[antlr-interest] Re: error in my rule...

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.

Regards,

Vaida :)
