需要sub-select，因为我需要将字段“ GROUP BY”压缩成一行，而不是将每个LISTAGG的记录都压缩成一行。

只要不包括注释掉的部分，下面的查询就可以正常工作。我需要添加注释掉的行。

我不确定您的问题为何与LISTAGG()有关。看来与这个问题无关。

您的子查询是：

(SELECT afl.aflfldc
 FROM fty inner join
      afl
      ON afl.aflftykeyi = fty.ftykeyi
 WHERE fty.ftybezc = 'MDVDesc' and
       AFL.AFLARTKEYI = ART.ARTKEYI and
------------------------^ correlation columns
       AFL.AFLKAVKEYI = ART.ARTKAVKEYI
------------------------^
) as "MDVDesc",

我突出显示了相关性列。在聚合查询中，它们应该在GROUP BY中，但不在。因此，Oracle感到困惑。您是说要按某些列进行汇总。然后，您需要其他人的关联。

我认为聚合函数可以解决该问题：

(SELECT afl.aflfldc
 FROM fty inner join
      afl
      ON afl.aflftykeyi = fty.ftykeyi
 WHERE fty.ftybezc = 'MDVDesc' and
       AFL.AFLARTKEYI = MAX(ART.ARTKEYI0 and
------------------------^ correlation columns
       AFL.AFLKAVKEYI = MAX(ART.ARTKAVKEYI)
------------------------^
) as "MDVDesc",

但是，老实说，我一般不会在聚合查询中看到像这样的子查询的需要；通常有另一种编写逻辑的方法。
