> For queries of the form:
> select id from parent inner join child on parent.id=child.parentid
> the SQL2 parser currently only returns a generic error message "This query result contains more than one selector". 
> The error message should point to the problematic token: 
> Query: select id(*)from parent inner join child on parent.id=child.parentid; expected: Need to specify the selector name for "id" because the query contains more than one selector.
