sql语句按分数段划分维度

统计各分数段的数据数量

select id,score,date_month,
case when score <5 then '0-5' 
when score>=5 and score <10 then '5-10'
when score>=10 and score <20 then '10-20'
when score>=20 and score <30 then '20-30'
when score>=30 and score <50 then '30-50'
when score>=50 then '50以上'
end as interzone
from table1 B
WHERE is_deleted = 0 AND date_month = 'XXX'

统计各分数段的数据数量（某分数段无数据也存在）

select t3.id,t3.date_month,t3.interzone,t4.XX_id from
((select DISTINCT id,date_month,interzone from (
(select interzone from XX_interzone) t1
inner join
(select id,date_month from tablea where is_deleted = 0) t2)) as t3
left join (
select id,XX_id,date_month,
case when score <5 then '0-5' 
when score>=5 and score <10 then '5-10'
when score>=10 and score <20 then '10-20'
when score>=20 and score <30 then '20-30'
when score>=30 and score <50 then '30-50'
when score>=50 then '50以上'
end as interzone
from tableb
where is_deleted = 0 ) as t4
on t3.interzone=t4.interzone and t3.id=t4.id and t3.date_month=t4.date_month)
WHERE t3.id = 'XXX' AND t3.date_month = 'XXX'
