How to fetch the Rowid with all the columns of a table using bulk collect for a cursor in oracle

declare
    cursor c_1 is select a.*, a.rowid from an_test a;

    type t_1 is table of an_test%rowtype;

    type l_row_id is table of UROWID;

    tab t_1; 

    row l_row_id;

begin
    open c_1;

    loop
        fetch c_1 bulk collect into tab, row limit 1000;
        ...
    end loop;
end;

I am trying to execute the above code but it is giving me the error like :

PLS-00597: expression 'tab' in the INTO list is of wrong type.

Is there any other/alternate way to do like this?

Thanks in advance.

If you can manage with the rowid in the same record, base your type on the cursor instead of the table:

declare
    cursor c is
        select a.*, a.rowid
        from   customer a;

    type t is table of c%rowtype;
    tab t;

begin
    open c;
    fetch c bulk collect into tab limit 1000;
end;
