From DBF to PostgreSQL

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

From PostgreSQL to DBF

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

From PostgreSQL to PostgreSQL with condition

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"

From DBF to SQLite

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
