Ok no problem I musunderstand all, because I get confused at the moment of
that commentary, you're right.

As I have told you, this was a bug introduced earlier.

Ok a legacy error from the very first beta versions ;) but now is solve.
Thanks Ashesh.

By the way Ashesh as I notice you know the tool I'm going to make you some

I have been thinking a way of adding the group by and having operators to
the GQB to basically allow the user to create more complex queries, but I'm
not sure about the correct user interface to do this task, I think that
group by can be as the ordering tab and the having tab can be as the
criteria tab. Do you have any suggestions?

And about the join panel as I told you I was thinking that if the user
select one join should be an easy option to change the query type like a
floating toolbar with button with the join types that will be show near the
selected join. What do you think about this?

Now I publish a list of what I think will be useful functionalities on the
GQB if someone desiree to contribute:
1. Add Subqueries, this probably requeries multiples tabs for query.
2. Add Support to composite types.
3. Add a new skin for the graphics probably with a scroll on right and
showing always all the columns (fixed at top) but the other columns can be
move up/down with the scrollbar (an option can allow to choose between this
and old graphics). And each table have a minimize (shrink only to table
title),restore and remove from query button just as a window in a graphical
operative system.
4. Add Save/Load functionality (probably xml).

Sorry for a lot of commentaries for just one email.

Finally I tested your patch and everything was fine for me.

Regards, Luis.
