KEYWORDS
database, export, attribute table
SYNOPSIS
db.out.ogr
db.out.ogr --help
db.out.ogr input=name output=name [layer=string] format=string [table=name]
[--overwrite] [--help] [--verbose] [--quiet] [--ui]
Flags:
--overwrite
Allow output files to overwrite existing files
--help
Print usage summary
--verbose
Verbose module output
--quiet
Quiet module output
--ui
Force launching GUI dialog
Parameters:
input=name [required]
GRASS table name
Or data source for direct OGR access
output=name [required]
Output table file name or DB connection string
layer=string
Layer number or name
Vector features can have category values in different layers. This number determines
which layer to use. When used with direct OGR access this is the layer name.
Default: 1
format=string [required]
Table format
Options: CSV, DBF, GML, MySQL, PostgreSQL, SQLite
Default: CSV
table=name
Name for output table (default: input name)
DESCRIPTION
db.out.ogr exports GRASS GIS attribute tables into various formats as supported by the OGR
driver on the local system (CSV, DBF, PostgreSQL, SQLite, MySQL, ODBC, etc.).
The output parameter is used to define the output file name (if the path is not defined,
the module will attempt to write to the current directory). In case of a database
connection as output, the connection string has to be specified.
The layer parameter is needed if the attribute table to be exported is linked as
non-default layer to a vector map.
EXAMPLES
Export of GRASS GIS attribute table to a CSV table file (default format)
db.out.ogr input=precip_30ynormals output=precip_30ynormals.csv
Export of a GRASS GIS attribute table to a DBF table
db.out.ogr input=precip_30ynormals output=precip_30ynormals.dbf format=DBF
Export of GRASS GIS attribute table into a PostgreSQL table
db.out.ogr input=precip_30ynormals \
output="PG:host=localhost dbname=meteo user=neteler" \
format=PostgreSQL
# verify
echo "SELECT * FROM precip_30ynormals" | psql meteo
