【问题描述】：

不幸的是，我在原生 sql 查询中通过 date 过滤而苦苦挣扎了好几个小时。有人有深厚的元数据库经验吗？

select to_date("date", 'YYYYMMDD') AS Date, 
round(sum("price"), 2) AS "Revenue"
from "cdw_transactions"
group by Date
WHERE Date = Date

【参考方案1】：

查询应改写为：

select to_date("date", 'YYYYMMDD') AS "Date", 
round(sum("price"), 2) AS "Revenue"
from "cdw_transactions"
where "date" = Date               -- where before grouping
group by to_date("date", 'YYYYMMDD'); -- matching select

【参考方案2】：

您应该在group by 之前过滤。但是，实际上不需要 group by，因为您只想返回一行。

我认为是这样的：

select Date AS Date, 
       round(sum("price"), 2) AS "Revenue"
from "cdw_transactions"
where to_date("date", 'YYYYMMDD') = Date;
