SQL：更改 SELECT 查询以根据 B 列中的布尔值在 A 列上显示不同的值

Question

我有一个生成此输出的 SQL 查询：

如果“CROSSDOMAIN”列的值为 true?，我将如何调整我的查询以使“SCORE”列的值增加 3 我在想我会用另一个处理这种情况的查询来包装我现有的查询，但我不确定那个查询是什么。

我现有的查询如下（不是最漂亮的，但有效）：

                SELECT HORSUM.TEAMNAME, HORSUM.EMAIL1, SUM(HORSUM.TOTALSUM) Score, COUNT(*) Count, TEAM.THEME, TEAM.FINALIST, TEAM.WINNER, TEAM.CROSSDOMAIN
                FROM 
                    (SELECT "JUDGEEMAIL", "TEAMNAME", "EMAIL1", "DEVOPSPRACTICES" + "BUSINESSIMPACT" + 
                    "NEWSKILLS" + "EXECUTION"
                    + "INNOVATION" + "CLARITY" as totalSum
                    FROM "DOMAINSCORES") AS HORSUM
                INNER JOIN (SELECT "THEME", "TEAMNAME" as nameID, "FINALIST", "WINNER", "CROSSDOMAIN" FROM "TEAMS" WHERE "FINALIST" = True) AS TEAM ON HORSUM.TEAMNAME = TEAM.nameID
                GROUP BY "TEAMNAME", EMAIL1, THEME, FINALIST, WINNER, CROSSDOMAIN
                ORDER BY Score DESC;

编辑：我已经按照 Michael 的建议尝试了这个查询，但出现语法错误。我还想补充一点，我使用的是 IBM 的 DB2，如果这有所不同的话。

SELECT HORSUM.TEAMNAME
     , HORSUM.EMAIL1
     , case
         when TEAM.CROSSDOMAIN = 'true' 
         then SUM(HORSUM.TOTALSUM) + 3
         else SUM(HORSUM.TOTALSUM) 
       end as Score
     , COUNT(*) Count
     , TEAM.THEME
     , TEAM.FINALIST
     , TEAM.WINNER
     , TEAM.CROSSDOMAIN
FROM
(SELECT HORSUM.TEAMNAME, HORSUM.EMAIL1, SUM(HORSUM.TOTALSUM) Score, COUNT(*) Count, TEAM.THEME, TEAM.FINALIST, TEAM.WINNER, TEAM.CROSSDOMAIN
                FROM 
                    (SELECT "JUDGEEMAIL", "TEAMNAME", "EMAIL1", "DEVOPSPRACTICES" + "BUSINESSIMPACT" + 
                    "NEWSKILLS" + "EXECUTION"
                    + "INNOVATION" + "CLARITY" as totalSum
                    FROM "DOMAINSCORES") AS HORSUM
                INNER JOIN (SELECT "THEME", "TEAMNAME" as nameID, "FINALIST", "WINNER", "CROSSDOMAIN" FROM "TEAMS" WHERE "FINALIST" = True) AS TEAM ON HORSUM.TEAMNAME = TEAM.nameID
                GROUP BY "TEAMNAME", EMAIL1, THEME, FINALIST, WINNER, CROSSDOMAIN)
ORDER BY Score DESC;

Answer 1

试试这个作为外部 SELECT

SELECT HORSUM.TEAMNAME
     , HORSUM.EMAIL1
     , case
         when TEAM.CROSSDOMAIN = 'true' 
         then SUM(HORSUM.TOTALSUM) + 3
         else SUM(HORSUM.TOTALSUM) 
       end as Score
     , COUNT(*) Count
     , TEAM.THEME
     , TEAM.FINALIST
     , TEAM.WINNER
     , TEAM.CROSSDOMAIN
     ...
