Laravel连接两个表

Question

我有两个表，即看表，然后单击表像之下

id View_count Created_at 
1 10   January 
2 20   Febrauary 
3 30   March 

id Click_count Created_at 
1 20   January 
2 40   March 
3 30   May 

我想指望根据一个月的数据。通过查询，我想获得如下所示的表格信息。

Created_at View_count Click_count 
January   10   20 
Febrauary  20 
March   30   40 
May    30 

我试图为这样的：

$view_count= View::select(DB::raw("count(*) as count")) 
     ->orderBy("created_at") 
     ->groupBy(DB::raw("month(created_at)")) 
     ->get()->toArray(); 
    $view_count= array_column($view_count, 'count'); 

$click_count= Click::select(DB::raw("count(*) as count")) 
     ->orderBy("created_at") 
     ->groupBy(DB::raw("month(created_at)")) 
     ->get()->toArray(); 
    $click_count= array_column($click_count, 'count'); 


$count_bymonth = View::select(DB::raw('MONTHName(created_at) as month')) 
     ->groupBy(DB::raw(' MONTH(created_at)')) 
     ->get()->toArray(); 
    $count_bymonth = array_column($count_bymonth , 'month'); 


return view('testing') 
     ->with('view_count', json_encode($view_count, JSON_NUMERIC_CHECK)) 
     ->with('click_count', json_encode($click_count, JSON_NUMERIC_CHECK)) 
     ->with('count_bymonth', json_encode($count_bymonth, JSON_NUMERIC_CHECK)); 

如果有人知道这个答案请不要让我尽快知道。

谢谢。

Answer 1

你可以做，在一个查询

$result = View::join('Click','Click.Created_at','=','View.Created_at') 
      ->select(
      'Click_count.Created_at' 
      DB::raw('SUM(Click_count) as Click_count'), 
      DB::raw('SUM(View_count) as View_count') 
     ) 
      ->groupBy('Click.Created_at') 
      ->orderBy("created_at") 
      ->get(); 

return view('testing')->with('result'); 

然后，所有你需要做的是循环的result。

Answer 2

使用laravel查询生成器连接

DB::table('View') 
      ->join('Click', 'View.Created_at', '=', 'Click.Created_at')->get();
