I have a simple table with one key field and some other non-key attributes. I need to generate an output file with some select query data every time i run the script. But the problem is the output file should be dynamically named on the key column it is selecting each time.

E.g. if we are selecting the [name], [age], [emp_id](pk) and [designation] of the highest salaried employee by running the script, the output file should be named
[emp_id].txt and it should contain
[name]
[age]
[emp_id]
[designation]

Not sure if I understood your problem correctly, but if you run the select and when looping through the result you decide the file name.

So something like:

SQL

DECLARE
  emp_rec employee%ROWTYPE;
  CURSOR cur_emp IS SELECT e.*
                    FROM   employee e
                    WHERE  ...the conditions..;
   emp_file UTL_FILE.FILE_TYPE;
BEGIN
   OPEN cur_emp;
   FETCH cur_emp INTO emp_rec;
   WHILE cur_emp%FOUND LOOP
      emp_file := UTL_FILE.FOpen('directory', TO_CHAR(emp_rec.emp_id) || '.txt','w'); 
      UTL_FILE.Put_Line(emp_file, ...data to write..., 1); 
      UTL_FILE.FClose(emp_file);    
   END LOOP;
   CLOSE cur_emp;
END;
