.

这段代码怎么样？ 我发现使用迁移和数据库填充非常有用 - 特别是在部署方面。
Schema::create('users', function($table){
    $table->increments('id');
    $table->string('u_username');
    $table->string('u_email');
    $table->string('password');
    $table->datetime('u_regdate');
    $table->date('u_birthday');
    $table->integer('u_lastlogin');
    $table->integer('u_logcout')->default(0);
    $table->tinyinteger('u_level')->default(0);
    $table->tinyinteger('u_language')->default(0);
    $table->tinyinteger('u_status')->default(0);
    $table->tinyinteger('u_gender')->default(0);
});


// Repeat this for other users as well
User::create([
    'u_username' =>     'admin',
    'u_email' =>        'admin@example.com',
    'password' =>       Hash::make('users-password'),
    'u_regdate' =>      date('Y-m-d H:i:s'),
    'u_birthday' =>     '1980-01-01',
    'u_lastlogin' =>    0,
    'u_logcout' =>      0,
    'u_level' =>        9,
    'u_language' =>     0,
    'u_status' =>       0,
    'u_gender' =>       0,
]);
