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.

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.
