我正在尝试将此Oracle Discoverer创建的SQL脚本转换为可以从发现者外部运行的查询。当我尝试运行脚本时，我收到以下错误：
SQL语句无效，因为它包含以下重复的列名：LEAF_DETAILS，LEAF_DETAILS_DESCR，LEAF_DETAILS，LEAF_DETAILS_DESCR。通过为列提供别名来纠正该语句。
我必须转换大约100个这样的脚本，所以我正在寻找一种方法来轻松修改此脚本输出而无需重建每个脚本。有什么想法吗？

这将做你想要的。这很丑陋，但它会完成工作。只需将查询粘贴到@query变量中，然后按F5;输出是您的新查询。您需要用两个撇号替换任何单个撇号，以获得对变量的确切查询。
要自动清理一堆查询，您可以将其转换为sproc并通过查询文件向光标写入内容，将其文本拉入变量，将变量传递给sproc并将结果输出到新的文件。

通过位置而不是 name 引用分组列，例如：
select col1, col2, sum(col3), col4
from table
group by 1, 2, 4;
仅供参考，此语法选项是SQL标准的一部分，适用于所有SQL数据库。
