如何检索过去某个时间的标签数量
How to retrieve number of tags at a certain time in the past
我可以看到 如何通过 StackExchange API 获取标签数量。是否可以获取过去某个时间的标签数量？
我怎样才能运行https://api.stackexchange.com/2.2/tags?order=desc&sort=popular&inname=java&site=Whosebug with BigQuery？
可能的众多选项之一 - 对于 BigQuery 标准 SQL
#standardSQL
SELECT tag, COUNT(1) AS popular
FROM `bigquery-public-data.Whosebug.Whosebug_posts`,
UNNEST(SPLIT(tags, '|')) AS tag
WHERE DATE(creation_date)
BETWEEN DATE_SUB(CURRENT_DATE(), INTERVAL 3 YEAR)
AND DATE_SUB(CURRENT_DATE(), INTERVAL 2 YEAR)
GROUP BY tag
HAVING tag LIKE '%java%'
ORDER BY popular DESC
-- LIMIT 100
