How to convert the varray to ref cursor

Question

Hi,
Is there any way to convert varray to ref cursor....
i dont want to use any table or record as an ref cursor..
i just want to create a procedure which returns a ref cursor..
below is the sample procedure for it..
create or replace procedure FETCH_DATA1
tab_name in varchar2,
p_recordset1 OUT fetch_data_pak.ref_cursor
AS
type v_array1 is varray(1000) of t_transaction%rowtype;
v_array2 v_array1;
cursor s1 is select * from t_transaction where lastupdate_date > '08-Aug-09';
begin
open s1;
fetch s1 bulk collect into v_array2 limit 100;
close s1;
select * from table(cast (v_array2 as p_recordset1));
end FETCH_DATA1;
I need to convert the varray to ref cursor.....

Answer 1

Why put it into a varray at all?
You can just open the ref cursor for that select you are desiring.
And if you need to limit it to returning just the first 100 (as your code seems to imply), wrap it and filter on rownum.
Something similar to this:
create or replace procedure FETCH_DATA1
  tab_name in varchar2,
  p_recordset1 OUT fetch_data_pak.ref_cursor
AS
begin
  open p_recordset1 for
  select /*+ first_rows(100) */ * from (
    select * from t_transaction
    where lastupdate_date > to_date('08-08-2009','DD-MM-YYYY')
    --order by something
  where rownum <= 100;
end FETCH_DATA1;And note, that you really should have an order by when you wish to limit yourself to "first 100 rows" - otherwise it will be "random 100 rows".
That goes for your cursor solution as well...

Added explicit date conversion - it is bad practice not to explicitly convert dates ;-)
