> There was a bug in the SemanticAnalyzer that adds the columnID for one more time for "*".
> This causes queries like this to fail:
> {code}
> create table zshao_lazy (a int);
> // load one row of data into zshao_lazy
> select * from (select *, a as a2 from zshao_lazy) z order by a2 limit 10;
> {code}
> The query will fail at execution time.
