在两列中合并两个sql查询的结果

Question

查询1:

SELECT COUNT (A.EMPNO) AS [PRESENT]    
FROM ERPDATA.NIITESS.DBO.ZEMP_MASXST_WEB_AL A INNER                    
JOIN PPA_EVENTWISEEMPLOYEEMASTER B ON 
(CASE B.VC_BA WHEN '%' THEN LTRIM(RTRIM(A.PDIBUSHORT)) ELSE B.VC_BA END) =  LTRIM(RTRIM(A.PDIBUSHORT))                   
AND (CASE B.VC_PA WHEN '%' THEN A.PA ELSE B.VC_PA END) = A.PA                
WHERE A.STATUS = 3  
AND A.EMPNO IN (SELECT VC_EMPCODE FROM ERPDATA.NIITESS.DBO.ADA_MXEASTER WHERE IN_ATTENDANCE_STATUS = 1 AND CH_ACTIVE = 'Y' AND VC_EMPCODE <> '')                    
GROUP BY B.IN_EVENTID

查询2:

SELECT COUNT (A.EMPNO) AS [TOTAL]    
FROM ERPDATA.NIITESS.DBO.ZEMP_MASXST_WEB_AL A INNER                    
JOIN PPA_EVENTWISEEMPLOYEEMASTER B ON 
(CASE B.VC_BA WHEN '%' THEN LTRIM(RTRIM(A.PDIBUSHORT)) ELSE B.VC_BA END) =  LTRIM(RTRIM(A.PDIBUSHORT))                   
AND (CASE B.VC_PA WHEN '%' THEN A.PA ELSE B.VC_PA END) = A.PA                
WHERE A.STATUS = 3  

我想将两个结果合并为两列,其中缺少列=查询2 - 查询1以更快地处理速度.我该怎么做？示例:
我有两个结果:
// ---------------------------------------- QUERY :1
1
2
3
4
// -------------------------------------- QUERY:2
4
5
6
8

// ------------------------------------结果如同两列
1 5
2 6
3 7
4 8

Answer 1

Select a.C1-b.C2 as Res
 from
(
Select Count(*) as C1 from Users
Group by Name
) a
join
(
Select Count(*) as C2 from User2
Group by Name
) b ON 1=1 -- or desired condition if existing
