CLOSE(7)

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(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.
