Parameters:

from_driver=string: Input driver name; Options: ogr,sqlite,mysql,pg,odbc,dbf; Default: dbf
from_database=string: Input database name; Default: $GISDBASE/$LOCATION_NAME/$MAPSET/dbf/
from_table=string: Input table name (only, if 'select' is not used)
to_driver=string: Output driver name; Options: ogr,sqlite,mysql,pg,odbc,dbf; Default: dbf
to_database=string: Output database name; Default: $GISDBASE/$LOCATION_NAME/$MAPSET/dbf/
to_table=string: Output table name
where=string: Optional where condition (without WHERE key word), e.g.:
obec = 'Liptakov'
select=string: Full select statement (only, if 'from_table' and 'where' is not used), e.g.:

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

PG -> PG with condition

db.copy from_driver=pg  from_database="host=localhost,dbname=meteo" \
  from_table=ukraine to_driver=pg to_database="host=localhost,dbname=meteo" \
  to_table=selection where="cat < 500"

DBF -> SQLite

db.copy from_driver=dbf from_database=$HOME/grassdata/spearfish60/user1/dbf \
   from_table=ammprv to_driver=sqlite \
   to_database=$HOME/grassdata/spearfish60/user1/mysqlite.db to_table=ammprv

# convenient viewer:
sqlitebrowser $HOME/grassdata/spearfish60/user1/mysqlite.db

SQLite -> DBF

db.copy from_driver=sqlite from_database=$HOME/grassdata/spearfish60/user1/mysqlite.db \
   from_table=ammprv to_driver=dbf to_database=$HOME/grassdata/spearfish60/user1/dbf \
   to_table=ammprv
