Passing table record to a function in a query

Question

I have a procedure which calls a function in a query which has 2 input parameters as shown below -
select a.id, a.name, a.sal, check_xyz_func(a.id, a.sal) from employees a
The function check_xyz_func retiurns varchar2.
Now the requirement is that few more columns from the same table are needed as input to this function. So instead of giving all the column names,. can i pass the entire row as input to this function. Something like => check_xyz_func (a.*).
I tried creating a type --> TYPE rec IS TABLE OF employees%ROWTYPE and passing rec to this function, but this isn't working.

And what should i pass as parameter when calling the function

I showed you what to pass. You should pass a variable that is declared as
employee_rec employees%ROWTYPESo you would populate 'employee_rec' and pass it to the function.
See the pipelined function code below that declares a variable of %ROWTYPE and does a fetch into it.
    l_rec  emp%rowtype;
      fetch emp_cv into l_rec;You would then pass 'l_rec' to your function.
-- type to match emp record
create or replace type emp_scalar_type as object
  (EMPNO NUMBER(4) ,
   ENAME VARCHAR2(10),
   JOB VARCHAR2(9),
   MGR NUMBER(4),
   HIREDATE DATE,
   SAL NUMBER(7, 2),
   COMM NUMBER(7, 2),
   DEPTNO NUMBER(2)
-- table of emp records
create or replace type emp_table_type as table of emp_scalar_type
-- pipelined function
create or replace function get_emp( p_deptno in number )
  return emp_table_type
  PIPELINED
  as
   TYPE EmpCurTyp IS REF CURSOR RETURN emp%ROWTYPE;
    emp_cv EmpCurTyp;
    l_rec  emp%rowtype;
  begin
    open emp_cv for select * from emp where deptno = p_deptno;
    loop
      fetch emp_cv into l_rec;
      exit when (emp_cv%notfound);
      pipe row( emp_scalar_type( l_rec.empno, LOWER(l_rec.ename),
          l_rec.job, l_rec.mgr, l_rec.hiredate, l_rec.sal, l_rec.comm, l_rec.deptno ) );
    end loop;
    return;
  end;
select * from table(get_emp(20))
