Python中带有日期用户输入的Oracle SQL查询

我试图在python中运行SQL查询，但在使用用户输入传递日期时遇到错误，该错误不是有效的月份

该表有一个MM/DD/YYYY格式的日期列。我以YYYY-MM-DD的形式传递日期

这是问题所在

SELECT
  substr(PLACEMENT_DESC, 1, INSTR(PLACEMENT_DESC, '.', 1) - 1) AS "'Placement#'",
  SUM(VIEWS) AS "'Delivered_Impresion'",
  SUM(CLICKS) AS "'Clicks'",
  SUM(CONVERSIONS) AS "'Conversion'"
FROM TFR_REP.DAILY_SALES_MV
WHERE (IO_ID = {})
AND (DAY_DESC BETWEEN to_char(TO_DATE(TO_CHAR('{}'), 'MM/DD/YYYY'), 'YYYY-MM-DD')
AND to_char(TO_DATE(TO_CHAR('{}'), 'MM/DD/YYYY'), 'YYYY-MM-DD'))
GROUP BY PLACEMENT_ID,
         PLACEMENT_DESC
ORDER BY PLACEMENT_ID".format(self.config.IO_ID, self.config.SDATE, self.config.EDATE)

以下是python代码： 代码太大了，所以我只是把阅读SQL的一部分放进去

假设您以YYYY-MM-DD格式传递日期，并且DAY_DESC是日期类型，则可以使用日期文字，这是ANSI标准，避免使用日期

该表有一个MM/DD/YYYY格式的日期列

日期数据类型在数据库中没有任何格式。它只是根据会话参数的不同而变化的显示。但是，如果您的意思是DAY_DESC是字符串CHAR/VARCHAR2type，则可以在将其转换为以下形式后使用：

TO_DATE(DAY_DESC,'MM/DD/YYYY') BETWEEN DATE '{}' AND DATE '{}'

---

请避免在数据库中以字符串形式存储日期。

表中DAY_DESC的数据类型是什么？能否发布python代码？@Fire See edited post.im对panda不太熟悉，但能否打印self.config.SDATE和self.config.EDATE，以查看它们是否符合您指定的格式

TO_DATE(DAY_DESC,'MM/DD/YYYY') BETWEEN DATE '{}' AND DATE '{}'
