Are the search functions on the user and developer mailing lists working properly? I am looking for tips on adding attributes (something like add columns) to existing vector maps (I thought this was a job for v.digit) however, I keep getting the dreaded "no matching articles" returned.

I thing, that results from google are often better, then from the site search
for adding columns to the table see manual of db.execute
echo "alter table vector_file add column column_name varchar(50)"|db.execute

Yes, I think so:
http://grass.itc.it/searchgrass.php
Search: attributes
Restrict to: GRASS Developers Mailing list
-> Documents 1 - 10 of 835 matches.
Where did you try (URL?). It should be redirected to grass.itc.it.

Search for 'db.execute' 
http://grass.itc.it/grass60/manuals/html60_user/db.execute.html
Add new column to attribute table:
echo "ALTER TABLE roads ADD COLUMN length double" | db.execute
Hope this helps

Oh, really? If so, how to improve the situation (I am no htdig expert)?
Suggestions more than welcome.

Thanks Markus. I was going in through the community link, to mailing lists, then getting directed to:
http://grass.institutoecos.org.br/cgi-bin/htsearch
They seem to have some kind of server issue. I emailed the administrator about it.

Well, the idea of the implementation is that
requests are redirected to grass.itc.it (as htdig lives there).
I see the problem now when entering
http://grass.institutoecos.org.br/cgi-bin/htsearch
but how did you get there?

>but how did you get there?I pull up the GRASS site at:
http://grass.itc.it/then click the link to Community, which directs my browser to:
http://grass.itc.it/community/index.phpfrom there I go to Mailing lists, which takes me to:
http://grass.itc.it/community/support.php
So far fine.
From there, I clicked on the links 'GRASS user list archive (June
1996-today) under Archives, which directs to:
http://grass.institutoecos.org.br/grass-list/or
Archives mirror, which directs to
http://news.gmane.org/gmane.comp.gis.grass.userneither of which appear to be in working order.
Now I understand.
Suggestions
- "Full GRASS user list archive (1991-today)"
http://grass.itc.it/pipermail/grassuser/
is the *full* archive (the only one [1])
- above the table there is "Search these mailing lists"
http://grass.itc.it/searchgrass.php
Ok, I have restructured the table:
http://grass.itc.it/community/support.php
Please try again... (the grass.institutoecos.org.br I cannot solve,
but you can use our search engine).
Cheers
Markus
[1] Time ago I have added all mails from the original CERL
mailing lists and usenet period to our archive (except for spam)

The first user mail came from Italy then (hey!).

Thanks!
How about removing a column or changing a column name? I've tried:
> echo "ALTER TABLE table_name DROP COLUMN column_name double" | db.execute
and
> echo "ALTER TABLE table_name CHANGE COLUMN old_column_name new_column_name double" | db.execute
with no success...

As others noted, use db.execute.
v.digit will let you specify & create a new table but not alter an
existing one. I think this could be changed but that's the way it is
now.

In QGIS there is "Add column" button.
