Hi,
Thank you for the help. The rule suggested by Micheal helped me to
achieve the result I was looking for.
> query!
> :SELECT! a:selection_list (WHERE! b:where_list )?
>
> {#query = #(#[QUERY, "QUERY"],
> #([SELECT, "SELECT"], a),
> #([WHERE, "WHERE"], b));
> ;
AST construction in the above rule does not evaluate the cases when
WHERE part is missing.

Vaida :)
