Hi,
After the new command db.login and the remotion of v.database I have some
problem with the relocation of the table when I import vectors (like shapes)
in GRASS.

Grass put the table in the database setted in the options GV_* of file VAR
placed in the working mapset.

I see that the command db.connect change the DB_* options but not the GV_*
options.

How can I change the GV_* options and what about the function of the DB_*
options?

Thanks of all
Leonardo

About overwrite protection I think that it is very important to have a flag
to avoid delete the tables linked to a vector when I delete the vector. What
do you think about it?
Bye

GV_* are not used, vector tables are stored in database defined by DB_* (db.connect).

About overwrite protection I think that it is very important to have a flag
to avoid delete the tables linked to a vector when I delete the vector. What
do you think about it?

Almost impossible to add this flag to all modules. Why do you need that?
Cannot you db.copy the table?

AFAIK this was simplified recently:

2004-11-25 16:43 radim
        * Vlib/field.c: GV_ -> DB_

http://grass.itc.it/pipermail/grass-commit/2004-November/015859.html

As far as I understand the change, the GV_ stuff no longer exists as
DB connections are maintained now only by db.* tools (as v.database was
removed to simplify user's life).

So the VAR file should only contain DB_ lines (maybe a simple search/replace
helps).
