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，出现以下错误：

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更正语句。

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，而无需重新构建每个脚本。有任何想法吗？

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，以将准确的查询放入变量中。

为了自动清理一堆查询，你可以把它变成一个存储过程，并在查询文件中写一些东西到光标，将它们的文本拉到一个变量中，将变量传递给存储过程并将结果输出到一个新文件。

Declare @query Varchar(Max),
        @columns Varchar(Max),
        @from Varchar(Max),

        @checkChar Varchar(1),
        @counter Int = 0,
        @newColumns Varchar(Max);;

Declare @indexes Table (tID Int Identity, indexLoc Int, indexChar Varchar(1))
Declare @colNames Table (tID Int, colName Varchar(512))
