Subject: v.extract, v.overlay and database connection

I have a vector map with a database connected, but when I do a query by 
atributes (v.extract) I loose this connection, I obtain a vectorial without 
database, and I want a new data base (smaller) for this new vectorial map, 
it is possible? I have tried to do v.db.connect after, I have tried also to 
do the connection in the internal files but without success...

With v.overlay I obtain a new data base (dbf) for the new map, but this dbf 
file do not have all the data (fields) of the original dbf... how can I 
obtain the same dbf table but only for the new vector map?

Thank you

The 'new' option is < 0? The table is created only for new=-1.

You have probably old version of GRASS 5.7, try something > Fri Dec 3

I put -1 for NEW, but I don't obtain the dbf table... when I do a query
with mouse, for instance, in this new vector map I obtain this:


368180.14731586(E) 4611931.60424469(N)

explocastell4 in explocastell  Centroid
field: 1
category: 1126
Database connection not defined


The category 1126 is from the original dbf table, but I need a table with
all the fields of the original table it is not posible? may I do a
connection? I have tried but without success...

Thank you very much,

Lourdes

I can't reproduce this error. The user hasn't replied. Thus closing it.
