To delete a record using a cursor, simply position the cursor to the
record that you want to delete and then call
<span>
<span><code class="methodname">DBC->del()</code>.</span>
</span>
</p>
<p>For example:</p>
<a id="c_cursor8"></a>
<pre class="programlisting">#include <db.h>
#include <string.h>
...
DB *dbp;
DBC *cursorp;
DBT key, data;
char *key1str = "My first string";
int ret;
/* Database open omitted */
/* Initialize our DBTs. */
memset(&key, 0, sizeof(DBT));
memset(&data, 0, sizeof(DBT));
/* Set up our DBTs */
key.data = key1str;
key.size = strlen(key1str) + 1;
/* Get the cursor */
dbp->cursor(dbp, NULL, &cursorp, 0);
/* Iterate over the database, deleting each record in turn. */
while ((ret = cursorp->get(cursorp, &key,
&data, DB_SET)) == 0) {
cursorp->del(cursorp, 0);
}
/* Cursors must be closed */
if (cursorp != NULL)
cursorp->close(cursorp);
if (dbp != NULL)
dbp->close(dbp, 0);</pre>
