NAME

db.copy

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
