如何提取在函数/过程中使用的所有Oracle关键字

Question

Is there any easy way to fetch all the Oracle key words used In a function/procedure?

The first thing that strikes me Is to split the text from user_source for the given object name based on space but this will leave few scenarios uncovered like DBMS_OUTPUT.PUT_LINE('HELLO WORLD') etc.,

Is there any other way rather than split by space, dot, paranthesis?

You could use built-in ALL_STATEMENTS / ALL_IDENTIFIERS .

ALL_STATEMENTS describes all SQL statements in stored PL/SQL objects accessible to the user.

And The Power of Cloud PL/SQL :

To gather information about PL/SQL identifiers and SQL statements in your code base, execute the following statement in your session

ALTER SESSION SET plscope_settings='identifiers:all, statements:all';
-- function/package compilation

SELECT st.owner,
       st.object_name,
       st.line,
       s.text
  FROM all_statements st join all_source s
    ON ( st.owner = s.owner
   AND st.object_name = s.name
   AND st.line = s.line )
 WHERE st.TYPE IN ('EXECUTE IMMEDIATE', 'OPEN')
