SQL Server存儲過程問題。從數據庫中獲取多個結果

Question

這是我的存儲過程，以獲取在StartDate和EndDate之間工作的員工及其小時數的列表。

ALTER procedure [dbo].[usp_get_employeehourlyreport] 
    @startdate datetime, 
    @enddate datetime 
as 
begin 
    select * 
    from (
     select 
     (select FullName from Registration 
      where Registration.UserId = UserTime.UserId) Fullname, 
     ISNULL(SUM(HoursWorked), 0) HoursWorked 
     from UserTime 
     where CheckIn between @startdate and @enddate 
     group by UserId, CheckIn) tbl 
end 

我得到的結果是：

Fullname    HoursWorked 
    Antonio Jake   0 
    Antonio Jake   0.016666 

所以基本上它會顯示一個額外的行與小時0我沒有在我的數據庫中的任何重複的全名。

表結構是：

USERTIME：

UserTimeId int    Unchecked 
    UserId  int    Checked 
    CheckIn  datetime  Checked 
    LoginStatus nvarchar(50) Checked 
    Day   varchar(50)  Checked 
    HoursWorked float   Checked 
    Date   nvarchar(50) Checked 

REGISTRATION：

UserId int Unchecked 
    FullName varchar(50) Checked

嘗試是這樣的....

ALTER procedure [dbo].[usp_get_employeehourlyreport] 
@startdate datetime, 
@enddate datetime 
AS 
BEGIN 
SET NOCOUNT ON; 

    SELECT R.FullName, ISNULL(SUM(UT.HoursWorked),0) AS Total_Hours 
    FROM Registration R LEFT JOIN USERTIME UT 
    ON R.UserId = UT.UserId                             Fullname ,ISNULL(SUM(HoursWorked),0) HoursWorked from UserTime 
    AND UT.CheckIn >= @startdate 
    AND UT.CheckIn <= @enddate 
    GROUP BY R.FullName 
END
