sql - Presto SQL 全外连接

Question

我有一个完全加入，它不像我预期的那样工作。

我加入了 4 列。但是，其中一列有一些空白值，导致出现一些数字[unjoint. 当我删除此列时，查询有效。但是，我必须为报告设置此特定列，因为这是我们报告数字的方式。

有问题的查询：（不起作用的列是 OM.line_item_id）

SELECT DBM.dated, DBM.line_item, DBM.line_item_id, DBM.insertion_order, DBM.insertion_order_id, DBM.device_type, DBM.market, DBM.impressions, DBM.clicks, DBM.amount_spent_EUR, OM.orders, OM.revenue, OM.device

FROM
(

SELECT
DATE_FORMAT(DATE_PARSE(date,'%Y/%m/%d'),'%Y-%m-%d') AS dated, line_item, line_item_id, insertion_order, insertion_order_id, device_type, trim(SPLIT_PART(insertion_order,'|',3)) AS market, cast(impressions as double) as impressions, cast(clicks as double) as clicks, CAST(media_cost_advertiser_currency AS DOUBLE)*1.15 AS amount_spent_EUR


FROM ralph_lauren_google_sheet_dbm_data  

WHERE dated >= '2019-03-31'
AND dated <= {{days_ago 1}}

GROUP BY 1,2,3,4,5,6,7,8,9,10

)DBM 

FULL outer JOIN

( 

SELECT dated, line_item_id, device, market, sum(orders) as orders, sum(revenue)+sum(shipping_revenue)-sum(coupon_discount) as revenue

FROM

(
select

    ELSE Sum(TRY_CAST(revenue AS DOUBLE)*1)
    END as revenue,

    END as coupon_discount

from ralph_lauren_ftp_all_eu_markets_ltc  

WHERE dated >= '2019-03-31'
AND dated <= {{days_ago 1}}

and last_touch_channel like 'Retargeting' 

and lower(utm_medium_v21) not like '%fbig%'

and cast(orders as bigint) > 0


group by
1,2,3,4,5
)

GROUP BY 

1,2,3 ,4-- revenue numbers are getting duplicated for some reason

)OM

ON

DBM.dated = OM.dated AND DBM.line_item_id = OM.line_item_id and DBM.device_type = OM.device AND DBM.market = OM.market

如果将其他三列连接起来，完全外部连接不会允许我连接数字吗？

谢谢
