SQL Server offers two scrolling option on cursors:

1. FORWARD_ONLY - The cursor can only be scrolled forward with "FETCH NEXT" statements. In another word, you can only loop through the cursor from the first row to the last row. FORWARD_ONLY is the default option.

2. SCROLL - The cursor can be scrolled back and forth with "FETCH NEXT", "FETCH PRIOR", and other fetch options.

The tutorial example below creates a cursor with the SCROLL option so that the result set can be looped through backward:

DECLARE @ggl_cursor CURSOR;

SET @ggl_cursor = CURSOR SCROLL FOR

SELECT id, url, notes, counts, time

FROM ggl_links ORDER BY id;

OPEN @ggl_cursor;

DECLARE @id INT, @url VARCHAR(80), @notes VARCHAR(80),

@counts INT, @time DATETIME;

FETCH LAST FROM @ggl_cursor INTO @id, @url, @notes,

@counts, @time;

WHILE @@FETCH_STATUS = 0 BEGIN

PRINT CONVERT(CHAR(5),ISNULL(@id,0))

+CONVERT(CHAR(18),ISNULL(@url,'NULL'))

+CONVERT(CHAR(20),ISNULL(@notes,'NULL'))

+CONVERT(CHAR(4),ISNULL(@counts,0))

+CONVERT(CHAR(11),ISNULL(@time,'2007'));

FETCH PRIOR FROM @ggl_cursor INTO @id, @url, @notes,

@counts, @time;

END

CLOSE @ggl_cursor;
