我想使用laravel的DB类来执行mysql查询，但laravel提供的函数都不起作用。
这些都不起作用：DB:：stat（）/DB:：select（）/DC:：raw（）/DM:：update（）/DD:：select
这是我想查询的代码：
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");
我也从这两个主题中寻找并尝试了方法，但什么都不起作用：
无法运行-查询-行程-4
laravel-4-如何运行原始-sql
使用"DB:：select（DB:：raw（$query））"或DB:：statement:执行时返回错误

像我在问题中提供的那样执行SQL代码可以使用执行
DB::unprepared( $code );
我希望这能帮助那些与我有同样问题的人：D
查看laravel问题时发现的答案
从数据库中删除users表，然后尝试此操作并让我知道它是否有效：
DB::insert('CREATE TABLE `users` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`u_username` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`u_email` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`password` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`u_regdate` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
`u_birthday` date NOT NULL DEFAULT '0000-00-00',
`u_lastlogin` int(11) NOT NULL,
`u_logcout` int(11) NOT NULL DEFAULT '0',
`u_level` tinyint(1) NOT NULL DEFAULT '0',
`u_language` tinyint(1) NOT NULL DEFAULT '0',
`u_status` tinyint(1) NOT NULL DEFAULT '0',
`u_gender` tinyint(1) NOT NULL DEFAULT '0',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci');
//and so on for all the other queries.
这个代码怎么样？我发现使用迁移&数据库种子-特别是用于部署。
Schema::create('users', function($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,
]);
