Bryan Pendleton commented on DERBY-3593:
----------------------------------------

Can you provide a complete standalone script that we can 
run to see this? I'm having a bit of trouble reproducing the problem.

Here's what I tried, and it worked for me (with the current trunk code):

create table "values" (indicador_id int, valor int);
insert into "values" values (1,1);
select v.indicador_id as col_1, 'someString' as col_2,
     sum(v.valor) as col_3
 from
     "values" v
 where v.valor is null and v.indicador_id = 13
 group by v.indicador_id
 having sum(v.valor) > 3 ;

COL_1      |COL_2     |COL_3
----------------------------------

> I got a error:
> Error: Column 'V.COL_1' is either not in any table in the FROM list or appears within a join specification and is outside the scope of the join specification or appears in a HAVING clause and is not in the GROUP BY list. If this is a CREATE or ALTER TABLE  statement then 'V.COL_1' is not a column in the target table.

> if i gave no name to the table 'VALUES' or remove the aliases 'col_1' and 'col_3' of the corresponding selected fields, the query runs ok. The alias for the constant column, 'col_2', don't affect the query.
> The query also runs ok if i remove the 'having' clause.
> Queries that work:
> ----------------------------------------------------------------------------
> select

> I think there's a problem when derby is trying to match the selected fields with the grouped ones, because 'V.COL_1', as it appears in the error message, doesn't exist in any place of my query. The correct would be 'V.indicador' or 'COL_1'.
