# CLOSE

## Name

CLOSE -- close a cursor

## Synopsis

    CLOSE { name | ALL }

## 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.

## Parameters

`name`

  The name of an open cursor to close.

`ALL`

  Close all open cursors.

## Notes

PostgreSQL does not have an explicit `OPEN` cursor statement; a cursor is considered open when it is declared. Use the DECLARE statement to declare a cursor.

You can see all available cursors by querying the `pg_cursors` system view.

## Examples

Close the cursor `liahona`:

    CLOSE liahona;

## Compatibility

`CLOSE` is fully conforming with the SQL standard. `CLOSE ALL` is a PostgreSQL extension.
