如何使用聯合來顯示捲起的值

Question

我正在使用DB2語法並希望使用UNION來創建額外的行以顯示捲起的值。

而不是這樣做，工會的第一部分只是命名列，而來自第二個工會的數據出現。

這裏是第一部分

SELECT 'DRIVER ID' AS DRIVER_ID, 'NAME' AS NAME, 'PUNIT' AS PUNIT, 'PHONE' AS PHONE, 1767 AS TERMINAL_NUMBER, 'DRIVER TYPE' AS DRIVER_TYPE, 
COALESCE((SELECT ROUND(DEC(SUM(CASE WHEN UPDATED_BY IN ('VISTAR','TM4WIN') THEN 1.00 ELSE 0.00 END))/COUNT(UPDATED_BY),2) FROM ODRSTAT, TLORDER L, DRIVER D WHERE DETAIL_LINE_ID = ORDER_ID AND STATUS_CODE IN ('ARRV@SHIP', 'ARRV@CONS', 'DEPT@SHIP', 'DEPT@CONS') 
AND CURRENT_STATUS IN ('EDIBILLED','BILLD') AND L.PICK_UP_DRIVER = D.DRIVER_ID AND 
D.TERMINAL_NUMBER IN (SELECT UNIQUE FIRST_FIELD_INSERT FROM SITE WHERE FAX_PHONE_NUMBER = :DIVISION) AND BILL_DATE BETWEEN CURRENT DATE - 1 MONTH AND CURRENT DATE AND ACTUAL_DELIVERY > ACTUAL_PICKUP +30 SECONDS),0) AVG_STATUS_UPDATE, 
ROUND(((SELECT MAX(ODOMETER)-MIN(ODOMETER) FROM ODOHIST O 
WHERE READINGDATE >= CURRENT DATE - 30 DAYS AND O.UNIT_ID IN (SELECT UNIT_ID FROM PUNIT WHERE ACTIVE_WHERE = 'D' AND FLEET_ID IN (SELECT UNIQUE USER5 FROM SITE WHERE FAX_PHONE_NUMBER = :DIVISION))) 
/(SELECT NULLIF(SUM(T2.VOL_PFUEL),0) FROM FC_POS T2 INNER JOIN DRIVER D ON T2.DRIVER_ID = D.DRIVER_ID 
WHERE D.TERMINAL_NUMBER IN (SELECT UNIQUE FIRST_FIELD_INSERT FROM SITE WHERE FAX_PHONE_NUMBER = :DIVISION) AND POS_DATE >= CURRENT DATE - 30 DAYS)),2) AVG_MPG, 
(SELECT ROUND(AVG(TIMES),2) FROM (SELECT DELIVERY_DRIVER, ROUND(AVG(DEC((DAYS(CHECKIN_DATE) - DAYS(ACTUAL_DELIVERY)) *24 + (HOUR(CHECKIN_DATE) - HOUR(ACTUAL_DELIVERY)))/24),2) TIMES

UNION ALL

我沒有看過你的代碼......由於缺乏格式化的，它不容易。

但是，當我在過去使用UNION提供捲起的值時，我已經包含了額外的列，爲我提供了區分細節和總計的方法。這些額外的列也被用來作爲第一列ORDER BY

例子：

select      
    digits(HCUSNR) as Cust_Num, 
    CCUSNM, 
    char(HINVNR), 
    hinamt, 
-- Control fields     
    ' ' concat digits(HCMPCL),  
    case        
    when HTRCDE in ('A', 'E', 'R') 
     then ' LVL3'    
    else ' LVL1'     
    end,        
    HCUSNR, DDVDSC, HDIVSN   
UNION ALL 

select  
    ' ', 
    'Daily Invoice Total', 
    ' ', 
    sum(hinamt), 
-- Control Fields          
    ' ' concat digits(HCMPCL), ' LVL2', 0, ' ', HDIVSN 
group by    
    HDIVSN, HCMPCL 
--Following order by applies to entire results set 
order by 5,6,7,8,9 

但上面是近20年前寫的...

如果我現在需要做的，我將使用IBM添加到數據庫的分組集，彙總和多維數據集功能。

您使用的是哪個平臺和DB2版本？分組集合，彙總和/或多維數據集是一個選項嗎？
