Question

我想隔离一些带有特定标题的电子邮件。我可以在where子句中使用多个与OR关联的“ like”。这给了我很多结果。但是，如果我尝试在（'____'，'____'等）中执行____，则代码突然不返回任何内容。

这不起作用。

select DATE_TRUNC(DATE(send_time,"America/Los_Angeles"), week(monday)) as week,
status, 
settings_title,
sum(emails_sent) as emails_sent,
sum(report_summary_opens) as report_summary_opens, 
sum(report_summary_unique_opens) as report_summary_unique_opens, 
sum(report_summary_subscriber_clicks) as report_summary_subscriber_clicks
from mailchimp.campaigns_view
where status = 'sent' 
and settings_title in ('%_LL_%', '%_IC_%', '%_AC_%', '%_CC_%', '%_PC_%')
group by 1,2,3
order by 1 desc

但是，这可行。

select DATE_TRUNC(DATE(send_time,"America/Los_Angeles"), week(monday)) as week,
status, 
settings_title,
sum(emails_sent) as emails_sent,
sum(report_summary_opens) as report_summary_opens, 
sum(report_summary_unique_opens) as report_summary_unique_opens, 
sum(report_summary_subscriber_clicks) as report_summary_subscriber_clicks
from mailchimp.campaigns_view
where status = 'sent' 
and (settings_title like '%_LL_%'
or settings_title like '%_IC_%'
or settings_title like '%_AC_%'
or settings_title like '%_CC_%'
or settings_title like '%_PC_%')
group by 1,2,3
order by 1 desc

我已经尝试在“来自”中包含一个子查询，以消除所有空的settings_title。任何想法为什么这不起作用？我是否缺少一些小的语法错误？

感谢您的帮助！

%符号仅与LIKE一起使用。对于IN，这只是平等。也尝试REGEXP_CONTAINS。

如：

SELECT REGEXP_CONTAINS("abcdefg", '(xxx|zzz|yyy|cd)')

BigQuery Query使用多个“点赞”，但不使用“ in”
