BigQuery表对于JOIN＆amp;而言太大了查询执行期间超出资源

Question

我尝试了两种不同的方法来执行此查询，但是我收到的表太大了，无法连接第一个，而第二个查询执行期间资源超出了...

这些查询：

SELECT COUNT(DISTINCT(s_pageview_id)) as total
FROM impressions.tbl_impressions_201405
WHERE i_browser IN (1)
AND fk_i_id_tbl_vertical IN (1)
AND i_section IN (1)
AND s_ads_list != ''
AND b_is_human = true
AND DATE(dt_date) = '2014-05-28'
AND s_pageview_id NOT IN (
  SELECT s_pageview_id
  FROM impressions.tbl_impressions_201405
  WHERE i_section IN (26,27,83,96)
  AND i_browser IN (1)
  AND fk_i_id_tbl_vertical IN (1)
  AND DATE(dt_date) = '2014-05-28'
  AND s_ads_list != ''
  AND b_is_human = true
)

第二次查询：

SELECT COUNT(*) AS total
FROM impressions.tbl_impressions_201405 as impressions_1
LEFT OUTER JOIN EACH impressions.tbl_impressions_201405 as impressions_2
ON impressions_1.s_pageview_id = impressions_2.s_pageview_id
WHERE impressions_2.i_browser IN (1)
AND impressions_2.fk_i_id_tbl_vertical IN (1)
AND impressions_2.i_section IN (1)
AND impressions_2.b_is_human = true
AND DATE(impressions_2.dt_date) = '2014-05-28'
AND impressions_1.i_section IN (26,27,83,96)

你知道其他任何尝试方法吗？！

非常感谢你......

您的问题严重缺乏元数据。你的桌子有多大，第一个的连接在哪里等等。但是：

1）尝试JOIN EACH。使用this visualisation as a guide，您可以更加具体地使用联接 2）尝试保存表并允许大的结果。
