我试图以多种方式重新编写此查询，并且我不断收到不同的错误。基本上，我试图根据＆＃34;何时＆＃34;加入选项A或B？案例陈述的一部分是真实的。当我不使用案例stmt时，它工作正常。
案件的原因是我们在星期日从2a-8a停机。所以，我需要考虑那个时间并从delivery_time中减去它。
这是我得到的错误：
ORA-00905：缺少关键字 00905. 00000 - ＆＃34;缺少关键字＆＃34;
以下是无效的查询：

我希望您的问题是不为子查询提供别名。

就像Kordirko所说，你的ON条款可以更简单。
ON trunc（（ct.delivery_time-ct.la_promote_time）* 24 * 60）BETWEEN rng_start和rng_stop / *你比较整数，不需要转换为字符串* /
等等。
但这就是你想要的吗？
