mysql - 我的 sql 查询根据多个条件对列值求和

Question

查询表结果

 SELECT cc.Contact_ID
      , SUM(HeadCount)
      , c.ClientID
      , c.Client_Name 
      , cc.Contact_Name
      , cc.Role
      , cs.Communication
      , cs.ResponseTime
      , cs.LeadershipStyle
      , cs.Trust
      , cs.Sentiment
   FROM client c 
   LEFT 
   JOIN client_contact cc 
     ON c.ClientID = cc.Client_ID 
   JOIN process p 
     ON c.ClientID = p.ClientID 
    AND cc.Contact_Process = p.ProcessID
   JOIN verticals v 
     ON v.VerticalID = cc.Contact_Vertical
   LEFT 
   JOIN client_sentimental_indicator cs 
     ON cs.ClientContactID = cc.Contact_ID
  WHERE c.STATUS = 1 
    AND p.ProcessStatus = 0
    AND cc.status = 0   
  GROUP 
     BY c.ClientID
      , cc.Contact_ID
  ORDER 
     BY c.client_Name

这是表格结果

ID  Sum(headcount) CID     CName        contname
339   6            340      xxx         Inc Andy Stetson        
340   3            340      xxx         Danielle du Toit        
351   3            322      yyy         Ron Mahulkar        
350   3            322      zzz         Nicholas Ho     
349   3             322     zzz         Will Power      
271   74            102     vvv         Carie Hinton        
338   31            102     vvv         Linda Dunn      
283   9             102     vvv         Waseem Khan 

我需要如下结果

ID  Sum(headcount) exactSum CID    CName        contname
339   6            9        340     xxx         Inc Andy Stetson        
340   3                     340     xxx         Danielle du Toit        
351   3            3        322     yyy         Ron Mahulkar        
350   3                     322     zzz         Nicholas Ho     
349   3                     322     zzz         Will Power      
271   74           114      102     vvv         Carie Hinton        
338   31                    102     vvv         Linda Dunn      
283   9                     102     vvv         Waseem Khan 

我有CID重复，需要重复显示，需要根据CID求和

请大家帮忙
