Google bigquery 选择没有任何事件具有特定值的ID BigQuery

我的表中有FULLVISITORIDS，具有不同的VisitId和eventCategory

我想选择FullvisitorID，其中eventCategory中没有一个是“A” 例如：

从my_表中选择*

FullVisitorid    Visitid   .... .....hits.event.eventCategory
    1              123                       A                       
                                             B                       
                                             E
    1              147                       D                       
                                             E                       
                                             E 
    2              555                       F
                                             G
                                             D

我只想要2作为我的最终输出

我尝试了以下代码，但似乎不起作用

Select fullvisitorid from  `my_table` where fullvisitorid not in (select distinct fullvisitorid from 
`my_table`, unnest(hits) hits where hits.event.eventCategory = 'A' )

---

谢谢你的帮助

以下查询获取嵌套命中记录中没有A的所有用户：

with all_visitors as (
-- Get a list of all FullVisitorid
  select distinct FullVisitorid from `project.dataset.my_table`
),
eventCategory_As as (
-- Get a list of all FullVistiroid with A eventCategory
  select distinct FullVistorid
  from `project.dataset.my_table`
  left join unnest(hits) h
  where h.event.eventCategory = 'A'
)
-- Left join to get FullVisitorid who don't have an A eventCategory
select
  a.FullVisitorid
from all_visitors a
left join eventCategory_As b on a.FullVistiorid = b.FullVisitorid
where b.FullVisitorid is null
