Cursor in EXECUTE IMMEDIATE

Question

How to use cursor in EXECUTE IMMEDIATE command.
i.e. I have a dynamic SELECT query where I will get huge records while using EXECUTE IMEDIATE command, which I want that to be in a cursor.
Can I do this ? If yes how ?

Hi, it works perferctly fine with me. Oracle version 10.2.0.4
SQL> --create table t as select * from user_objects; ----->>> My mistake, there is no owner column in the table user_objects
SQL> create table t as select * from all_objects;
Table created.
SQL> CREATE OR REPLACE PROCEDURE dynamic_table (
  2    table_name IN VARCHAR2,
  condition IN VARCHAR2 DEFAULT NULL) AS
  3    4    where_clause VARCHAR2(100) := ' WHERE ' || condition;
  5    v_table varchar2(30);
  6    type v_typet  is table of t%rowtype index by pls_integer;
  7    v_tableT v_typeT;
  8  BEGIN
  -- first make sure that the table actually exists; if not, raise an exception
  SELECT OBJECT_NAME INTO v_table FROM USER_OBJECTS
  9   10   11    where object_name = upper(table_name) and object_type = 'TABLE';
  if condition is null then where_clause := ' order by object_type'; end if;
12   13    execute immediate 'SELECT * from ' || v_table || where_clause  bulk collect into v_tablet;
14    for indx in 1..v_tablet.count loop
    dbms_output.put_line(v_tablet(indx).owner || ' ' || v_tablet(indx).status);
15   16    end loop;
17    EXCEPTION
18    when no_data_found then
19      dbms_output.put_line ('Invalid table: ' || table_name);
20  end;
21  /
Procedure created.
begin
  dynamic_table('T', '');
  --Enter the table name you want for the 1st parameter and the condition for the second parameter.
  --I think you just want to switch from tables where you want to select.
end;
