exception when others then 
   -- handle the exception
end;

insert into user_permissions select distinct user_id,sales_person_name,sales_mgr_name,upper(pcd(i)),upper(acd(i)) from user_permissions where sales_person_name=sales_person and concat(upper(pcd(i)),upper(acd(i))) not in (select concat(upper(pcode),upper(acode)) from user_permissions) and rownum<2 ;
