Question

What I need to do is to create oracle user which will see only procedures and functions headers, without bodies.

Any idea how I can achieve that, what kind of privileges should be set?

Answer 1

Creating a view with a DBA account and granting SELECT on this view should work:

CREATE VIEW dba_source_pkg_headers AS
SELECT *
  FROM dba_source
 WHERE type = 'PACKAGE';

GRANT select ON dba_source_pkg_headers TO your_user;

---

update: this would not work with unpackaged functions and procedures. I don’t think you can separate header and body with regular functions/procedures.

If you use regular functions and procedures, you could grant select on dba_arguments, this would give you access to all function/procedure parameters.
