procedures with optional variables

create or replace PROCEDURE Get_ent_copy (TC in number,us in VARCHAR2) IS
  
    Cursor c_ent IS
 select * From master_gen_ledger
 Where  (doc_date >= st_month and doc_date <= en_month)
    and tr_code  =tc
    and user=us;

Open in new window


for me , us , is optional , mean
if us , then the cursor syntax will be as above
if us = null , then the syntax will be

    Cursor c_ent IS
 select * From master_gen_ledger
 Where  (doc_date >= st_month and doc_date <= en_month)
    and tr_code  =tc;
  

Open in new window


how could i identify the cursor in that procedure ?

What about something like this:

create or replace PROCEDURE Get_ent_copy (TC in number,us in VARCHAR2 default null) IS
  
    Cursor c_ent IS
 select * From master_gen_ledger
 Where  (doc_date >= st_month and doc_date <= en_month)
    and tr_code  =tc
    and user=nvl(us, user);
