我想计算 Amazon Athena 中的第一个四分位数、中位数、第三个四分位数和第 99 个百分位数,其中数据库和表是从 Glue Data Catalog 创建的。
我输入的示例查询是:
select
percentile_cont(0.25) within group (order by duration column_name) as percentile_25,
percentile_cont(0.50) within group (order by duration column_name) as percentile_50,
percentile_cont(0.75) within group (order by duration column_name) as percentile_75,
percentile_cont(0.95) within group (order by duration column_name) as percentile_95
from "schema"."table_name";
还有什么其他方法可以计算四分位数?
