SQL查詢總數與單個值的比較

-1

我一直在與同級進行查詢，並且它已經開始回退一些不尋常的數字。查詢是一個生產力報告。我試圖將特定最終用戶的所有可結算單位總和，並將其與單個預期值進行比較，然後計算1個星期內這兩個數字之間的差異。下面是我們已經想出迄今：SQL查詢總數與單個值的比較

SELECT 
Employees.emp_id, 
Employees.last_name+', '+Employees.first_name as staff_name, 
SUM(VisitQuery.billed_value)/60 AS billed_value, 
SUM(StandardQuery.num8) as expected_value 
FROM 
Employees 
INNER JOIN 
(
    SELECT 
    ClientVisit.duration AS billed_value, 
    ClientVisit.emp_id, 
    ClientVisit.client_id 
    FROM 
    ClientVisit 
    WHERE 
    ClientVisit.non_billable = 0 AND 
    ClientVisit.rev_timeout >= @param1 AND 
    ClientVisit.rev_timeout <= @param2 
) VisitQuery 
ON VisitQuery.emp_id = Employees.emp_id 
INNER JOIN 
(
SELECT DISTINCT 
    CaseloadQuery.emp_id, 
    ClientsExt.num8 
FROM 
(
    SELECT 
    ClientVisit.duration AS billed_value, 
    ClientVisit.emp_id, 
    ClientVisit.client_id 
    FROM 
    ClientVisit 
    WHERE 
    ClientVisit.non_billable = 0 AND 
    ClientVisit.rev_timeout >= @param1 AND 
    ClientVisit.rev_timeout <= @param2 
) CaseloadQuery 
INNER JOIN ClientsExt 
ON CaseloadQuery.client_id = ClientsExt.client_id 
) StandardQuery 
ON Employees.emp_id = StandardQuery.emp_id 
GROUP BY 
Employees.emp_id, 
Employees.last_name+', '+Employees.first_name`enter code here`

返回找出來是這樣的：

emp_id  staff_name  billed_value expected_value 
X   X    74    231 
XX   XX    108    279 
XXX   XXX    19    72

沒有人有什麼想法？本週的預期值應該不會高於40小時。

你能提供的類/域圖？這將是真正有幫助的，歡呼 – Tatranskymedved

我很抱歉，但我相對較新的SQL，所以我不完全確定你在問我要什麼。 –

在ClientVisit表中，同一個員工（'emp_id'）可以有多行，導致多個'client_id'的值？ – leeyuiwah

在表ClientVisit中，同一位員工（emp_id）是否有多行可導致client_id的多個值？如果答案是肯定的，那麼我認爲你也應該做一個GROUP BYclient_id

下面我試着重寫你的查詢（注意標有「添加」和「刪除」的行）。

免責聲明：我沒有實際的數據庫表來測試我的查詢，所以它可能具有的語法和語義錯誤
