我正在尝试显示每个用户在一周内花费的时间（内部或外部工作）但时间都在桌子上的同一列上，是否可以将其拆分为 2 个不同的列并仍然拥有它这样它只显示每个用户一次，而不是每次他们输入时间时，这可能在一周内多次显示。

下面的 SQL 为我提供了每个用户在一周内跟踪的时间，但内部和外部在不同的行上。

SELECT SUM(FilteredMag_Time.mag_hoursspent) AS Time, 
       FilteredSystemUser.fullname, 
       FilteredMag_project.mag_typename
  FROM FilteredSystemUser 
INNER JOIN FilteredMag_Task 
INNER JOIN FilteredMag_project ON FilteredMag_Task.mag_projectid = FilteredMag_project.mag_projectid 
INNER JOIN FilteredMag_Time ON FilteredMag_Task.mag_taskid = FilteredMag_Time.mag_taskid 
                            ON FilteredSystemUser.systemuserid = FilteredMag_Time.createdby
     WHERE (FilteredMag_Time.mag_starttime BETWEEN DATEADD(dd, - (DATEPART(dw, GETDATE()) - 1), GETDATE()) 
                                               AND DATEADD(dd, - (DATEPART(dw, GETDATE()) - 7), GETDATE()))
GROUP BY FilteredSystemUser.fullname, FilteredMag_project.mag_typename
ORDER BY FilteredSystemUser.fullname

这是当前输出的示例。

Time                fullname             mag_typename
------------------ --------------------- -------------------------
1.2500000000        David Sutton        External
8.2500000000        Gayan Perera        External
9.0000000000        Paul Nieuwelaar     Internal
14.8700000000       Roshan Mehta        External
6.0000000000        Roshan Mehta        Internal
2.7800000000        Simon Phillips      External
4.6600000000        Simon Phillips      Internal

您可以使用 SQL Server PIVOT。

就像是

DECLARE @Table TABLE(
        userID INT,
        typeID VARCHAR(20),
        TimeSpent FLOAT
)

INSERT INTO @Table SELECT 1, 'INTERNAL', 1
INSERT INTO @Table SELECT 2, 'INTERNAL', 1
INSERT INTO @Table SELECT 1, 'INTERNAL', 1
INSERT INTO @Table SELECT 1, 'INTERNAL', 1
INSERT INTO @Table SELECT 2, 'EXTERNAL', 3
INSERT INTO @Table SELECT 1, 'EXTERNAL', 3

SELECT  *
FROM 
(
    SELECT  userID, typeID, TimeSpent
    FROM    @Table
) s
PIVOT   (SUM(TimeSpent) FOR typeID IN ([INTERNAL],[EXTERNAL])) pvt

输出：

userID      INTERNAL               EXTERNAL
----------- ---------------------- ----------------------
1           3                      3
2           1                      3

假设FilteredMag_project.mag_typename是“内部”或“外部”，请尝试以下操作：

SELECT SUM(CASE FilteredMag_project.mag_typename 
                WHEN 'INTERNAL' THEN FilteredMag_Time.mag_hoursspent
                ELSE 0 END) AS InternalTime, 
       SUM(CASE FilteredMag_project.mag_typename 
                WHEN 'EXTERNAL' THEN FilteredMag_Time.mag_hoursspent
                ELSE 0 END) AS ExternalTime, 
       FilteredSystemUser.fullname
  FROM FilteredSystemUser 
INNER JOIN FilteredMag_Task 
INNER JOIN FilteredMag_project ON FilteredMag_Task.mag_projectid = FilteredMag_project.mag_projectid 
INNER JOIN FilteredMag_Time ON FilteredMag_Task.mag_taskid = FilteredMag_Time.mag_taskid 
                            ON FilteredSystemUser.systemuserid = FilteredMag_Time.createdby
     WHERE (FilteredMag_Time.mag_starttime BETWEEN DATEADD(dd, - (DATEPART(dw, GETDATE()) - 1), GETDATE()) 
                                               AND DATEADD(dd, - (DATEPART(dw, GETDATE()) - 7), GETDATE()))
GROUP BY FilteredSystemUser.fullname
ORDER BY FilteredSystemUser.fullname
