同时在同一数据库上进行相同查询但结果不同？？ [大查询]

Question

我正在使用 Google Big Query 在数据集上执行一些 mysql 类型的查询。这两个查询几乎相同（它们仅在使用 SELECT 检索的 2 列的顺序上有所不同，所有其他 parameters/conditions 都相同）但是当在同一数据库上一个接一个地执行时，它们会给出两个不同的输出.我是 BigQuery 的初学者，也是 MySQL。请帮助。

查询及结果如下

查询 1：

SELECT web100_log_entry.snap.MinRTT AS rttval,
       web100_log_entry.connection_spec.remote_ip AS rip
FROM [measurement-lab:m_lab.2010_01]
WHERE IS_EXPLICITLY_DEFINED(connection_spec.client_geolocation.continent_code)
  AND IS_EXPLICITLY_DEFINED(web100_log_entry.log_time)
  AND IS_EXPLICITLY_DEFINED(connection_spec.client_geolocation.country_code)
  AND IS_EXPLICITLY_DEFINED(web100_log_entry.snap.MinRTT)
  AND web100_log_entry.log_time > 1262304000
  AND web100_log_entry.log_time < 1262476800
  AND connection_spec.client_geolocation.continent_code='EU'
  AND connection_spec.client_geolocation.country_code='FR'

查询 2：

SELECT web100_log_entry.connection_spec.remote_ip AS rip,
       web100_log_entry.snap.MinRTT AS rttval
FROM [measurement-lab:m_lab.2010_01]
WHERE IS_EXPLICITLY_DEFINED(connection_spec.client_geolocation.continent_code)
  AND IS_EXPLICITLY_DEFINED(web100_log_entry.log_time)
  AND IS_EXPLICITLY_DEFINED(connection_spec.client_geolocation.country_code)
  AND IS_EXPLICITLY_DEFINED(web100_log_entry.snap.MinRTT)
  AND web100_log_entry.log_time > 1262304000
  AND web100_log_entry.log_time < 1262476800
  AND connection_spec.client_geolocation.continent_code='EU'
  AND connection_spec.client_geolocation.country_code='FR'

你这里粘贴的只是第一个显示的结果页，总共有3254299行，而且它们的顺序不同（即使是同一个查询也可能有不同的顺序），因为没有ORDER BY 子句。
