我有一个包含学生id和年龄的数据集。我想标记应该被安排在一个范围内或桶大小10桶。

stud_id    ages
101        11
102        13
103        21
104        25

同样，我有更多的记录日期。这个箱子的尺寸必须为10。
预期输出为：

stud_id     ages_bin
101         11-20
102         11-20
103         21-30
104         21-30

我在 hive 里试过简单的病例陈述。

select stud_id,
case when ages between 0 and 10 then '0-10'
when ages between 11 and 20 then '11-20'
when ages between 21 and 30 then '21-30'
when ages between 31 and 40 then '31-40'
when ages between 41 and 50 then '41-50'
when ages between 51 and 60 then '51-60'
when ages between 61 and 70 then '61-70'
when ages between 71 and 80 then '71-80'
when ages between 81 and 90 then '81-90'
when ages between 91 and 100 then '91-100'
when ages between 101 and 110 then '101-110'
when ages between 111 and 120 then '111-120'
when ages between 121 and 130 then '121-130'
when ages between 131 and 140 then '131-140'
when ages between 141 and 150 then '141-150'
else NULL end as ages_bin

有没有什么简单的方法可以让bucket大小为10的bined数据？
有人能帮我写一个简单的代码吗？
