Description
MOVE allows the user to move the cursor position a
specified number of rows, or all the way to the end or start of the query.
MOVE works exactly like the FETCH
command, except it only repositions the cursor and does not return rows.

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 position.
