如何检查laravel更新表？

Question

下面我需要更新users表中的一些列。我在代码中使用laravel查询构建器。我想知道用户表是否有更新？

 DB::table('users')
            ->where('id',2)
            ->update
            ([
                'first_name'            => trim($validate->firstName),
                'capital'               => trim($validate->capital),
                'last_name'             => trim($validate->lastName),
                'town'                  => trim($validate->town),
                'visit_price'           => trim($validate->visit),
                'consultant_account'    => trim($validate->account),
                'grade'                 => trim($validate->grade),
                'tel'                   => trim($validate->tel),
                'mobile'                => trim($validate->mobile),
                'expert'                => trim($validate->expert),
                'password'              => ($validate->pass),

            ]);

像这样检查：

$update = DB::table('users')
            ->where('id',2)
            ->update
            ([
                'first_name'            => trim($validate->firstName),
                'capital'               => trim($validate->capital),
                'last_name'             => trim($validate->lastName),
                'town'                  => trim($validate->town),
                'visit_price'           => trim($validate->visit),
                'consultant_account'    => trim($validate->account),
                'grade'                 => trim($validate->grade),
                'tel'                   => trim($validate->tel),
                'mobile'                => trim($validate->mobile),
                'expert'                => trim($validate->expert),
                'password'              => ($validate->pass),

            ]);

if($update !== false){
//updated
}
else
{
//Not updated
}
