引用表别名时获取模式不存在错误

Question

当我尝试运行以下查询连接两个表时，出现错误：模式“u”不存在。

我哪里错了？

SELECT
       u.delivery_station_code AS dim_location,
       u.cycle_name AS dim_cycle_name,
      u.scac AS dim_scac,
       DATE(u.event_datetime) AS period_date,
       COUNT(DISTINCT u.scannable_id) AS Volume,
       v.mechanical_capacity AS mech_cap
FROM perfectmile_na.d_perfectmile_onroad_events as u
left join perfectmile_na.d_perfectmile_big_push_metrics as v
on
u.event_datetime=v.execution_date
and u.delivery_station_code= v.station_code
and u.cycle_name=v.cycle
WHERE DATE(u.event_datetime) between '2022-01-26' and '2022-02-03'
  AND ((shipment_type = 'Delivery' or shipment_pickup_instructions is NULL)) AND
      u.is_latest_by_shipment_status_and_eventdate = 'Y'
  AND u.shipment_status = 'PICKED_UP'
  AND dim_cycle_name in ('CYCLE_1', 'CYCLE_2', 'CYCLE_0')
  AND  (u.delivery_station_code like 'D%' or u.delivery_station_code like 'Z%')
  AND  u.scac ='AMAUS'
GROUP BY u.delivery_station_code, u.cycle_name, u.scac, u.DATE(u.event_datetime)```
