Oracle 分页查询的一个实例

1.分页模板

select * from ( select rownum as rn , a.* from( 某个表名) a) where rn between 0 and 6

2 某个表名

select aa.title,aa.url,bb.times, bb.makedate from menu aa,
(select count(*) times,title , max(id) id,max(makedate) makedate from menulog group by title order by count(*) desc ) bb where aa.id=bb.id

3 将2 放入到1 中

select * from ( select rownum as rn , a.* from( select aa.title,aa.url,bb.times, bb.makedate from menu aa,
(select count(*) times,title , max(id) id,max(makedate) makedate from menulog group by title order by count(*) desc ) bb where aa.id=bb.id) a) where rn between 0 and 6

 

②另外一个实例

 

select aa.title,aa.url,bb.times, bb.makedate,cc.title from menu aa,menu cc, (select count(*) times,title , max(id) id,max(makedate) makedate from menulog group by title order by count(*) desc ) bb where aa.id=bb.id and aa.pid =cc.id and aa.title like '%医疗账单录入清单%'

select aa.title, aa.url, bb.times, bb.makedate, cc.title
  from menu aa,
       menu cc,
       (select count(*) times, title, max(id) id, max(makedate) makedate
          from menulog
         group by title
         order by count(*) desc) bb
 where aa.id = bb.id
   and aa.pid = cc.id
   and aa.title like '%医疗账单录入清单%'

 

 

select *
  from (select rownum as rn, a.*
          from (select aa.title,
                       aa.url,
                       bb.times,
                       bb.makedate,
                       bb.maketime,
                       (select title from menu kk where kk.id = aa.pid) menulevelfouth
                  from menu aa,
                       (select count(*) times,
                               title,
                               max(id) id,
                               max(makedate) makedate,
                               max(maketime) maketime
                          from menulog
                         group by title
                         order by count(*) desc) bb
                 where aa.id = bb.id) a)
 where rn between 0 and 4

 

select * from ( select rownum as rn , a.* from( select aa.title,aa.url,bb.times, bb.makedate ,cc.title from menu aa,
(select count(*) times,title , max(id) id,max(makedate) makedate from menulog group by title order by count(*) desc ) bb where aa.id=bb.id and aa.pid =cc.id) a) where rn between 0 and 6
