我尝试了两种不同的方法来执行此查询，但我收到 Table too large for join for first 和 Resources 在第二个查询执行期间超出...

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)

你知道其他的尝试方法吗？！

非常感谢...

【解决方案1】：

您的问题严重缺乏元数据。你的表有多大，第一个表的连接在哪里等等。但是：

1) 试试JOIN EACH。您可以使用 this visualisation as a guide 更具体地使用连接。
2）尝试保存表格并允许较大的结果。
