这里很新，真的可以使用一些帮助。我有一张桌子

TimeID(pk), DateEntry(date), EntryTiem(time), 
ProjID(int), ProjName(varchar), Phone(bit), 
Research(bit), Notes(varchar), ProjActive(bit), 
TimeDateStamp(date).

我正在尝试将多行数据返回到每个 ProjName 但没有任何运气。这是我到目前为止想出的...

SELECT ProjName AS 'Project Name',  
    (SELECT CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 3600 AS varchar(12)) + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 60 % 60 AS varchar(2)),2)
     + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) % 60 AS varchar(2)), 2)
     FROM WorkTime
     WHERE Phone = 0 AND Research = 0 AND EntryTime IS NOT NULL
     ) AS 'Total Time No PMRE',     
    (SELECT CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 3600 AS varchar(12)) + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 60 % 60 AS varchar(2)),2) 
     + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) % 60 AS varchar(2)), 2) 
     FROM WorkTime
     WHERE Phone = 1 AND RESEARCH = 0 AND EntryTime IS NOT NULL
     ) AS 'Total Time Phone',
     (SELECT CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 3600 AS varchar(12)) + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 60 % 60 AS varchar(2)),2)
      + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) % 60 AS varchar(2)), 2)  
      FROM WorkTime
      WHERE Phone = 0 AND RESEARCH = 1 AND EntryTime IS NOT NULL
      ) AS 'Total Time Research',
      (SELECT CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 3600 AS varchar(12)) + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 60 % 60 AS varchar(2)),2)
       + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) % 60 AS varchar(2)), 2) 
       FROM WorkTime
       WHERE EntryTime IS NOT NULL
       ) AS 'TotalTime'
FROM WorkTime
WHERE EntryTime IS NOT NULL
GROUP BY ProjName

它返回以下...

Project Name   Total Time No PMRE   Total Time Phone   Total Time Research   Total Time
AAAA           19:06:15             2:00:00            1:00:06               22:06:21
BBBB           19:06:15             2:00:00        1:00:06               22:06:21
CCCC           19:06:15             2:00:00        1:00:06               22:06:21
DDDD           19:06:15             2:00:00        1:00:06               22:06:21

这是错误的。每列中的数量是该条件的总和，所有 ProjName 加在一起而不是单独分离出来。

这就是输出应该是什么......

Project Name   Total Time No PMRE   Total Time Phone   Total Time Research   Total Time
AAAA           00:00:19             0:00:00            0:00:00               00:00:19
BBBB           00:00:04             0:00:00        0:00:00               00:00:04
CCCC           03:00:00             2:00:00        1:00:06               06:06:06
DDDD           16:05:52             0:00:00        0:00:00               16:05:52

有没有人有任何建议或可以帮助我指出正确的方向？谢谢！

我认为您正在寻找的是有条件的 SUM：

SELECT ProjName AS 'Project Name',  
    SUM(CASE WHEN (Phone = 0 AND Research = 0 AND EntryTime IS NOT NULL) THEN DATEDIFF(second, 0, EntryTime) ELSE NULL END) AS 'Total Time No PMRE',
    SUM(CASE WHEN (Phone = 1 AND RESEARCH = 0 AND EntryTime IS NOT NULL) THEN DATEDIFF(second, 0, EntryTime) ELSE NULL END) AS 'Total Time Phone',
    SUM(CASE WHEN (Phone = 0 AND RESEARCH = 1 AND EntryTime IS NOT NULL) THEN DATEDIFF(second, 0, EntryTime) ELSE NULL END) AS 'Total Time Research',
    SUM(DATEDIFF(second, 0, EntryTime)) AS 'TotalTime'
FROM WorkTime
WHERE EntryTime IS NOT NULL
GROUP BY ProjName

将您的格式化代码添加到 SUM 的结果中，您会没事的

回答您对格式的评论，采用您的格式“模板”：

CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 3600 AS varchar(12)) + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 60 % 60 AS varchar(2)),2)
 + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) % 60 AS varchar(2)), 2)

并替换每次出现的SUM(DATEDIFF(second, 0, EntryTime)forSUM(CASE WHEN (Phone = 0 AND Research = 0 AND EntryTime IS NOT NULL) THEN DATEDIFF(second, 0, EntryTime) ELSE NULL END)

或者，您可以在包装源查询的查询中添加格式，如下所示：

SELECT CAST([Total Time No PMRE] / 3600 AS varchar(12)) + ':' + RIGHT('0' + CAST([Total Time No PMRE] / 60 % 60 AS varchar(2)),2)
    + ':' + RIGHT('0' + CAST(([Total Time No PMRE] % 60 AS varchar(2)), 2)
... -- The other columns
FROM (
    SELECT ProjName AS 'Project Name',
        SUM(CASE WHEN (Phone = 0 AND Research = 0 AND EntryTime IS NOT NULL) THEN DATEDIFF(second, 0, EntryTime) ELSE NULL END) AS 'Total Time No PMRE',
        SUM(CASE WHEN (Phone = 1 AND RESEARCH = 0 AND EntryTime IS NOT NULL) THEN DATEDIFF(second, 0, EntryTime) ELSE NULL END) AS 'Total Time Phone',
        SUM(CASE WHEN (Phone = 0 AND RESEARCH = 1 AND EntryTime IS NOT NULL) THEN DATEDIFF(second, 0, EntryTime) ELSE NULL END) AS 'Total Time Research',
        SUM(DATEDIFF(second, 0, EntryTime)) AS 'TotalTime'
    FROM WorkTime
    WHERE EntryTime IS NOT NULL
    GROUP BY ProjName
 ) AS ds

希望这可以帮助你

您需要将这些子查询与外部查询中的某些内容相关联，可能与您分组的内容相同：

SELECT ProjName AS 'Project Name',  
    (
        SELECT CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 3600 AS varchar(12)) + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 60 % 60 AS varchar(2)),2)
        + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) % 60 AS varchar(2)), 2)
        FROM WorkTime
        WHERE Phone = 0 AND Research = 0 AND EntryTime IS NOT NULL
            AND ProjName = a.ProjName -- Correlate to outer query
    ) AS 'Total Time No PMRE',     
    (
        SELECT CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 3600 AS varchar(12)) + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 60 % 60 AS varchar(2)),2) 
        + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) % 60 AS varchar(2)), 2) 
        FROM WorkTime
        WHERE Phone = 1 AND RESEARCH = 0 AND EntryTime IS NOT NULL
            AND ProjName = a.ProjName -- Correlate to outer query
    ) AS 'Total Time Phone',
    (
        SELECT CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 3600 AS varchar(12)) + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 60 % 60 AS varchar(2)),2)
        + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) % 60 AS varchar(2)), 2)  
        FROM WorkTime
        WHERE Phone = 0 AND RESEARCH = 1 AND EntryTime IS NOT NULL
            AND ProjName = a.ProjName -- Correlate to outer query
    ) AS 'Total Time Research',
    (
        SELECT CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 3600 AS varchar(12)) + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) / 60 % 60 AS varchar(2)),2)
        + ':' + RIGHT('0' + CAST(SUM(DATEDIFF(second, 0, EntryTime)) % 60 AS varchar(2)), 2) 
        FROM WorkTime
        WHERE EntryTime IS NOT NULL
            AND ProjName = a.ProjName -- Correlate to outer query
    ) AS 'TotalTime'
FROM WorkTime a -- Add alias
WHERE EntryTime IS NOT NULL
GROUP BY ProjName
