为什么在大查询中运行sql时，会得到一个意外的关键字间隔？

我得到了这个sql，我正试图在BigQuery中运行它。我收到这个错误：

意外关键字间隔

SELECT studio."Location" as location ,CONCAT(users.first_name, ',', users.last_name) AS username , COUNT(events.created_at) AS events    
FROM xxx    
JOIN zzz ON z_kf_asset = asset.z_kp    
JOIN client ON production.z_kf_client = client.z_kp    
JOIN studio ON client.z_kf_studio = studio.z_kp    
JOIN events ON events.asset_id = asset.z_kp    
JOIN users ON events.user_id = users."id"    
WHERE post_history IS NOT NULL    
AND events.created_at BETWEEN LOCALTIMESTAMP - INTERVAL '7 days' AND LOCALTIMESTAMP    
AND client.display_name = 'xxxxx'    
AND events.description = 'xxxxxxxx'    
GROUP BY location, username

非常感谢您的帮助

尼克在评论中给出了正确的答案。为完整起见，请在此转录：

而不是：

localtimestamp - INTERVAL '7 days'

做：

例如：

SELECT '2018-01-9' BETWEEN TIMESTAMP_SUB(localtimestamp, INTERVAL 7 DAY) AND localtimestamp
FROM (SELECT TIMESTAMP('2018-01-15') localtimestamp)

我认为BigQuery不支持这样的日期数学（即使用

-

操作符）。而且

“7天”

应该是

7天

。试试

DATE\u SUB（本地时间戳，间隔7天）

谢谢，它成功了！！！这一个怎么样？client.display_name='xxxxx'，显然不接受=。无法获取它。因此，应该是“和events.created”和“在日期和时间之间创建”和“SUB（LOCALTIMESTAMP，INTERVAL 7 DAY）”以及“LOCALTIMESTAMP和client.display”\u name='xxx'和events.description='xxxx'？非常感谢！

SELECT '2018-01-9' BETWEEN TIMESTAMP_SUB(localtimestamp, INTERVAL 7 DAY) AND localtimestamp
FROM (SELECT TIMESTAMP('2018-01-15') localtimestamp)
