PL/SQL 中的 Oracle 数据库依赖项 [英] Oracle database dependencies in PL/SQL

问题描述

我需要找到函数/过程(在包体内部定义)和它们使用的表之间的依赖关系.

I need to find dependencies between functions/procedures(defined inside package bodies) and tables which they use.

我已经尝试过 all_dependencies 但它仅适用于包级别，而不适用于内部函数/过程级别.是否有可能使用例如找到此依赖项all_source?

I've tried all_dependencies but it works only on the package-level, not the inner function/procedure-level. Is there any possibilty to find this dependencies using e.g. all_source?

预先感谢您的帮助.

推荐答案

无法找到过程(在包中)和表之间的依赖关系.

It is not possible to find the dependencies between procedures (in a package) and tables.

有多种工具可以检查依赖关系.正如您已经发现的那样，*_DEPENDENCIES 仅跟踪每个包级别的对象依赖关系.有一个简洁的工具 PL/Scope跟踪包各部分之间的依赖关系.但它确实不会跟踪所有表引用.

There are several tools to examine dependencies. As you've already discovered, *_DEPENDENCIES only tracks object dependencies on a per-package level. There is a neat tool PL/Scope that tracks dependencies between parts of a package. But it does it does not track all table references.

理论上你可以使用*_SOURCE.实际上，这是不可能的，除非您的代码使用一组有限的功能.对于任何中等复杂的代码，不要使用字符串函数或正则表达式来解析代码.不幸的是，似乎没有任何可编程且能够准确解析复杂代码的 PL/SQL 解析器.

Theoretically you could use *_SOURCE. In practice, this is impossible unless your code uses a limited set of features. For any moderately complicated code, forget about using string functions or regular expressions to parse code. Unfortunately there does not seem to be any PL/SQL parser that is both programmable and capable of accurately parsing complex code.

说这不可能"并不是一个好的答案.但在这种情况下，它可能会为您节省大量时间.这是很容易陷入死胡同并浪费大量精力的任务之一.

Saying "it's not possible" isn't a great answer. But in this case it might save you a lot of time. This is one of those tasks where it's very easy to hit a dead end and waste a lot of effort.
