      1.分頁模板

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

      2 某個(gè)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(gè)實(shí)例

      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

       where aa.id = bb.id
         and aa.pid = cc.id
         and aa.title like '%醫(yī)療賬單錄入清單%'
