變化從SQL到SQL-CE - 語法

Question

我已經要求下面的代碼問題： Here is the question.

我有我在我的數據庫查詢（SQL Server）的使用下面的SQL語法。

MERGE INTO table_with_team_and_goals AS target 
USING (SELECT Team, SUM(headergoal + freekickgoal) AS goals FROM table_with_goals GROUP BY team) AS source 
ON target.team=source.team 
WHEN MATCHED THEN 
     UPDATE SET goals = source.goals 
    WHEN NOT MATCHED THEN 
     INSERT (Team, Goals) 
     VALUES (source.team, source.goals); 

我正在改變到sql-server-ce（精簡版）。 我可以發現，SQL Server Compact不支持sql支持的一些命令。 （如marge into）

如何更改代碼，使其可以在SQL Server Compact上運行。

謝謝你的幫助！ BK

編輯：

表：table_player_goal_ratings - >包含以下數據：

ID......Team...........Name......HeaderGoal......FreeKickGoal 
104  Barcelona  Mike  2    1 
105  Barcelona  Peter  0    0 
106  Real Madrid Michael 0    2 
107  Real Madrid Terry  0    2 
108  Chelsea  James  0    0 
109  Chelsea  Arthur 1    2 
110  Chelsea  Spence 1    2 

現在我想在下面的表格（table_team_goal_ratings）插入這些數據是這樣：

FC.............Goals 
Barcelona  3 
Real Madrid 4 
Chelsea  6 

Answer 1

您可以使用UPDATE和INSERT：

BEGIN TRANSACTION; 

UPDATE A 
SET goals = B.goals 
FROM dbo.table_with_team_and_goals A 
INNER JOIN (SELECT team, SUM(headergoal + freekickgoal) AS goals 
      FROM table_with_goals 
      GROUP BY team) B 
    ON A.team = B.team 

INSERT INTO dbo.table_with_team_and_goals(team, goals) 
SELECT team, goals 
FROM ( SELECT team, SUM(headergoal + freekickgoal) AS goals 
     FROM table_with_goals 
     GROUP BY team) A 
WHERE NOT EXISTS(SELECT 1 FROM dbo.table_with_team_and_goals 
       WHERE team = A.team) 

COMMIT TRANSACTION;
