Declare
type empno_arr is varray(100) of emp.empno%type;
empno_arry empno_arr:=empno_arr();
c_empno emp.empno%type;
counter number(10);
begin
select count(*) into counter from emp;
select empno into c_empno
          from emp 
           where empno =7369;
empno_arry.extend(10);--Need to provide the  length of extend array. Otherwise it will consider as  index 1
empno_arry(10):=c_empno; -- array is trying to assigning the value of uninitialized position 10.
end;
