<h3>Description(db get_join)</h3>
<p>The <i>db</i> <b>get_join</b> command performs the cursor operations required to
join the specified keys and returns a list of joined {key data} pairs.
See <a href="../../db4-devel-4.3.29/ref/am/join.html">Equality join</a> for more information on
the underlying requirements for joining.</p>
<p>The options are as follows:</p>
<dl compact>
<dt>-txn txnid<dd>If the operation is to be
transaction-protected,
the <b>txnid</b> parameter is a transaction handle returned from
<i>env</i> <b>txn</b>.
</dl>
<p>In the case of error, a Tcl error is thrown.</p>
