<p>
In previous releases, the C++ <a href="../api_reference/CXX/dbdel.html" class="olink">Db::del</a> and
Java <code class="classname">Db.delete()</code> methods threw exceptions encapsulating the
<a class="link" href="program_errorret.html#program_errorret.DB_KEYEMPTY">DB_KEYEMPTY</a> error in some
cases when called on Queue and Recno databases. Unfortunately, this was undocumented
behavior.
</p>
<p>
For consistency with the other Berkeley DB methods that handle
<a class="link" href="program_errorret.html#program_errorret.DB_KEYEMPTY">DB_KEYEMPTY</a>,
this is no longer the case. Applications calling the
<a href="../api_reference/CXX/dbdel.html" class="olink">Db::del</a> and Java
<code class="classname">Db.delete()</code> methods on Queue or Recno databases, and
handling the
<a class="link" href="program_errorret.html#program_errorret.DB_KEYEMPTY">DB_KEYEMPTY</a> exception specially,
should be modified to check for a return value of
<a class="link" href="program_errorret.html#program_errorret.DB_KEYEMPTY">DB_KEYEMPTY</a> instead.
