MAX在SQL中的日期範圍

Question

MAX來自多個記錄的日期範圍

我有一張如下所示的表格。

Customer Publication Start Date End Date 
1 S0048 DLD   01-JAN-2013 15-NOV-2013 
2 S0048 DLD   03-MAR-2013 31-DEC-2013 
3 S0048 SLD   01-FEB-2013 31-DEC-2013 
4 S0048 SLD   01-FEB-2013 30-NOV-2013 
5 S0145 DLD   01-JAN-2013 01-MAR-2013 
6 S0145 DLD   02-FEB-2013 28-NOV-2013 

我需要通過給出結束日期範圍來得到結果。 例如：如果輸入：end date 01-NOV-2013 to 30-NOV-2013（搜索誰是11月一個月到期）

結果應該是

S0145 DLD   02-FEB-2013 28-NOV-2013 

請注意，第一和第四的記錄不應該出現，因爲他們有更新其出版認購期。

我怎樣才能得到這些結果。請幫忙。

親愛的所有人，我可以得到給定日期範圍的數據。但它返回1，4，6。我只需要記錄6即可獲得回報。因爲我需要某個出版物的特定客戶的最新日期範圍（每個客戶每個出版物的最高日期範圍）。至於我的輸入（搜索11月份結束日期）。因爲該客戶已經延長了「DLD」期限，因此1沒有必要。第4條記錄也是如此。第四不需要，延續（更新）中記錄3

Answer 1

你很可能STR_TO_DATE用於此目的：

http://dev.mysql.com/doc/refman/5.1/en/date-and-time-functions.html#function_str-to-date

例如：

SELECT MAX(STR_TO_DATE(`Start Date`, '%d-%b-%Y')) FROM customers 

的格式說明（%d等）在這裏列出：

在TSQL可以編寫一個查詢爲：

SELECT T2.customer, 
     T2.publication, 
     T2.startdate, 
     T2.enddate 
FROM table1 T2 
     INNER JOIN (SELECT t1.customer, 
          Max(t1.enddate) AS MaxEnddate 
        FROM table1 T1 
        GROUP BY t1.customer, 
          T1.publication) T 
       ON T.customer = T2.customer 
        AND T.maxenddate = T2.enddate 
WHERE T2.enddate BETWEEN '01-NOV-2013' AND '30-NOV-2013' 

更新：

     hca_sub.account_number subscriber_code, 
     hp_sub.party_name subscriber_name, 
     sum(xssl.quantity) qty, 
     msi.segment1 Publication_name,
