google-bigquery - BigQuery - JOIN 左侧的 UNION == 意外。请再试一次

Question

我对这个查询有疑问：

select 
sviEventoviFull.site_sectionid as site_sectionid,
sviEventoviFull.ev_date as ev_date,
sum(sviEventoviFull.total_views) as actualTotalViews,
sum(sviEventoviFull.total_visits) as actualTotalVisits,
sum(sviEventoviFull.total_time) as actualTotalTime,
sum(sviEventoviFull.realUserCount) as actualRealUserCount from
(select userid,site_sectionid,
    ev_date,
    total_views,
    total_visits,
    total_time,
    1 as realUserCount from
    DotMetric_TEST.EV_03112012,
    DotMetric_TEST.EV_04112012)

as sviEventoviFull 

join
    (
    select userid from DotMetric_TEST.UserSettings where 
    q1=100 
    and 
    q2=213 
    and 
    geo_code in (7,6,1,2)
    ) 
    as patternTablica
    on sviEventoviFull.userid =patternTablica.userid 
    where  sviEventoviFull.site_sectionid in (1,2,3,4,5,6,7,8,11,123)
    group by site_sectionid,ev_date

它一直告诉我“错误：意外。请重试。”。

没有 UNION 的相同查询按预期工作：

select 
sviEventoviFull.site_sectionid as site_sectionid,
sviEventoviFull.ev_date as ev_date,
sum(sviEventoviFull.total_views) as actualTotalViews,
sum(sviEventoviFull.total_visits) as actualTotalVisits,
sum(sviEventoviFull.total_time) as actualTotalTime,
sum(sviEventoviFull.realUserCount) as actualRealUserCount from
(select userid,site_sectionid,
    ev_date,
    total_views,
    total_visits,
    total_time,
    1 as realUserCount from
    DotMetric_TEST.EV_03112012)

as sviEventoviFull 

join
    (
    select userid from DotMetric_TEST.UserSettings where 
    q1=100 
    and 
    q2=213 
    and 
    geo_code in (7,6,1,2)
    ) 
    as patternTablica
    on sviEventoviFull.userid =patternTablica.userid 
    where  sviEventoviFull.site_sectionid in (1,2,3,4,5,6,7,8,11,123)
    group by site_sectionid,ev_date

请帮助我们解决这个问题以及如何一起使用 UNION 和 JOIN。连接左侧的 UNION 应该是非常常见的请求！
