Question

我的表名是ProductDirection。它包括这些列。

操作代码
messagecode
productno
messages_info
的StatusCode
insertdate

我有一个批处理程序，这个程序最大化。一个产品一天3次。如果产品的操作成功批次，当天批次对该产品不起作用。所以程序在成功的同时工作并且插入记录失败或成功。

我的记录是：

ProductNo  StatusCode  MessagesInfo     InsertDate
---------------------------------------------------------   
1236895     0          Fail For xxx     01.01.2013 10:00:00
1236895     0          Fail For yyy     01.01.2013 15:00:00
1236895     1          Success          01.01.2013 19:00:00
1236895     0          Fail For xxx     15.01.2013 10:00:00
1236895     0          Fail For yyy     15.01.2013 15:00:00
1236895     0          Fail For zzz     15.01.2013 19:00:00

我想要这个条件。如果它有可用的成功记录，我想只在一天内得到这个记录，如果所有记录都是一天的结果。所以我的记录看起来像这样。

ProductNo  StatusCode MessagesInfo    InsertDate
------------------------------------------------------    
1236895     1         Success         01.01.2013 19:00:00 
1236895     0         Fail For xxx    15.01.2013 10:00:00
1236895     0         Fail For yyy    15.01.2013 15:00:00
1236895     0         Fail For zzz    15.01.2013 19:00:00

我该如何解决？

SELECT *
  FROM ProductDirection p
 WHERE p.operationcode = 6
   AND p.messagecode = 2
   AND trunc(p.insertdate) BETWEEN '01.01.2013' AND '21.06.2013';

Answer 1

试试这个。

编辑：

SELECT *
  FROM productdirection
 WHERE (productno, TRUNC (insertdate)) IN (
                                        SELECT   productno,
                                                 TRUNC (insertdate)
                                            FROM productdirection
                                        GROUP BY productno,
                                                 TRUNC (insertdate)
                                          HAVING MAX (statuscode) = 0)
    OR statuscode = 1;

根据需要添加任何其他where子句。

WITH ProductDirection AS
(
SELECT 1236895 ProductNo, 0 StatusCode, 'Fail For xxx' MessagesInfo, TO_DATE('01.01.2013 10:00:00', 'DD.MM.YYYY HH24:MI:SS') InsertDate FROM DUAL UNION ALL
