CLOSE(7)						  PostgreSQL 9.2.7 Documentation						  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.

NAME

       MOVE - position a cursor on a specified row of a table

SYNOPSIS

       MOVE [ direction ] [ count ]
	   { IN | FROM } cursor

DESCRIPTION

       MOVE  allows  a	user to move cursor position a specified number of rows.  MOVE works like the FETCH command, but only positions the cursor
       and does not return rows.

       Refer to FETCH [fetch(7)] for details on syntax and usage.

   NOTES
       MOVE is a PostgreSQL language extension.

       Refer to FETCH [fetch(7)] for a description of valid arguments.	Refer to  DECLARE  [declare(7)]  to  define  a	cursor.   Refer  to  BEGIN
       [begin(7)], COMMIT [commit(7)], and ROLLBACK [rollback(7)] for further information about transactions.

USAGE

       Set up and use a cursor:

       BEGIN WORK;
       DECLARE liahona CURSOR  FOR SELECT * FROM films;
       -- Skip first 5 rows:
       MOVE FORWARD 5 IN liahona;
       MOVE
       -- Fetch 6th row in the cursor liahona:
       FETCH 1 IN liahona;
       FETCH

	code  | title  | did | date_prod | kind   | len
       -------+--------+-----+-----------+--------+-------
	P_303 | 48 Hrs | 103 | 1982-10-22| Action | 01:37
       (1 row)
       -- close the cursor liahona and commit work:
       CLOSE liahona;
       COMMIT WORK;

COMPATIBILITY

   SQL92
       There  is  no SQL92 MOVE statement.  Instead, SQL92 allows one to FETCH rows from an absolute cursor position, implicitly moving the cursor
       to the correct position.
