execute immediate

hi,

I built a dynamic query in PL/SQL
when I did

> spool test.sql
> ...
> stmt := select col1,col1.. from ...
> dbms_output.put_line(stmt);
> @test.sql

the result is OK

When I did
> execute immediate stmt ;

nothing on the screen

obviously I misuse execute immediate
can you help me please ?
