If we want to return multiple row from a function then we can use ref cursor
function .Example is given below:

create or replace function f1 return sys_refcursor as
r1 sys_refcursor;
begin open r1 for select * from emp;
return(r1);
end;
call the
function as :select f1 from
dual; then it returns :

This can be done by a function called TABLE FUNCTION
by means of this you can return more number of rows and columns this is more effective than using ref cursor
