<h3>Berkeley DB Reference Guide: Access Methods</h3>
<p>
<h1 align=center>Deleting records</h1>
<p>
The <a href="../../api_c/Db/del.html">DB->del</a> function is the standard function for retrieving
records from the database. In general, the delete function takes a
key and deletes the data item associated with it from the database.
<p>
If the database has been configured to support duplicate records, the
<a href="../../api_c/Db/del.html">DB->del</a> function will remove <b>all</b> of the duplicate records.
To remove individual duplicate records, you must use a Berkeley DB cursor
interface.
