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 for details on syntax and usage.
Notes
MOVE is a PostgreSQL language extension.
Refer to FETCH for a description of valid arguments. Refer to DECLARE to define a cursor. Refer to BEGIN, COMMIT, and ROLLBACK 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
