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.
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).
Examples
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;

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;
