Hi,
I'm quite new in using Grass, so maybe this is not a very complicate error.
I'm trying to use *v.rast.stats* to calculate statistics on a vector
poligon from a raster map, but I always receive this error:
v.rast.stats vector=samo_calc_v@samoggia raster=dem80@samoggia
colprefix=elev
Updating the database ...
DBMI-DBF driver error:
ERROR: Errore durante l'esecuzione: 'BEGIN TRANSACTION'
The new columns were created but they're empty and the table of
attributes isn't corrupted.
Following the suggestion of a member of the Osgeo Team, I tried to
download this nc dataset
grass.osgeo.org/sampledata/north_carolina/nc_spm_latest.zip
<http://grass.osgeo.org/sampledata/north_carolina/nc_spm_latest.zip>
and I tried to do this, just to remove all doubt:
(Tue Jul 08 10:04:05 2014)
g.copy vect=zipcodes_wake,myzipcodes_wake
Copy vector <zipcodes_wake@PERMANENT> to current mapset as <myzipcodes_wake>

Updating the database ...
DBMI-DBF driver error:
ERROR: Errore durante l'esecuzione: 'BEGIN TRANSACTION'

The error remain.
I'm using Grass 6.4.4 on Windows 7, but if I make the same passages in
an other pc (always Windows 7, Grass 6.4.4), it works without problems.
Has anybody a suggestion about why does it happen and what to do?
All suggestions all welcome! Thanks!
Best regards,
Francesca
