CLOSE — close a cursor
name| ALL }
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
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.
The name of an open cursor to close.
Close all open cursors.
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.
If a cursor is closed after a savepoint which is later rolled back, the
CLOSE is not rolled back; that is, the cursor remains closed.
Close the cursor
CLOSE is fully conforming with the SQL standard.
CLOSE ALL is a PostgreSQL extension.
