如何解决此语法错误？

Question

我试图编写一个查询来为电子邮件提取客户数据。这是查询：

select 
opp.* 
from 
(
select 
opp.*, 
row_number() over (partition by opp.contact_email_address order by opp.status_date desc) as row_number 
from 
opportunity_data opp 
where 
opp.site = 'wesellinsurance' 
and opp.email_bounced = 'false' 
and opp.email_unsubscribed = 'false' 
and opp.first_mkt_medium not in ('partner', 'inbound_outbound') 
and opp.latest_mkt_medium not in ('partner','inbound_outbound') 
and opp.on_cover = 'false' 
and opp.primary_group in ('market_trader', 'food_stand', 'mobile_food_van', 'caterer') 
and opp.opportunity_status = ('quote_recieved','rfq_submitted', 'policy_expired_not_renewed') 
and datediff(day, cast(latest_rfq_submitted_date as date),cast(getdate() as date)) > 30 
and opp.lifecycle = 'new_business' 
) opp 
where row_number = 1 

大多数语法分析器说那里有第7行的问题，但我不能似乎看到它

错误的是（有应该是（in）而不是（=）并且始终指定一个表名称BEST PRACTICE（opp1.row_number））

select 
     opp1.* 
     from 
     (
     select 
     opp.*, 
     row_number() over (partition by opp.contact_email_address order by opp.status_date desc) as row_number 
     from 
     opportunity_data opp 
     where 
     opp.site = 'wesellinsurance' 
     and opp.email_bounced = 'false' 
     and opp.email_unsubscribed = 'false' 
     and opp.first_mkt_medium not in ('partner', 'inbound_outbound') 
     and opp.latest_mkt_medium not in ('partner','inbound_outbound') 
     and opp.on_cover = 'false' 
     and opp.primary_group in ('market_trader', 'food_stand', 'mobile_food_van', 'caterer') 
     and opp.opportunity_status in ('quote_recieved','rfq_submitted', 'policy_expired_not_renewed') 
     and datediff(day, cast(latest_rfq_submitted_date as date),cast(getdate() as date)) > 30 
     and opp.lifecycle = 'new_business' 
     ) opp1 
     where opp1.row_number = 1
