MOVE
MOVE — position a cursor
Synopsis
MOVE [ direction [ FROM | IN ] ] cursor_name where direction can be empty or one of: NEXT PRIOR FIRST LAST ABSOLUTE count RELATIVE count count ALL FORWARD FORWARD count FORWARD ALL BACKWARD BACKWARD count BACKWARD ALL
Description
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.
The parameters for the MOVE
command are identical to those of the FETCH
command; refer to FETCH for details on syntax and usage.
Outputs
On successful completion, a MOVE
command returns a command tag of the form
MOVE count
The count
is the number of rows that a FETCH
command with the same parameters would have returned (possibly zero).
Examples
BEGIN WORK; DECLARE liahona CURSOR FOR SELECT * FROM films; -- Skip the first 5 rows: MOVE FORWARD 5 IN liahona; MOVE 5 -- Fetch the 6th row from the cursor liahona: FETCH 1 FROM liahona; 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 end the transaction: CLOSE liahona; COMMIT WORK;
Compatibility
There is no MOVE
statement in the SQL standard.
