If the <b>-f</b> force flag is not given then nothing is removed. <h2>NOTES</h2> <em>v.db.droptable</em> is a front-end to <em>db.execute</em> to allow easier usage. The existing database connection(s) can be verified with <em>v.db.connect</em>. <h2>EXAMPLE</h2> Removing attribute table connected to layer 2:<br> <div class="code"><pre> v.db.droptable sentiero_brenta_points layer=2 v.db.connect -p sentiero_brenta_points </pre></div> <h2>SEE ALSO</h2> <em><a HREF="db.execute.html">db.execute</a></em>, <em><a HREF="v.db.addcol.html">v.db.addcol</a></em>, <em><a HREF="v.db.addtable.html">v.db.addtable</a></em>, <em><a HREF="v.db.connect.html">v.db.connect</a></em>, <em><a HREF="v.db.dropcol.html">v.db.dropcol</a></em>, <em><a HREF="v.db.select.html">v.db.select</a></em>, <em><a HREF="v.db.update.html">v.db.update</a></em> <h2>AUTHOR</h2> Markus Neteler <p><i>Last changed: $Date: 2007-05-09 22:10:56 +0200 (Wed, 09 May 2007) $</i> <HR> <P><a href="index.html">Main index</a> - <a href="vector.html">vector index</a> - <a href="full_index.html">Full index</a></P> <P>© 2003-2008 <a href="http://grass.osgeo.org">GRASS Development Team</a></p> </body> </html>
