move(7l)

position a cursor on a specified row of a table

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(l)] for details on syntax and usage.

NOTES

MOVE is a PostgreSQL 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.
