Positions a cursor.
MOVE [ <forward_direction> [ FROM | IN ] ] <cursor_name>
where forward_direction can be empty or one of:
NEXT FIRST LAST ABSOLUTE <count> RELATIVE <count> <count> ALL FORWARD FORWARD <count> FORWARD ALL
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.
Note: You cannot
PARALLEL RETRIEVE CURSOR.
It is not possible to move a cursor position backwards in Greenplum Database, since scrollable cursors are not supported. You can only move a cursor forward in position using
On successful completion, a
MOVE command returns a command tag of the form
The count is the number of rows that a
FETCH command with the same parameters would have returned (possibly zero).
MOVEcommand are identical to those of the
FETCHcommand; refer to FETCH for details on syntax and usage.
-- Start the transaction:
-- Set up a cursor:
DECLARE mycursor CURSOR FOR SELECT * FROM films;
-- Move forward 5 rows in the cursor
MOVE FORWARD 5 IN mycursor; MOVE 5
-- Fetch the next row after that (row 6):
FETCH 1 FROM mycursor; code | title | did | date_prod | kind | len -------+--------+-----+------------+--------+------- P_303 | 48 Hrs | 103 | 1982-10-22 | Action | 01:37 (1 row)
-- Close the cursor and end the transaction:
CLOSE mycursor; COMMIT;
There is no
MOVE statement in the SQL standard.
