sql server 2005中使用with实现递归的方法（sql server 2005使用教程）深度揭秘

WITH fw_requestion_note_temp(old_apply_id) AS ( –取根节点放入临时表

SELECT old_apply_id FROM fw_requestion_note –WHERE old_apply_id=’e741470e-8b5c-4f91-9b03-c7474d103aef’

–根据已取到的数据递归取其字节点的数据

 UNION ALL SELECT fw.old_apply_id FROM fw_requestion_note fw

 INNER JOIN fw_requestion_note_temp temp ON fw.apply_id=temp.old_apply_id ) SELECT old_apply_id FROM fw_requestion_note_temp
