postgresql 实现查询某时间区间的所有日期案例

select daytime::date from generate_series(
('2017-06-01'),--查询开始日期（可根据需求调整） 
(select now()::date),--查询结束日期（可根据需求调整） 
 '1 day'--间隔（可根据需求调整）
) s(daytime)

select daytime,periods from (select daytime::date
from generate_series(
(select min(score_date) from tableA),--查询开始日期
(select now()::date),--查询结束日期
  '1 day'--间隔
) s(daytime)) t ,tableA where 
(t.daytime >((substr(time_period,0,5)||'-'||substr(time_period,5,2)||'-'||substr(time_period,7,2))::timestamp + '-1 day')::date ) 
and t.daytime <((substr(time_period,10,4)||'-'||substr(time_period,14,2)||'-'||substr(time_period,16,2))::timestamp + '1 day')::date

select max(created_date),min(created_date) from biz_retail_order where source_order_no like '%daling_qa11184_%' and created_date > '2020-11-18 15:30:00' ;
