<h3>Description(db truncate)</h3>
<p>Empties the database, discarding all records it contains.</p>
<p>The options are as follows:</p>
<dl compact>
<dt>-auto_commit<dd>Enclose the call within a transaction. If the call succeeds, changes
made by the operation will be recoverable. If the call fails, the
operation will have made no changes.
<dt>-txn txnid<dd>If the operation is to be
transaction-protected (other than by specifying the -auto_commit flag),
the <b>txnid</b> parameter is a transaction handle returned from
<i>env</i> <b>txn</b>.
</dl>
<p>The <i>db</i> <b>truncate</b> command returns the number of records discarded
from the database on success.</p>
<p>In the case of error, a Tcl error is thrown.</p>
