| 32 | * <P> | ||
| 33 | * Warnings may be retrieved from <code>Connection</code>, <code>Statement</code>, | ||
| 34 | * and <code>ResultSet</code> objects. Trying to retrieve a warning on a | ||

| 36 | * Similarly, trying to retrieve a warning on a statement after it has been | ||
| 37 | * closed or on a result set after it has been closed will cause | ||
| 38 | * an exception to be thrown. Note that closing a statement also | ||
| 39 | * closes a result set that it might have produced. | ||
