MOVE − position a cursor
MOVE [ direction { FROM | IN } ] cursorname
MOVE repositions a cursor without retrieving any data. MOVE works exactly like the FETCH command, except it only positions the cursor and does not return rows.
Refer to FETCH [fetch(7)] for details on syntax and usage.
On successful completion, a MOVE command returns a command tag of the form
MOVE count
The count is the number of rows that a FETCH command with the same parameters would have returned (possibly zero).
BEGIN WORK;
DECLARE liahona CURSOR FOR SELECT * FROM films;
-- Skip the
first 5 rows:
MOVE FORWARD 5 IN liahona;
MOVE 5
-- Fetch the
6th row from the cursor liahona:
FETCH 1 FROM liahona;
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 end the transaction:
CLOSE liahona;
COMMIT WORK;
There is no MOVE statement in the SQL standard.
CLOSE [close(7)], DECLARE [declare(l)], FETCH [fetch(l)]
