To delete a record using a cursor, simply position the cursor to the
record that you want to delete and then call
</p>
<p>For example:</p>
<a id="java_cursor8"></a>
<pre class="programlisting">package db.GettingStarted;
import com.sleepycat.db.Cursor;
import com.sleepycat.db.Database;
import com.sleepycat.db.DatabaseEntry;
import com.sleepycat.db.LockMode;
import com.sleepycat.db.OperationStatus;
...
Cursor cursor = null;
Database myDatabase = null;
try {
...
// Database open omitted for brevity
...
// Create DatabaseEntry objects
// searchKey is some String.
DatabaseEntry theKey = new DatabaseEntry(searchKey.getBytes("UTF-8"));
DatabaseEntry theData = new DatabaseEntry();
// Open a cursor using a database handle
cursor = myDatabase.openCursor(null, null);
// Position the cursor. Ignoring the return value for clarity
OperationStatus retVal = cursor.getSearchKey(theKey, theData,
LockMode.DEFAULT);
// Count the number of records using the given key. If there is only
// one, delete that record.
if (cursor.count() == 1) {
System.out.println("Deleting " +
new String(theKey.getData(), "UTF-8") +
"|" +
new String(theData.getData(), "UTF-8"));
cursor.delete();
}
} catch (Exception e) {
// Exception handling goes here
} finally {
// Make sure to close the cursor
cursor.close();
}</pre>
