1.分頁模板

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

2 某個表名

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 將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另外一個實例

 

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 '%醫(yī)療賬單錄入清單%'

復(fù)制代碼

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 '%醫(yī)療賬單錄入清單%'

                 where aa.id = bb.id) a)
 where rn between 0 and 4
