U need to create ur own function. Its not available. u can use following query

select column_name
from all_tables
where table_name = p_table_name
and owner = p_owner_name;

SQL> create or replace procedure p (tab in varchar2, col in varchar2, cur out sys_refcursor)
  2  is
  3  begin
  4    open cur for 'select '||col||' from '||tab;
  5  end;
  6  /

Procedure created.

SQL> var v refcursor
SQL> exec p('T','VAL',:v);

PL/SQL procedure successfully completed.

SQL> print v;
VAL

I don't know PL/SQL Developer but I can't imagine a tool that does not know cursor.

I transfer this thread to SQL Client Tools forum.

I meant this may not be the syntax.
There may be another syntax.
But there surely is a way to declare a cursor.
Did you check in the documentation?
Otherwise, wait for someone.
