Oracle中通过组内排序实现行转列（三）

1 纵表平铺

1.1 原数据

 1.2 平铺

结果：每个班级按照年龄从小到大平铺为一行

select *
  from (select rt.class,
               row_number() over(partition by rt.class order by rt.age) row_num,
               rt.sno,
               rt.sname
          from rank_test rt
         order by rt.class, rt.age)
pivot(max(sno) sno, max(sname) as sname
   for row_num in('1' as sno1, '2' as sno2, '3' as sno3, '4' as sno4))
