Question

我正在尝试从2个单独的模式中收集数据。由于单个查询的复杂性将导致所有数据都会使数据库服务器崩溃，我制作了单独的表并用我需要的所有数据填充它们。现在我只需要合并数据并匹配列，以便以后可以删除任何重复的行。下面是我创建的两个查询，用于返回我要查找的结果。我的问题是，当我运行第二个查询时，我收到以下错误：

   Error at Command Line:7 Column:4
   Error report:
   SQL Error: ORA-00904: "BOF_FOR_CHUCKSIMPSON"."BATCH_ID": invalid identifier
   00904. 00000 -  "%s: invalid identifier"
   *Cause:    
   *Action

有人可以帮我理解发生了什么吗？

Answer 1

您在create table语句中使用双引号中的混合大小写名称，如下所示：

bbp.BATCH_ID "Batch ID"

因此，您在该表中没有一个名为BATCH_ID的列，而是一个名为“批次ID”的列，它只能被引用 - 即大小写混合和双引号。

在Oracle中合并和匹配数据
