使用必須平衡

我目前正在編寫一個SQL語句，它要求我列出工作時間超過平均值的工作人員。這裏是我當前的代碼：使用必須平衡

Select T.TotalCandy,Sum(T.Amountofcandy) "Total Candy" 
From ToralChocolate 
Inner Join Ompaloompa O 
On T.CandyNo = O.CandyNo and T.BoatNO = O.BoatNo 
Inner Join Transport TR 
On TR.Transport = T.Transport 
Having Sum(T.AmountofCandy) > (Select Avg(AmountofCandy) from TotalChocolate) 
Group By T.TotalCandy 
Order By 1;

我在有聲明的子查詢碰到我的問題，因爲我比較它的平均工作時間不是工作小時數的總和的平均值！

任何幫助，將不勝感激。

Select W.WrkName,Sum(TI.HrsWorked) "Total Hours" 
From Timelog TI 
Inner Join Allocation A 
On TI.WrkID = A.WrkID and TI.TaskID = A.TaskID 
Inner Join Worker W 
On TI.WrkID = W.WrkID 
Group By W.WrkName 
Having Sum(TI.HrsWorked) > 
    (Select Avg(HrsWorked) 
    From 
     (Select WrkID, SUM(HrsWorked) As HrsWorked 
     From Timelog 
     Group By WrkID) 
    ) 
Order By 1;

你試過類似的東西嗎？

是的，這是完美的，我試過一個嵌套的子查詢之前，必須有一個語法錯誤，因爲它沒有工作，所以我認爲他們不可能-_-。非常感謝！ – Kaleon

歡迎您！ :) – Guneli

Select W.WrkName,Sum(TI.HrsWorked) "Total Hours" 
From Timelog TI 
Inner Join Allocation A 
On TI.WrkID = A.WrkID and TI.TaskID = A.TaskID 
Inner Join Worker W 
On TI.WrkID = W.WrkID 
Group By W.WrkName 
Having Sum(TI.HrsWorked) > (Select Avg(HrsWorked) from Timelog) 
Order By 1;

在組後有條款！
