謝謝大家幫忙

Select 
    Sum(DateDiff(s, Toc1.OutTime, (Select Top 1 Intime 
            From tblTokenLogs 
            Where TokenId = Toc1.TokenId 
            And LogId != Toc1.LogId 
            And LogId > Toc1.LogId))) as Sec 
From 
    tblTokenLogs As Toc1 
Where 
    Toc1.TokenId = 1

錯字 - 這些總是比較容易，如果你格式化你的代碼被發現...... – sgeddes

您有一個額外的，不必要的' ）as'SecTotal'在你的'WHERE'子句的最後一行之後 - 只需刪除那行... –

remove）from LINE'And Toc1.OutTime！=''）as SecTotal' –

將此查詢與您的查詢進行比較，您將會明白出了什麼問題！

SELECT SUM(
      DATEDIFF(
       s, 
       Toc1.OutTime, 
       (
        SELECT TOP 1 Intime 
        FROM tblTokenLogs 
        WHERE TokenId = Toc1.TokenId 
          AND LogId != Toc1.LogId 
          AND LogId > Toc1.LogId 
       ) 
      ) 
     )    AS Sec 
FROM tblTokenLogs AS Toc1 
WHERE Toc1.TokenId = 1 
     AND Toc1.OutTime != ''

無用的別名) as SecTotal

現在顯示這種類型的錯誤「Can not perform an骨料e函數在包含聚合或子查詢的表達式上。「@ pedram – Herry

在末尾使用'GROUP BY Sec'。 – pedram

可能無法按秒排序顯示無效欄 – Herry

試試這個，

Select 
    Sum(DateDiff(s, Toc1.OutTime, Toc2.Intime)) as Sec 
From 
    tblTokenLogs As Toc1 
OUTER APPLY ( Select Top 1 Intime 
       From tblTokenLogs 
       Where TokenId = Toc1.TokenId 
        And LogId != Toc1.LogId 
        And LogId > Toc1.LogId 
       ) AS Toc2 
Where 
    Toc1.TokenId = 1 
    And Toc1.OutTime != ''
