Hi
For this you might require to see
"Expanding Hierarchies" in BOL

here is the example

CREATE PROCEDURE expand (@current char(20)) as
SET NOCOUNT ON
DECLARE @level int, @line char(20)
CREATE TABLE #stack (item char(20), level int)
INSERT INTO #stack VALUES (@current, 1)
SELECT @level = 1

WHILE @level > 0
BEGIN
IF EXISTS (SELECT * FROM #stack WHERE level = @level)
BEGIN
SELECT @current = item
FROM #stack
WHERE level = @level
SELECT @line = space(@level - 1) + @current
PRINT @line
DELETE FROM #stack
WHERE level = @level
AND item = @current
INSERT #stack
SELECT child, @level + 1
FROM hierarchy
WHERE parent = @current
IF @@ROWCOUNT > 0
SELECT @level = @level + 1
END
ELSE
SELECT @level = @level - 1
END -- WHILE

Please let me know if it solves the purpose..


best Regards,
Chandra
