By using Ref cursor we can change the select statement
dynamically at runtime which is available in the cursor
definition based on some validation.For this we need to
define ref cursor type by using following syntax.

type <type_name> is ref cursor return <return_type>;

here <type_name> is the name of the ref cursor and
<return_type> will be the return type of ref cursor it may
be %type/%rowtype/record type/plsql table type/nested table
type/varray type.

if <return_type> is mentioned we will called it as strong
ref cursor.

if <return_type> is not mentioned we will called it as weak
ref cursor.

after this we need to define ref cursor variable by using
the following syntax.

v_variable_name ref_cursor_type_name;

then based on validations we can change the ref cursor
dynamically.

for example
------------------
declare
type ref_cur is ref cursor;
v_ref_cur ref_cur;
v_deptno emp.deptno%type;
begin
select deptno into v_deptno from emp where empno=7788;
if v_deptno=20 then
open v_ref_cur for select * from emp;
elsif v_deptno=30 then
open v_ref_cur for select * from dept;
else
open v_ref_cur for select * from salgrade;
end if;
end;
