<h2>DESCRIPTION</h2>

<em>db.in.ogr</em> imports attribute tables in various formats as
supported by the <a href="http://gdal.org/ogr">OGR library</a> on the local system (DBF, CSV, PostgreSQL,
SQLite, MySQL, ODBC, etc.). Optionally a unique <b>key</b> (ID) column can be
added to the table.

<h2>EXAMPLES</h2>

<h3>Import CSV file</h3>

Limited type recognition can be done for Integer, Real, String, Date, Time and DateTime
columns through a descriptive file with same name as the CSV file, but .csvt extension
(see details <a href="http://www.gdal.org/ogr/drv_csv.html">here</a>).

<div class="code"><pre>
# NOTE: create koeppen_gridcode.csvt first for type recognition
db.in.ogr dsn=koeppen_gridcode.csv output=koeppen_gridcode
db.select koeppen_gridcode
</pre></div>

<h3>Import DBF table</h3>

Import of a DBF table with additional unique key column (e.g., needed
for <em><a href="v.in.db.html">v.in.db</a></em>).

<div class="code"><pre>
db.in.ogr dsn=/path/to/mydata.dbf output=census_raleigh key=myid
db.describe -c census_raleigh
</pre></div>

<h3>Import of a SQLite table</h3>

<div class="code"><pre>
db.in.ogr dsn=/path/to/sqlite.db db_table=census_raleigh output=census_raleigh
</pre></div>

<h3>Import of a PostgreSQL table</h3>

<div class="code"><pre>
db.in.ogr dsn="PG:host=localhost dbname=ecad user=neteler" \
          db_table=ecad_verona_tmean output=ecad_verona_tmean
db.select ecad_verona_tmean
db.describe -c ecad_verona_tmean
</pre></div>

<h3>Import XLS file</h3>

To force reading headers, define environmental
variable <tt>OGR_XLS_HEADERS='FORCE'</tt>. Parameter <b>db_table</b>
refers to the list within XLS file.

<div class="code"><pre>
export OGR_XLS_HEADERS='FORCE'
db.in.ogr dsn=address.xls db_table=address_data
</pre></div>
