oracle中的WITH关键字，相当于是试图

WITH V_DOCID AS
 (
 SELECT b.doc_id id
    FROM tb_oa_doc_base b
    join tb_oa_doc_recv c
      on b.doc_id = c.doc_id
   where b.flow_status <> 0
     and ((c.sec_level = 4 and is_pub = 1) or
         b.doc_id in (select doc_id
                         from TB_OA_DOC_RECV_PER a
                        where 1=1
                          and a.is_readed = 1))
      or b.doc_id in (select w2.doc_id
                        from (select row_number() over(partition by w1.doc_id, w1.applay_id order by w1.doc_id, w1.applay_id) row_num,
                                     w1.doc_id,
                                     w1.applay_id
                                from (select t1.doc_id, t.applay_id
                                        from tb_wf_proc_log t

                       where w2.row_num = 1 )
                       )
   select  *   from   V_DOCID
