【问题描述】：

我想查询我的数据集（表）以获取包含 user_ids、日期、事件名称和事件参数键的列。我还指定我只想要“LeaveReview”事件。

fruit <- query_exec(
"SELECT user_dim.user_id, event.date, event.name, event_param.key,
FROM `table_201804*`,
UNNEST(event_dim) as event,
UNNEST(event.params) as event_param
WHERE event.name = 'LeaveReview'
AND _TABLE_SUFFIX BETWEEN '01' AND '25'
LIMIT 40",
project = "my_table"

)

我将如何修改我的代码以仅获取在给定日期同时执行“LeaveReview”和“ClickFavorite”的用户的信息？我尝试了以下方法，但这不起作用：

fruit <- query_exec(
"SELECT user_dim.user_id, event.date, event.name, event_param.key,
FROM `table_201804*`,
UNNEST(event_dim) as event,
UNNEST(event.params) as event_param
WHERE (event.name = 'LeaveReview' AND event.name = 'ClickFavorite')
AND _TABLE_SUFFIX BETWEEN '01' AND '25'
LIMIT 40",
project = "my_table"

)

如果我执行以下操作，我会得到执行事件“ClickFavorite”的人，而不是事件“LeaveReview”或其他方式的人：

fruit <- query_exec(
"SELECT user_dim.user_id, event.date, event.name, event_param.key,
FROM `table_201804*`,
UNNEST(event_dim) as event,
UNNEST(event.params) as event_param
WHERE (event.name = 'LeaveReview' OR event.name = 'ClickFavorite')
AND _TABLE_SUFFIX BETWEEN '01' AND '25'
LIMIT 40",
project = "my_table"

)

【参考方案1】：

嗯。这样的事情有用吗？

SELECT user_dim.user_id
FROM `table_201804*`,
     UNNEST(event_dim) as event,
     UNNEST(event.params) as event_param
WHERE event.name  IN ('LeaveReview', 'ClickFavorite')
GROUP BY user_dim.user_id
HAVING COUNT(DISTINCT event.name) = 2;

【讨论】：

我仍然想要所有其他信息，例如事件名称、日期和密钥，但我不能包含它们，因为它会给我一个警告“错误：SELECT 列表表达式引用事件。既不分组也不聚合的名称”
