<h2>DESCRIPTION</h2>

<em>v.db.dropcolumn</em> drops a column from the attribute table connected
to a given vector map. It automatically checks the connection for the specified
layer. <em>v.db.dropcolumn</em> omits to delete the 'cat' column which is
relevant to keep the connection between vector map and table.

<h2>NOTES</h2>

v.db.dropcolumn 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>EXAMPLES</h2>

Dropping a column:<br>
<div class="code"><pre>
v.db.dropcolumn sentiero_brenta_points column=slope
v.info -c sentiero_brenta_points
</pre></div>
