Question

I need a generalized method to get list of runtime parameters (values) when I call a procedure. I need something similar to the $$PLSQL_UNIT that returns the name of the running procedure.
(plsql Oracle 10g)

E.g. look at this sample procedure:
(it simply prints its own name and parameters )

CREATE OR REPLACE PROCEDURE  MY_PROC(ow in varchar2, tn IN varchar2)
 IS

BEGIN
     dbms_output.put_line('proc_name: '||$$PLSQL_UNIT||' parameters: '|| ow||' '||tn  );

    EXCEPTION
    WHEN OTHERS THEN 
       DBMS_OUTPUT.PUT_LINE('ERRORE: ' ||SQLERRM);

END MY_PROC;
/

Running procedure produces the following output:

SQL> 
  1   BEGIN
  2     IBAD_OWN.MY_PROC('first_par', 'second_par');
  3   END;
  4  /

proc_name: MY_PROC parameters: first_par second_par

PL/SQL procedure successfully completed.

I’m not satisfy because I can’t copy and paste in all my procedures because I have to hard code each procedure to set their right parameter variables.

Thanks in advance for the help.

It isn’t possible to dynamically retrieve the values of parameters passed to a procedure in Oracle PL/SQL. The language simply isn’t designed to handle this kind of operation.

Incidentally, in a procedure that is located within a package, $$PLSQL_UNIT will only return the package’s name. I find it’s better to define a consistently-named constant within each procedure that contains the procedure’s name.
