我想要的是在X2中找到公共值，然后返回X1 在本例中，我想得到42974和42975，因为它们共享相同的X2

我使用这个查询，但它不返回任何内容

SELECT 
TT.X1
  FROM TEST12 TT
group by TT.WORK_ORDER 
having count(distinct TT.X2) = (select count (distinct tt2.X2) from TEST12 tt2)

但是如果我从数据中删除42858，它将返回42974和42975

请告知

谢谢，旅行者

尝试加入：

SELECT DISTINCT T1.X1
FROM TEST12 T1
JOIN TEST12 T2 ON T1.X2 = T2.X2
    AND T1.X1 != T2.X2

如果有三行或更多行共享一个

X2

值，则需要使用

DISTINCT

。如果最多只有两行共享

X2

值，则可以省略

DISTINCT

关键字。

我知道您希望X1值共享其所有X2值
此解决方案适用于Oracle 11g R2

这里有一些选择。 X2元素的数量有限制，因为它们被连接到单个字符串

select    count (*)                                   as x2_within_group
         ,x2_elements
         ,listagg (x1,',') within group (order by x1) as x1_list


from     (select    X1
                   ,listagg (x2,',') within group (order by x2) as x2_list
                   ,count (*)                                   as x2_elements

          from      TEST12

          group by  X1
          )


group by  x2_list
         ,x2_elements
;

errorORA-01722:无效号码01722。00000-“无效数字”*原因：指定的数字无效*操作：指定一个有效的数字。谢谢Dudu，我们还可以添加X2的总计数相似性吗？@TRIEZEREN，你的意思是，每个X1有多少个X2值？我们还可以使用附加分组rankThanks Dudu使其像pivot一样。它起作用了，我正在用pivot的相同数据创建另一个问题output@TRIEZEREN太好了（附言，如果你喜欢这个答案，你可能想投它一票）
