Sort(Order by) a cursor by cursor parameter

Question

Hello,
I want to make cursor to query three column data, and order by the paramter when calling store procedure. But the cursor did not order by column name at all.
Any help will be appreciated.

My package/procedure:
CREATE OR REPLACE PACKAGE test_PKG AUTHID DEFINER
AS
TYPE REF_CUR IS REF CURSOR;
PROCEDURE test_proc(COLN IN VARCHAR2, OUTCUR OUT REF_CUR);
END test_PKG;
CREATE OR REPLACE PACKAGE BODY TEST_PKG
AS
PROCEDURE test_proc(COLN in varchar2, outcur out ref_cur) IS
BEGIN
     IF NOT OUTCUR%ISOPEN
     THEN
          open OUTCUR FOR
          SELECT      CPS.PYROL_ID,
               CPS.VEND_ID,
               CPS.CONT_ID
          FROM      EPRS.CNTRCTR_PYROL_SUBMIT CPS
          ORDER BY COLN; <------What should be here?
     END IF;
end test_proc;
end test_pkg;
var results refcursor;
execute test_PKG.test_PROC('Vend_ID', :results);
print results;
It gave me results:
PYROL_ID VEND_ID CONT_ID
193 06883 009214070
196 11756 202101064
205 06507 072202046
206 06507 042202046
207 06507 032202046
208 06883 012202046

Answer 1

I could make the question more clear;
I want to query a table, for example, with three columns. The query results should be sorted by one specific column. I want to leave the column to be ordered by as a parameter, how to implment it?
Thanks.
