hive获取这周五到下周四的区间，周一到周日的区间

本文主要是介绍hive获取这周五到下周四的区间，周一到周日的区间，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

-- 获取每个日期所在周期的开始和结束时间
SELECTcreated_date AS date_in_period,CASEWHEN date_format(created_date, 'u') < 5 THEN date_sub(created_date, cast(date_format(created_date, 'u') AS INT) + 2)ELSE date_sub(created_date, cast(date_format(created_date, 'u') AS INT) - 5)END AS period_start,CASEWHEN date_format(created_date, 'u') < 5 THEN date_add(created_date, 4 - cast(date_format(created_date, 'u') AS INT))ELSE date_add(created_date, 11 - cast(date_format(created_date, 'u') AS INT))END AS period_end,date_format(created_date, 'u') actual_week
FROM ods_ticket_full
where dt = '2024-05-10';

获取周一到周日的星期区间
