轮数UP到10的倍数

Question

如何在PostgreSQL中轻松将数字UP上升到10的倍数？

例:

In      Out
100 --> 100
111 --> 120
123 --> 130

样本数据:

create table sample(mynumber numeric);

insert into sample values (100);
insert into sample values (111);
insert into sample values (123);

我可以用:

select 
 mynumber,
 case
    when mynumber = round(mynumber,-1) then mynumber 
    else round(mynumber,-1) + 10 end as result
from
 sample;

这很好用,但看起来很难看.有更简单的方法吗？

Answer 1

select ceil(a::numeric / 10) * 10
from (values (100), (111), (123)) s(a);
 ?column?
