## NAME

db.out.ogr - Exports attribute tables into various formats.

## KEYWORDS

database, export, output, 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
