== Why is this an issue?

Unused cursor parameters are misleading. Whatever the values passed to such parameters, the behavior will be the same.


=== Noncompliant code example

[source,sql]
----
cursor c_list_emp(pp_country varchar2, pp_status varchar2)  is -- Noncompliant pp_status is not used
   select e.employee_code,
          p.first_name,
          p.last_name,
          e.country
    from persons       p,
    join employee_list e on e.person_id = p.person_id
   where e.country = pp_country;
----


=== Compliant solution

[source,sql]
----
cursor c_list_emp(pp_country varchar2, pp_status varchar2)  is
   select e.employee_code,
          p.first_name,
          p.last_name,
          e.country
    from persons       p,
    join employee_list e on e.person_id = p.person_id
   where e.country     = pp_country
     and e.status_code = pp_status; -- use the parameter
----
or

[source,sql]
----
cursor c_list_emp(pp_country varchar2)  is -- Remove the parameter
   select e.employee_code,
          p.first_name,
          p.last_name,
          e.country
    from persons       p,
    join employee_list e on e.person_id = p.person_id
   where e.country = pp_country;
