獲取每個SQL行的總和

您好我已經寫了查詢下面的問題，我的問題是顯然返回整個表的總和（所有員工在一起），我希望它返回每個員工的總和，這完全有可能嗎？獲取每個SQL行的總和

DECLARE @temp TABLE 
(
TotalAmount DECIMAL, 
ExpenseCategory UNIQUEIDENTIFIER, 
EmployeeId UNIQUEIDENTIFIER, 
CategoryName NVARCHAR(100) 
) 

INSERT INTO @temp 

SELECT SUM(dbo.ExpenseDetails.TotalAmount) AS TotalAmount,   
dbo.ExpenseDetails.ExpenseCategory, dbo.ExpenseDetails.EmployeeId, 
dbo.ExpensesCategories.CategoryName 
FROM   dbo.ExpenseDetails INNER JOIN 
        dbo.ExpensesCategories ON 
dbo.ExpenseDetails.ExpenseCategory = dbo.ExpensesCategories.CategoryId 
WHERE  (CONVERT(DATE, dbo.ExpenseDetails.DateAdded) < CONVERT(DATE, 
DATEADD(m, DATEDIFF(m, 0, CONVERT(DATE, GETDATE())), 23 - 1))) AND 
(CONVERT(DATE, dbo.ExpenseDetails.DateAdded) > CONVERT(DATE, 
         DATEADD(MONTH, - 1, DATEADD(m, DATEDIFF(m, 0, 
CONVERT(DATE, GETDATE())), 23 - 1)))) 
GROUP BY dbo.ExpenseDetails.ExpenseCategory, dbo.ExpenseDetails.EmployeeId, 
dbo.ExpensesCategories.CategoryName 

SELECT 
EmployeeId, 
(SELECT SUM(TotalAmount) FROM @temp WHERE EmployeeId = [@temp].EmployeeId 
and ExpenseCategory = '6CC0F801-D295-4997-9D1F-3E5B2BE692ED') AS TotalFuel, 
(SELECT SUM(TotalAmount) FROM @temp WHERE EmployeeId = [@temp].EmployeeId 
and ExpenseCategory = '3E54C10B-ECBE-4B28-87A4-5A4E43AACDFC') AS TotalRail, 
(SELECT SUM(TotalAmount) FROM @temp WHERE EmployeeId = [@temp].EmployeeId 
and ExpenseCategory = '31CC43A4-80E6-4DD4-A28C-039F05AF62A3') AS 
TotalParking, 
(SELECT SUM(TotalAmount) FROM @temp WHERE EmployeeId = [@temp].EmployeeId 
and ExpenseCategory = '01250A30-3865-40D2-9E49-DA2B9898B1F4') AS 
TotalMileage, 
(SELECT SUM(TotalAmount) FROM @temp WHERE EmployeeId = [@temp].EmployeeId 
and ExpenseCategory = 'F4E4582D-DEDF-499D-BBC1-45003B865218') AS TotalEquip, 
(SELECT SUM(TotalAmount) FROM @temp WHERE EmployeeId = [@temp].EmployeeId 
and ExpenseCategory = '55F471C1-6E52-4898-8263-0B7684B78E7C') AS TotalPPS, 
(SELECT SUM(TotalAmount) FROM @temp WHERE EmployeeId = [@temp].EmployeeId 
and ExpenseCategory = '1EE0FC40-193F-4720-9143-0B61FFDE7B8D') AS TotalOther 

FROM @temp GROUP BY EmployeeId

使用SUM與條件：

SELECT 
    EmployeeId, 
    TotalFuel = SUM(CASE WHEN ExpenseCategory = '6CC0F801-D295-4997-9D1F-3E5B2BE692ED' THEN TotalAmount END) 
FROM @temp 
GROUP BY EmployeeId

米哈伊爾·你好，這工作得很好，唯一的問題是現在，它不會讓我組由僱員，所以我結束了重複行。 –

我錯過了。隨着'組'，你不需要'OVER' –

乾杯米哈伊爾，偉大的工程！ –

SELECT 
EmployeeId, 
(SELECT SUM(TotalAmount) FROM @temp WHERE ExpenseCategory = '6CC0F801-D295-4997-9D1F-3E5B2BE692ED') AS TotalFuel, 
(SELECT SUM(TotalAmount) FROM @temp WHERE ExpenseCategory = '3E54C10B-ECBE-4B28-87A4-5A4E43AACDFC') AS TotalRail, 
(SELECT SUM(TotalAmount) FROM @temp WHERE ExpenseCategory = '31CC43A4-80E6-4DD4-A28C-039F05AF62A3') AS TotalParking, 
(SELECT SUM(TotalAmount) FROM @temp WHERE ExpenseCategory = '01250A30-3865-40D2-9E49-DA2B9898B1F4') AS TotalMileage, 
(SELECT SUM(TotalAmount) FROM @temp WHERE ExpenseCategory = 'F4E4582D-DEDF-499D-BBC1-45003B865218') AS TotalEquip, 
(SELECT SUM(TotalAmount) FROM @temp WHERE ExpenseCategory = '55F471C1-6E52-4898-8263-0B7684B78E7C') AS TotalPPS, 
(SELECT SUM(TotalAmount) FROM @temp WHERE ExpenseCategory = '1EE0FC40-193F-4720-9143-0B61FFDE7B8D') AS TotalOther 
FROM @temp GROUP BY EmployeeId 

Can you try this? 
Usually when Group By is used it should be followed with "having" at the end. It should not be present in where condition

那肯定會給我這個表的總和。 –

最後添加條件Group By EmployeeId擁有EmployeeId =（或條件） –

獲取每個SQL行的總和
