MOVE() SQL Commands MOVE()NAME
MOVE - Moves cursor position
SYNOPSIS
MOVE [ direction ] [ count ]
{ IN | FROM } cursor
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 [fetch(l)] for details on syntax and usage.
NOTES
MOVE is a Postgres language extension.
Refer to FETCH [fetch(l)] for a description of valid arguments. Refer
to DECLARE [declare(l)] to define a cursor. Refer to BEGIN [begin(l)],
COMMIT [commit(l)], and ROLLBACK [rollback(l)] 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;
COMPATIBILITY
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.
