A DbException object contains an informational string and an errno. The errno can be obtained using <a href="../api_java/get_errno.html">DbException.get_errno</a>. Since DbException inherits from the java.Exception, the string portion is available using toString(). <p>Some methods may return non-zero values without issuing an exception. This occurs in situations that are not normally considered an error, but when some informational status is returned. For example, <a href="../api_java/db_get.html">Db.get</a> returns DB_NOTFOUND when a requested key does not appear in the database. <h3>Class</h3> <a href="../api_java/except_class.html">DbException</a> <h1>See Also</h1> <a href="../api_java/get_errno.html">DbException.get_errno</a>, <a href="../api_java/deadlock_class.html">DbDeadlockException</a>, <a href="../api_java/mem_class.html">DbMemoryException</a> and <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>. </tt> <table><tr><td><br></td><td width="1%"> <a href="../api_java/java_index.html"><img src="../images/api.gif" alt="API"></a><a href="../ref/toc.html"><img src="../images/ref.gif" alt="Ref"></a> </td></tr></table> <p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> </body> </html>
