sql - 使用 GROUP BY 对两个 SELECT COUNT 查询求和

Question

我在链接数据库中有两个查询（链接来自两个不同项目数据库的表）。我需要组合查询以获得按 Interaction_Type1 分组的总计数。SQL代码如下：

查询#1：

SELECT Sum(Temp.cnt) AS SumOfcnt, Temp.Interaction_Type1
FROM (SELECT COUNT(*) as cnt, Interaction_Type1 from AMERILOCKMasterConversionTable 
GROUP BY Interaction_Type1

UNION ALL

SELECT COUNT(*), Interaction_Type2 from AMERILOCKMasterConversionTable
GROUP BY Interaction_Type2

UNION ALL

SELECT COUNT(*), Interaction_Type3 from AMERILOCKMasterConversionTable
GROUP BY Interaction_Type3
)  AS Temp
GROUP BY Temp.Interaction_Type1;

和查询#2

SELECT Sum(Temp.cnt) AS SumOfcnt, Temp.Interaction_Type1
FROM (SELECT COUNT(*) as cnt, Interaction_Type1 from MARKETMasterConversionTable 
GROUP BY Interaction_Type1

UNION ALL

SELECT COUNT(*), Interaction_Type2 from MARKETMasterConversionTable 
GROUP BY Interaction_Type2

UNION ALL

SELECT COUNT(*), Interaction_Type3 from MARKETMasterConversionTable 
GROUP BY Interaction_Type3
)  AS Temp
GROUP BY Temp.Interaction_Type1;

我希望查询产生以下结果：

Interaction_Type1          Total
Left_Message                23
Made_Contact                16
Bad_Phone_Number             8
No_Answer                   12

我是 SQL 的新手，并且已经在线研究了所有这些，并且没有运气将这两个查询结合起来产生所需的结果。

任何帮助将不胜感激！！

谢谢！红色的

你应该有类似的东西

SELECT  Integration_Type, SUM(*)
FROM    (  SELECT Integration_Type, SumOfcnt FROM VIEW1
           UNION ALL
           SELECT Integration_Type, SumOfcnt FROM VIEW2)
GROUP BY Integration_Type

但在为您在此处提供的查询创建视图之前，或者只是在单个视图中收集所有查询。
