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  [declare(7)]
       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.

EXAMPLES

       Close the cursor liahona:

       CLOSE liahona;

COMPATIBILITY

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