如何求和兩個不同的 SQL 查詢的結果？

Question

我想對這兩個不同的查詢求和。 我加入了 USING function。但它在兩個不同的單元格中顯示了兩個結果。

我需要一個結果來對這兩個查詢求和，答案應該是 4069。

代碼

SELECT COUNT(*) Active_Projects FROM
(SELECT ProjectID, ProjectStatusID, ClientID
FROM project) a
INNER JOIN 
(SELECT ProjectStatusID, ClientID, ProjectStatusName
FROM ProjectStatus) b
ON (a.ProjectStatusID = b.ProjectStatusID AND a.ClientID = b.ClientID)
WHERE ProjectStatusName LIKE '%active%'
AND a.ClientID = 4

UNION

SELECT COUNT(*) Total_Projects
FROM Project
WHERE ClientID=4

嘗試這個。 select query1+ query2;

select (
    SELECT COUNT(*) Active_Projects FROM
(SELECT ProjectID, ProjectStatusID, ClientID
FROM project) a
INNER JOIN 
(SELECT ProjectStatusID, ClientID, ProjectStatusName
FROM ProjectStatus) b
ON (a.ProjectStatusID = b.ProjectStatusID AND a.ClientID = b.ClientID)
WHERE ProjectStatusName LIKE '%active%'
AND a.ClientID = 4
) + (
SELECT COUNT(*) Total_Projects
FROM Project
WHERE ClientID=4) ;
