MOVE(7) SQL Commands MOVE(7)
NAME
MOVE - position a cursor on a specified row of a table
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(7)] for details on syntax and usage.
NOTES
MOVE is a PostgreSQL language extension.
Refer to FETCH [fetch(7)] for a description of valid arguments. Refer to DECLARE [declare(7)] to define a cursor. Refer to BEGIN
[begin(7)], COMMIT [commit(7)], and ROLLBACK [rollback(7)] 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.
