Różnica daty między kolejnymi wierszami

Mam tabelę o następującej strukturze 

ID     Account Number     Date
1      1001               10/9/2011 (dd/mm/yyyy)
2      2001               1/9/2011 (dd/mm/yyyy)
3      2001               3/9/2011 (dd/mm/yyyy)
4      1001               12/9/2011 (dd/mm/yyyy)
5      3001               18/9/2011 (dd/mm/yyyy)
6      1001               20/9/2011 (dd/mm/yyyy)

Zasadniczo chciałbym mieć zapytanie dostępu, które oblicza różnicę dat dla kolejnych rekordów, ale dla tego samego numeru konta Oczekiwany wynik będzie !!

1001      10/9/2011 - 12/9/2011     2 days
1001      12/9/2011 - 20/9/2011     8 days
1001      20/9/2011                 NA

Zasadniczo to, co chciałbym zrobić, to mieć zapytanie dostępu, które oblicza różnicę dat dla kolejnych rekordów, ale dla tego samego numeru konta, w powyższym przykładzie byłoby 1001. (daty nie muszą być pokazywane w wynik)

Używam access 2003.

SELECT  T1.ID, 
        T1.AccountNumber, 
        T1.Date, 
        MIN(T2.Date) AS Date2, 
        DATEDIFF("D", T1.Date, MIN(T2.Date)) AS DaysDiff
FROM    YourTable T1
        LEFT JOIN YourTable T2
            ON T1.AccountNumber = T2.Accountnumber
            AND T2.Date > T1.Date
GROUP BY T1.ID, T1.AccountNumber, T1.Date;

Lub 

SELECT  ID,
        AccountNumber,
        Date,
        NextDate,
        DATEDIFF("D", Date, NextDate)
FROM    (   SELECT  ID, 
                    AccountNumber,
                    Date,
                    (   SELECT  MIN(Date) 
                        FROM    YourTable T2
                        WHERE   T2.Accountnumber = T1.AccountNumber

Możesz dodać Wyciąg WHERE dla numeru konta, jeśli jest to wymagane. Twoja tabela nazywa się t4 

SELECT 
   t4.ID, 
   t4.AccountNumber, 
   t4.AcDate, 
   (SELECT TOP 1 AcDate 
    FROM t4 b 
    WHERE b.AccountNumber=t4.AccountNumber And b.AcDate>t4.AcDate 
    ORDER BY AcDate DESC, ID) AS NextDate, 
   [NextDate]-[AcDate] AS Diff
FROM t4
ORDER BY t4.AcDate;

Spróbuj tego: 

select [Account Number], DATEDIFF(DD, min(date), max(date)) as dif
from your_table
group by [Account Number]

Odpowiedź Garethda zadziałała dla mnie idealnie.

FYI: jeśli potrzebujesz klauzuli ORDER BY, użyj jej na końcu zapytania SELECT w katalogu głównym.

SELECT  ConsignorID,
            DateRequired StartDate,
            NextDate,
            DATEDIFF("D", DateRequired, NextDate)
FROM (  SELECT  ConsignorID,
                DateRequired,
                (SELECT MIN(DateRequired) 
                 FROM "TABLENAME" T2
                 WHERE T2.DateRequired > T1.DateRequired
                ) AS NextDate
            FROM "TABLENAME" T1
        ) AS T

ORDER by T. DateRequired ASC
