db.copy allows the user to copy a table between two databases. Databases can be connected through different drivers (see examples below).
Attribute tables can be copied using db.copy and, when to be associated to a vector map, assigned to the map with v.db.connect. Current connection settings are saved in the file $LOCATION/vector_map/dbln.
Storing table ’geonames.dbf’ (in current
directory) into PostgreSQL through ODBC:
db.copy from_driver=dbf from_database=’$GISDBASE/$LOCATION_NAME/PERMANENT/dbf’ \
from_table=geonames to_driver=pg to_database="host=pgserver,dbname=testdb" \
to_table=geonames
db.copy from_driver=pg from_database="host=pgserver.example.org,dbname=testdb" \
from_table=origtable to_driver=dbf \
to_database=’$GISDBASE/$LOCATION_NAME/$MAPSET/dbf’ to_table=origtable
db.copy from_driver=pg from_database="host=localhost,dbname=testdb" \
from_table=geonames to_driver=pg to_database="host=localhost,dbname=testdb" \
to_table=selection where="cat < 500"
db.copy from_driver=dbf from_database=’$GISDBASE/$LOCATION_NAME/PERMANENT/dbf’ \
from_table=geonames_features to_driver=sqlite \
to_database=’$GISDBASE/$LOCATION_NAME/$MAPSET/sqlite/sqlite.db’ to_table=geonames_features # convenient viewer: sqlitebrowser $HOME/grassdata/nc_spm_08/user1/sqlite/sqlite.db
db.copy from_driver=sqlite from_database=’$GISDBASE/$LOCATION_NAME/$MAPSET/sqlite/sqlite.db’ \
from_table=ammprv to_driver=dbf to_database=’$GISDBASE/$LOCATION_NAME/$MAPSET/dbf/’ \
