Question

我想得到第3栏和第3栏的总分数。列1和1中的每个县都有4个如下表所示2：

County1    |    County2     |   Player1_Score   |   Player2_Score
Norfolk    |    Hampshire   |       5           |       7
Suffolk    |    Norfolk     |       10          |       6
Hampshire  |    Suffolk     |       16          |       12
Norfolk    |    Suffolk     |       78          |       50
Hampshire  |    Norfolk     |       4           |       8
Suffolk    |    Hampshire   |       9           |       19

所以我希望看到的结果如下：

Norfolk     |       97
Suffolk     |       77
Hampshire   |       32

任何人都可以帮忙吗？我尝试了一个SELECT/GROUP BY查询但对SQL很新，无法获得我想要的结果。

非常感谢

试试这个：

**This is ajax function**

  $.ajax({  
     type : "Get",   
     url : url, 
     data:$("#client").serialize(),
     dataType:'json',
     success : function(response) 
     {  

     },  
     error : function(e) 
     {  
      alert('Error: ' + e); 

     }  
    });
