Question

我在table数据库中有一个Oracle。我想逐行获取具有相同列值的数据。例如：

1   871412  007607000176    12.02.2015 15:03:29 007607000176    ELTN    007607000176    ELTN    52079   28  156608  654108
2   753281  007607000176    23.01.2014 13:13:38 007607000176    ELTN    007607000176    ELTN    43494   24  82860   580360
3   739033  007607000176    23.01.2014 13:10:53 007607000176    ELTN    007607000176    ELTN    43494   24  82860   580360
4   528902  007607000176    22.02.2013 16:19:37 007607000176    ELTN    007607000176    ELTN    46776   26  19521   517021
5   468832  007607000176    15.02.2012 16:00:58 007607000176    ELTN    007607000176    ELTN    44708   32  10395   442895
6   36782   007607000176    01.04.2011  007607000176    ELTN    007607000176    ELTN                
7   36781   007607000176    01.04.2010  007607000176    ELTN    007607000176    ELTN                
8   36780   007607000176    01.04.2009  007607000176    ELTN    007607000176    ELTN                
9   36779   007607000176    30.12.2007  007607000176    ELTN    007607000176    PRTG                
10  36778   007607000176    01.04.2007  007607000176    PRTG    007607000176    BASC                
11  36777   007607000176    01.04.2006  007607000176    BASC    007607000176    PRTG                
12  36776   007607000176    01.04.2005  007607000176    PRTG    007607000176    PRTG

我想像下面一行一行6-7-8行。因为他们的一些列是相同的。

ELTN    007607000176    ELTN                
ELTN    007607000176    ELTN                
ELTN    007607000176    ELTN

我希望表中的所有记录都像这种情况一样逐行。我该怎么办？

修改

我使用WITH子句来解决这个问题。首先，我带了组的数据。之后我逐行提供了重复的数据信息。

一种解决方案可能是将表连接到自身，并检查除id之外的每个相关列是否相同。因此，除了id：

之外，如果您的行具有完全相同的数据，则只能获得一个联接

   Select a.colname, a.colname, a.colname from table as a
   inner join table as b on a.Id != b.ID 
  and a.date = b.date and a.Code = b.Code ... all other relevant columns... and a.code2 = b.code2

根据oracle中的某些条件获取逐行数据
