如何通過條款

Question

查詢申請組

SELECT 
    TIMECARD.EMP_ID, TIMECARD.TIMECARD_ID, TIMECARD.TIMECARD_STATUS, 
    TASK.MAN_HOURS 
FROM 
    TRN_TIMECARD_ACTIVITY ACT 
INNER JOIN 
    TRN_TIMECARD TIMECARD ON TIMECARD.TIMECARD_ID = ACT.TIMECARD_ID 
INNER JOIN 
    TRN_TIMECARD_TASK TASK ON TASK.TIMECARD_ID = TIMECARD.TIMECARD_ID 
WHERE 
    ACT.TIMECARD_STATUS IN ('AP','RE') 

OUTPUT：

61 42 AP 9 
61 42 AP 9 
61 43 AP 9 
61 43 AP 9 
61 47 AP 7 

我有emp_id獲得組和計算sum(man_hours)。

如何獲得像下面

61 42 AP 52 

Answer 1

值......看不出中間的兩列在你的組如何計算的，所以我會做：

SELECT  TIMECARD.EMP_ID, SUM(TASK.MAN_HOURS) 
FROM   TRN_TIMECARD_ACTIVITY ACT 
INNER JOIN TRN_TIMECARD TIMECARD ON TIMECARD.TIMECARD_ID=ACT.TIMECARD_ID 
INNER JOIN TRN_TIMECARD_TASK TASK ON TASK.TIMECARD_ID=TIMECARD.TIMECARD_ID 
WHERE   ACT.TIMECARD_STATUS IN('AP','RE') 
GROUP BY  TIMECARD.EMP_ID 

Answer 2

根據您的期望的結果，我看到你給列TIMECARD.TIMECARD_ID的TASK.MAN_HOURS的Minimum（最低）值和Sum（總）。 （但我爲什麼你的52價值沒有得到）

SELECT TIMECARD.EMP_ID, 
     MIN(TIMECARD.TIMECARD_ID) time_card, 
     TIMECARD.TIMECARD_STATUS, 
     SUM(TASK.MAN_HOURS) totalHours 
FROM TRN_TIMECARD_ACTIVITY ACT 
     INNER JOIN TRN_TIMECARD TIMECARD ON TIMECARD.TIMECARD_ID=ACT.TIMECARD_ID 
     INNER JOIN TRN_TIMECARD_TASK TASK ON TASK.TIMECARD_ID=TIMECARD.TIMECARD_ID 
WHERE ACT.TIMECARD_STATUS IN('AP','RE') 
GROUP BY TIMECARD.EMP_ID, TIMECARD.TIMECARD_STATUS 

Answer 3

我認爲這將有助於你... TIMECARD.TIMECARD_ID

取最低

SELECT TIMECARD.EMP_ID, 
     MIN(TIMECARD.TIMECARD_ID) TIMECARD_ID, 
     TIMECARD.TIMECARD_STATUS, 
     SUM(TASK.MAN_HOURS) HOURS 
FROM TRN_TIMECARD_ACTIVITY ACT 
INNER JOIN 
TRN_TIMECARD TIMECARD ON TIMECARD.TIMECARD_ID=ACT.TIMECARD_ID 
INNER JOIN 
TRN_TIMECARD_TASK TASK ON TASK.TIMECARD_ID=TIMECARD.TIMECARD_ID 
WHERE ACT.TIMECARD_STATUS IN('AP','RE') 
GROUP BY TIMECARD.EMP_ID,TIMECARD.TIMECARD_STATUS
