DESCRIPTION

db.copy allows the user to copy a table between two databases. Databases can be connected through different drivers (see example).

NOTES

Attribute tables can be copied manually using db.copy and v.db.connect. Current connection settings are saved in $LOCATION/vector_map/dbln.

EXAMPLES

DBF ->PG

Storing table 'markveggy.dbf' (in current directory) into PostgreSQL through ODBC:
db.copy from_driver=dbf from_database=$HOME/grassdata/spearfish60/user1/dbf \
   from_table=markveggy to_driver=pg to_database="host=pgserver,dbname=grass6test" to_table=markveggy 

PG -> DBF

db.copy from_driver=pg  from_database="host=pgserver.itc.it,dbname=testdb" 
  from_table=origtable to_driver=dbf to_database=$HOME/grassdata/spearfish60/user1/dbf to_table=origtable
