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 the FETCH command for details on syntax and usage.

Notes
MOVE is a Postgres
language extension.
Refer to FETCH for a description
of valid arguments.
Refer to DECLARE to declare a cursor.
Refer to BEGIN WORK, COMMIT WORK,
ROLLBACK WORK statements
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;

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 place.
