<p>The <a href="../api_reference/C/dbdel.html" class="olink">DB->del()</a> method deletes records from the database. In general,
|
||
<a href="../api_reference/C/dbdel.html" class="olink">DB->del()</a> takes a key and deletes the data item associated with
|
||
it from the database.</p>
|
||
<p>If the database has been configured to support duplicate records, the
|
||
<a href="../api_reference/C/dbdel.html" class="olink">DB->del()</a> method will remove all of the duplicate records. To remove
|
||
individual duplicate records, you must use a Berkeley DB cursor interface.</p>
