<h2>DESCRIPTION</h2>

<em>db.droptable</em> drops an attribute table.  If the <b>-f</b>
force flag is not given then nothing is removed, instead a preview of
the action to be taken is printed.

<h2>NOTES</h2>

<em>db.droptable</em> is a front-end
to <em><a href="db.execute.html">db.execute</a></em> to allow easier
usage. To some extent it is verified if the table is connected to a
vector map to avoid accidental table removal.

<h2>EXAMPLES</h2>

<h3>Removing an attribute table from default database</h3>

<div class="code"><pre>
# show default database
db.connect -p

# show available tables
db.tables -p

# this will show what would happen
db.droptable table=sometable

# actually drop the table
db.droptable -f table=sometable
</pre></div>

<h3>Removing an attribute table from given database</h3>

<em>db.droptable</em> allows defining optionally <b>driver</b>
and <b>database</b> options different from default connection settings
(<code>db.connect -p</code>).

<div class="code"><pre>
# drop the table from SQLite database
db.droptable -f table=sometable driver=sqlite database=/opt/sqlite.db
</pre></div>
