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.

       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.
