sql - 选择时和总和

Question

我有表匹配，我需要目标总和。如果Match.Home_team='Tupesy'我需要总和，Match.Home_team='Tupesy'否则sum。Match.Away_goals

现在我有了这个，但完全错误：/

SELECT *,
    CASE (Match.Home_team)
        WHEN (Match.Home_team='Tupesy')THEN (SUM(Match.Home_goals))
        ELSE (SUM(Match.Away_goals))
        END
FROM Match
Where (Match.ID_match='1');

Answer 1

可能是这样（SUM 和 CASE 应该以相反的顺序编写）：

select Sum(case
             when (Home_Team = 'Tupesy') then
               Home_goals
             else 
               Away_goals 
           end)
  from Match
 where (ID_match = '1')
