操纵Current_Date

Question

这是我的SQL查询：

select id, max(file_uploaded_at) as latest_date, current_date
from employee_imports
where convert(file_uploaded_at) - integer '90'< current_date AND
error_message IS NULL
group by id
order by latest_date DESC

尽管如此，我仍然会回溯超过90天的价值观。你知道为什么吗？

Answer 1

select id, max(file_uploaded_at) as latest_date, current_date
from employee_imports
where current_date - date(file_uploaded_at) <= 90 AND
error_message IS NULL
group by id
order by latest_date DESC

这是我更改查询的内容，一切似乎都正常。

无论如何，谢谢你们。
