Java Programming

Why?

Do you have such a scenario that you don't know the procedure name you're trying to compile?

Simple answer is you can't - without generating some additional metadata for the package.

One way to generate the metadata would appear to be PL/Scope in 11g but I haven't actually tried that to see how it pans out.

There's $$PLSQL_UNIT compiler directive but it doesn't reference subprograms in a package, only the package itself :

SQL> create or replace package mypck is
  2    procedure myprc;
  3  end;
  4  /
 
Package created
 
SQL> 
SQL> create or replace package body mypck is
  2    procedure myprc is
  3    begin
  4      dbms_output.put_line('I''m in '||$$PLSQL_UNIT);
  5    end;
  6  end;
  7  /
 
Package body created
 
SQL> exec mypck.myprc;
 
I'm in MYPCK
 
PL/SQL procedure successfully completed
 

This might help you understand the problem:

Buit I usually hardcode the proc name into a variable and use that for logging.

You've posted enough to know that you need to provide your 4 digit Oracle version (result of SELECT * FROM V$VERSION).

is it possible to obtain a called procedure/function name within package?

For a measuring and tracing purpose, I would like to store an info at the beginning of each procedure/function in package with timestamp + additional details if needed.
>
I usually use this method

1. Create a SQL type for logging information
2. Put the package name into a constant in the package spec
3. Add a line to each procedure/function for the name.

Sample package spec

	/******************************************************************************
	 * Constants and package variables
	 ******************************************************************************/
		gc_pk_name			CONSTANT VARCHAR2(30) := 'PK_TEST';

Sample procedure code in package

	 PROCEDURE P_TEST_INIT
	 IS
	   c_proc_name CONSTANT VARCHAR2(80)  := 'P_TEST_INIT';
	   v_log_info  TYPE_LOG_INFO := TYPE_LOG_INFO(gc_pk_name, c_proc_name); -- create the log type instance

	 BEGIN
		NULL; -- code goes here
	 EXCEPTION
	 WHEN ??? THEN
		v_log_info.log_code := SQLCODE;  -- add info to the log type
		v_log_info.log_message := SQLERRM;
		v_log_info.log_time    := SYSDATE;
		pk_log.p_log_error(v_log_info);
                                raise;
	 END P_PK_TEST_INIT;

Sample SQL type

DROP TYPE TYPE_LOG_INFO;

CREATE OR REPLACE TYPE TYPE_LOG_INFO AUTHID DEFINER AS OBJECT (
/* *****************************************************************************
 *  NAME:      TYPE_LOG_INFO
 *  PURPOSE:   Holds info used by PK_LOG package to log errors.
 *
 *             Using a TYPE instance keeps the procedures and functions
 *             independent of the logging mechanism.
 *
 *             If new logging features are needed a SUB TYPE can be derived
 *             from this base type to add the new functionality without
 *             breaking any existing code.
 *
 *  REVISIONS:
 *  Ver        Date        Author           Description
 *
 *   1.00      mm/dd/yyyy  me               Initial Version.

And as shown in my post, this doesn't apply to subprograms in a package, which seems to be precisely what OP is after.

Thanks - brain f*** - didn't even see your post somehow. I update my post with the old method.
