【问题描述】：
我知道这曾经是这里的一个话题，但我仍然无法在工会中进行分组。我看过这里：Grouping and Joining a Unioned Table. Having Problems 等等，但仍然对如何处理括号感到困惑。这是我的代码：

错误是：
ORA-00907: 缺少右括号
00907. 00000 - “缺少右括号”
*原因：
*行动：
行错误：152 列：23
我已经尝试了许多不同的括号位置排列并了解它应该如何工作，但我似乎仍然无法掌握将它们放在哪里（或者这是否是问题所在）。
TIA 为您提供任何帮助！
【问题讨论】：
-
UNION ALL之前需要有一个结束括号。解决此问题后，您对列的引用需要工作（引用封装在派生表中的别名）。 -
谢谢帕特里克，通过引用您所说的结束组和排序的列？
-
例如，
W.WORK_ORDER_NO（查询块一），应该以它来自的派生表的名称作为前缀（但您没有分配一个）或没有限定（因为一切都来自您的派生表）。 -
顺便说一句，帮自己一个忙，使用检测这些配对的工具（例如好的文本编辑器）或开发工具。
