Question

我在基于webSQL的Chrome扩展程序中有两个表：

第一张表：

@extends('layouts.app')

@section('content')
    <!-- header logo: style can be found in header.less -->
    <header class="header">
        <div class="container">
            <div class="row">
                <div class="col-lg-6">
                <a href="index.php" class="logo">
                    <!-- Add the class icon to your logo image or logo icon to add the margining -->
                    <img src="img/airbus-logo.png" />
                </a></div>
                <!-- Header Navbar: style can be found in header.less -->
                <div class="col-lg-6">
                    @include('partials._userModal')
                    @include('partials._menu')
                </div>
            </div>
        </div>
    </header>
    <div class="wrapper">
        <div class="container">
            <!-- Right side column. Contains the navbar and content of the page -->
            <aside class="content files-list clearfix">
                <h2>
                @if(Auth::check())
                Welcome {{ Auth::user()->fullName }}
                @endif
                </h2>
                    <div class="col-xs-5">
                        <h4>Change password</h4><br />
                        @if($errors->any())
                            @foreach($errors->all() as $error)
                                <p style='padding:15px;' class='bg-danger'>{{ $error }}</p>
                            @endforeach
                        @endif
                        @if(Request::get('errorMessage') !== null)
                            <p style='padding:15px;' class='bg-danger'>{{ Request::get('errorMessage') }}</p>
                        @endif
                        <form method="post">
                            {{ csrf_field() }}
                           <div class="placeholder">Current Password</div>
                            <input style="max-width:200px;" placeholder='Current password' name="oldpass" id="oldpass"  class="form-control" type="password"><br>
                            <div class="placeholder">New password</div>
                            <input style="max-width:200px;" placeholder='New password' name="password" id="password"  class="form-control" type="password"><br>
                            <div class="placeholder">Confirm password</div>
                            <input id="password_confirmation" style="max-width:200px;" placeholder='Confirm password' name="password_confirmation"  class="form-control" type="password">
                            <hr>
                            <input type="submit" class="btn btn-primary" value="Save">
                        </form>    
                    </div>
            </aside>
            <!-- /.right-side -->
        </div>
        <div style="  height: 155px;"></div>
        <div id="footer">
            <div class="container"> © Airbus Group 2015 </div>
        </div>
    </div>
    <!-- ./wrapper -->
    <!-- <script src="js/hub/demo.js" type="text/javascript"></script> -->
<script type="text/javascript">
    $(document).ready(function(){
        var bHeight = $("body").height();
        var wHeight = $( window ).height();
        if(bHeight < wHeight){
            $("#footer").addClass("absolute");
        }else{
            $("#footer").removeClass("absolute");
        }
        if (!$.support.htmlSerialize && !$.support.opacity){
            $(".placeholder").show();
        }
    });
</script>
@endsection

第二张表：

public function postChangePassword(Request $request)
    {
        $validatedData = $request->validate([
            'oldpass' => 'required|min:6',
            'password' => 'required|string|min:6',
            'password_confirmation' => 'required|same:password',
        ],[
            'oldpass.required' => 'Old password is required',
            'oldpass.min' => 'Old password needs to have at least 6 characters',
            'password.required' => 'Password is required',
            'password.min' => 'Password needs to have at least 6 characters',
            'password_confirmation.required' => 'Passwords do not match'
        ]);

        $current_password = \Auth::User()->password;           
        if(\Hash::check($request->input('oldpass'), $current_password))
        {          
          $user_id = \Auth::User()->id;                       
          $obj_user = User::find($user_id);
          $obj_user->password = \Hash::make($request->input('password'));
          $obj_user->save(); 
          return view('auth.passwords.changeConfirmation');
        }
        else
        {           
          $data['errorMessage'] = 'Please enter correct current password';
          return redirect()->route('user.getChangePassword', $data);
        }  
    }

第一张表中的每个条目都是一个村庄。 ID的值是唯一的并且对应于同一个村庄，因此每个村庄也有一个区域，但这些表格不能（轻松）创建为一个表格，所以我已经使用了：

CREATE TABLE table1 (ID int, X int, Y int, tID int, vID int, Village varchar(50), 
uID int, Player varchar(50), aID int, Alliance varchar(20), Population int)

我想获得每个区域中每个联盟的总和，因此结果类似于：

CREATE TABLE table2 (ID int, Region varchar(20))

......等等。

Answer 1

试试这个

select b.region, a.alliance, sum(a.population) from
table1 a join table2 b on a.aid=b.id group by b.region, a.alliance;
