Presto 学习和使用笔记

1.presto 表连接查询的连接条件中不支持使用函数

比如下面的脚本在presto中运行会报错

select t1.period_start_date, t2.statistic_date
from
(select
        distinct calendar_date as period_start_date, calendar_date as period_end_date
        from
            edw_public.dim_esf_edw_pub_date
        where  calendar_date >= '${开始时间}' and calendar_date <= '${结束时间}'
) t1
left join
(select
 statistic_date
,xf_agent_id	as agent_id
  from
      edw_agents.adm_xf_edw_agents_performance_daily_report_edw_001_di
      where 1=1
 ) t2 on date(statistic_date) <= period_start_date and date(statistic_date) <= period_end_date

但是只要把连接条件中的date函数去掉则可以正常运行

select t1.period_start_date, t2.statistic_date
from
(select
        distinct calendar_date as period_start_date, calendar_date as period_end_date
        from
            edw_public.dim_esf_edw_pub_date
        where  calendar_date >= '${开始时间}' and calendar_date <= '${结束时间}'
) t1
left join
(select
 statistic_date
,xf_agent_id	as agent_id
  from
      edw_agents.adm_xf_edw_agents_performance_daily_report_edw_001_di
      where 1=1
 ) t2 on statistic_date <= period_start_date and statistic_date <= period_end_date
