總計函數/分組條款

對我的查詢有一些小問題。我正在努力爲項目獲得款項。我知道我可能錯過了一些超級簡單的東西，但我陷入了困境。如果有人可以看看，並給我一個關於如何解決這個問題的建議。總計函數/分組條款

select 
    (select count(distinct(o1.orderno)) 
     from mck_hvs.orderheader o1 with(nolock) 
     where o1.orderno = od.orderno and o1.refrigerate = 'Y' 
     ) as TotalColdOrders,

一個LEFT JOIN ON ORDERHEADER和ORDERDETAILS並在SELECT超過GROUP申請案件或IIF BY – maSTAShuFu

你有什麼問題？錯誤的結果或SQL錯誤？預期的結果或錯誤信息是什麼？ –

我得到「消息8120，級別16，狀態1，行1列'Mck_hvs.orderdetails.orderno」在選擇列表中無效，因爲它不包含在聚合函數或GROUP BY子句中。 –

你應該試試這個：

SELECT 
    od.orderno, 
    COUNT(DISTINCT 
     CASE WHEN oh.refrigerate = 'Y' THEN od.orderno END 
    ) AS totalcoldorders, 
    COUNT(DISTINCT 
     CASE WHEN od.drugclass NOT IN ('null', 'Rx') THEN od.orderno END 
    ) AS controlledorders, 
    COUNT(DISTINCT 
     CASE 
      WHEN oh.pucksideinorder = 'Y' 
       AND oh.totesideinorder = 'N' AND oh.numitems > 4 
      THEN od.orderno 
     END 
    ) AS robotorders, 
    COUNT(DISTINCT 
     CASE 
      WHEN oh.pucksideinorder = 'Y' AND oh.totesideinorder = 'Y' 
      THEN oh.orderno 
     END 
    ) AS comboorders, 
    COUNT(DISTINCT 
     CASE WHEN od.refrigerate = 'Y' THEN od.rxnum END 
    ) AS totalcoldscripts, 
    COUNT(DISTINCT 
     CASE WHEN od.drugclass NOT IN ('null', 'RX') THEN od.rxnum END 
    ) AS controlledscripts, 
    SUM(
     CASE 
      WHEN oh.pucksideinorder = 'Y' 
       AND oh.totesideinorder = 'N' AND oh.numitems > 4 
      THEN oh.numscripts 
     END 
    ) AS robotscripts, 
    SUM(
     CASE 
      WHEN oh.pucksideinorder = 'Y' AND oh.totesideinorder = 'Y' 
      THEN oh.numscripts 
     END 
    ) AS comboorderscripts, 
    (
     SELECT COUNT(DISTINCT orderno) 
     FROM mck_hvs.orderdetails WITH (nolock) 
    ) AS totalorders, 
    (
     SELECT COUNT(DISTINCT rxnum) 
     FROM mck_hvs.orderdetails WITH (nolock) 
    ) AS totalscripts 
FROM mck_hvs.orderdetails od WITH (nolock) 
LEFT JOIN mck_hvs.orderheader oh WITH (nolock) 
ON oh.orderno = od.orderno 
GROUP BY od.orderno 
ORDER BY od.orderno;
