您如何以编程方式识别存储过程的依赖关系?

本文介绍了您如何以编程方式识别存储过程的依赖关系?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

是否可以编写PL/SQL查询来标识存储过程依赖项的完整列表?我只对标识其他存储过程感兴趣，并且我也不希望限制嵌套的深度，因为嵌套的深度也不会太大.例如，如果A呼叫B，而C呼叫D，则我希望B，C和D被报告为对A的依赖.

Is it possible to write a PL/SQL query to identify a complete list of a stored procedures dependencies? I'm only interested in identifying other stored procedures and I'd prefer not to limit the depth of nesting that it gets too either. For example, if A calls B, which calls C, which calls D, I'd want B, C and D reported as dependencies for A.

推荐答案

在此页面，您将找到以下查询，该查询使用 PUBLIC_DEPENDENCY 字典表:

On this page, you will find the following query which uses the PUBLIC_DEPENDENCY dictionary table:

SELECT lvl , u.object_id , u.object_type , LPAD (' ', lvl) || object_name obj FROM ( SELECT LEVEL lvl, object_id FROM SYS.public_dependency s START WITH s.object_id = ( SELECT object_id FROM user_objects WHERE object_name = UPPER ('&OBJECT_NAME') AND object_type = UPPER ('&OBJECT_TYPE')) CONNECT BY s.object_id = PRIOR referenced_object_id GROUP BY LEVEL, object_id) tree , user_objects u WHERE tree.object_id = u.object_id ORDER BY lvl /
