| title: CLOSE |
| --- |
| |
| Closes a cursor. |
| |
| ## <a id="topic1__section2"></a>Synopsis |
| |
| ``` pre |
| CLOSE <cursor_name> |
| |
| ``` |
| |
| ## <a id="topic1__section3"></a>Description |
| |
| `CLOSE` frees the resources associated with an open cursor. After the cursor is closed, no subsequent operations are allowed on it. A cursor should be closed when it is no longer needed. |
| |
| Every non-holdable open cursor is implicitly closed when a transaction is terminated by `COMMIT` or `ROLLBACK`. A holdable cursor is implicitly closed if the transaction that created it aborts via `ROLLBACK`. If the creating transaction successfully commits, the holdable cursor remains open until an explicit `CLOSE` is executed, or the client disconnects. |
| |
| ## <a id="topic1__section4"></a>Parameters |
| |
| <dt> \<cursor\_name\> </dt> |
| <dd>The name of an open cursor to close.</dd> |
| |
| ## <a id="topic1__section5"></a>Notes |
| |
| HAWQ does not have an explicit `OPEN` cursor statement. A cursor is considered open when it is declared. Use the `DECLARE` statement to declare (and open) a cursor. |
| |
| You can see all available cursors by querying the `pg_cursors` system view. |
| |
| ## <a id="topic1__section6"></a>Examples |
| |
| Close the cursor `portala`: |
| |
| ``` pre |
| CLOSE portala; |
| ``` |
| |
| ## <a id="topic1__section7"></a>Compatibility |
| |
| `CLOSE` is fully conforming with the SQL standard. |
