我有以下查询，在此查询中，我选择了ebs表，其中包含一个自定义表，该表具有header_id并在自定义表XXREPORT_L1_TBL中填充数据。
我想调整此查询。
[update]对查询进行了更改：
在这些列的末尾添加了更新声明。

调整此查询几乎肯定没有简短的解决方案。这里的问题是它的大小和复杂性。缺乏表现仅仅是一种结果。
作为第一步，我会考虑从键盘上休息一下。拿一支笔和纸，用简单的英语（或您喜欢的“人类”语言）通过此查询从数据库中写下您想要回答的问题。那么问问自己你真的需要回答哪些列/变量/属性来回答这些问题？也要写下来。
现在，您真的需要所有这些列，嵌套连接，选择等来生成这些变量吗？也许，但可能不是。这里的关键点是只关注你需要的数据/信息（YAGNI），并从那里绘制出一张图片，显示你需要产生回答你问题的信息的裸体关系。换句话说，从外部工作，而不是相反。
我意识到这听起来有点抽象和模糊，但重点是保持清晰简单的代码始终是一场持续的斗争。密切关注手头的目标将有助于保持你的头脑。
最后，一些更具体的想法一目了然：
