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,其中缺少一列=查询2-查询1以加快处理速度。我该怎么做?示例: 我有两个结果: // ----------------------------------------查询:1 1 2 3 4 // --------------------------------------查询:2 4 5 6 8
// ------------------------------------两列结果AS 1 5 2听6 3听7 4听8
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
