laravel常用查询

插入

DB::table('t_admin_users')->insert([
    [
        'role_id'    => $allData['roleId'],
        'username'   => $allData['userName'],
        'real_name'  => $allData['realName'],
        'avatar'     => "",
        'created_at' => date("Y-m-d H:i:s", time()),
        'group_id'   => $adminUser->group_id,
        'password'   => md5(getRandString(10))
    ]
]);

删除

DB::table('t_admin_users')->where('id', $allData['toUserId'])->delete();

只取某个值

 $day = DB::table('t_backend_user_disable_record')->where('user_id', $user->user_id)->value('day');

联查

 $user = DB::connection('appsql')->table('k_users')
      ->leftJoin("k_user_wallet", "k_user_wallet.user_id", "=", "k_users.id")
      ->leftJoin("k_user_infos", "k_user_infos.user_id", "=", "k_users.id")
      ->leftJoin("kl_admin.t_backend_user_disable_record", "kl_admin.t_backend_user_disable_record.user_id", "=", "k_users.id")
      ->select("*", "k_users.status as banned_status", "k_users.id as user_id")
      ->where('k_users.id', $allData['toUserId'])->first();

更新

DB::connection('appsql')->table('k_users')
      ->where('id', $toUserId)
      ->update(['invite_type' => $inviteType]);

自定义count和sum

$logs = DB::connection('appsql')->table('k_user_infos')
      ->leftJoin('k_user_wallet', 'k_user_infos.user_id', '=', 'k_user_wallet.user_id')
      ->leftJoin('k_users', 'k_users.id', '=', 'k_user_infos.user_id')
      ->select(
          DB::raw("COUNT(k_user_infos.`device_name`= 'ios' or null) as total_ios"),
          DB::raw("COUNT(k_user_infos.`device_name`= 'aos' or null) as total_aos"),
          DB::raw("COUNT(k_user_infos.`device_name`= 'ios' and k_user_wallet.`total_recharge` > 0 or null) as ios_recharge_num"),
          DB::raw("COUNT(k_user_infos.`device_name`= 'aos' and k_user_wallet.`total_recharge` > 0 or null) as aos_recharge_num"),
          DB::raw("sum(case when k_user_infos.`device_name`= 'ios' then k_user_wallet.`total_recharge` else 0 end) as ios_recharge_sum"),
          DB::raw("sum(case when k_user_infos.`device_name`= 'aos' then k_user_wallet.`total_recharge` else 0 end) as aos_recharge_sum"),
          DB::raw("COUNT(k_user_infos.`device_name`= 'ios' and k_users.`reg_time` > '{$date}' or null) as ios_today_num"),
          DB::raw("COUNT(k_user_infos.`device_name`= 'aos' and k_users.`reg_time` > '{$date}' or null) as aos_today_num"),
          DB::raw("COUNT(k_user_infos.`device_name`= 'ios' and k_users.`reg_time` > '{$date}' and k_user_wallet.`total_recharge` > 0 or null) as ios_today_recharge_num"),
          DB::raw("COUNT(k_user_infos.`device_name`= 'aos' and k_users.`reg_time` > '{$date}' and k_user_wallet.`total_recharge` > 0 or null) as aos_today_recharge_num")
      )
      ->get();

按类型查询

 //获取查询类型
function getTimeTye($type) {
    switch ($type) {
        case 1://小时
            $format = "DATE_FORMAT(time,'%Y-%m-%d-%H')";
            break;
        case 2://天
            $format = "DATE_FORMAT(time,'%Y-%m-%d')";
            break;
        case 3://周
            $format = "DATE_FORMAT(time,'%Y-%u')";
            break;
        case 4://月
            $format = "DATE_FORMAT(time,'%Y-%m')";
            break;
        case 5://分钟
            $format = "DATE_FORMAT(time,'%Y-%m-%d-%H-%i')";
            break;
    }
    return $format;
}

having 判断自定义字段

$users = DB::connection('appsql')->table('k_users')
       ->select("*", DB::raw("count(k_users.id) as num"))
       ->where("reg_ip", "<>", "unknown")
       ->where("reg_ip", "<>", "")
       ->where("reg_ip", "<>", "127.0.0.1")
       ->groupBy("reg_ip")
       ->having('num', '>', 3)
       ->limit(50)->get();
