How to dump a query on a XLS file?

Question

I´m working in a stored procedure on that i can send a dinamic query and it return me the result into a xls file.
I´ve found the way to generate that xls file from Pl/sql, but now I need be able to assing each field of each row into his corresponding cell. For this I need to put each field of each row in a variable and then work on it.
For generate xls file, I´ve created a datatype by following the indications of Jasson Bennet´s blog.
http://radio-weblogs.com/0137094/2006/10/26.html
In the example, values are assigned directly to the cells. But it not is valid for me because I dont know what will be these...
I think that if you want see the blog, you´ll can understand better what I´m refering...
Thanks for your time...

Answer 1

Strange requirement, you don't know the query, the columns and the number of rows you get, but you know that you want the value of the second column of the second row :)
But try this
declare
  t_c integer;
  t_r integer;
  t_v varchar2(100);
begin
  t_c := dbms_sql.open_cursor;
  dbms_sql.parse( t_c, q''select 'Roy' name, 'sales' deptno, 25 age from dual
union all select 'Sara', 'HHRR', 30 from dual
union all select 'Mike', 'finances', 35 from dual'', dbms_sql.native );
  dbms_sql.define_column( t_c, 2, t_v, 100 );
  t_r := dbms_sql.execute( t_c );
  t_r := dbms_sql.fetch_rows( t_c );
  t_r := dbms_sql.fetch_rows( t_c );
  dbms_sql.column_value( t_c, 2, t_v );
  dbms_sql.close_cursor( t_c );
  dbms_output.put_line( t_v );
end;
