这是一个简单的问题，但我并不完全明白出现了什么问题......我正在使用的方法。所以我已经回到原来需要使用的两个表了。因此，如果你能从一开始就建议如何解决这个问题，我将不胜感激。 一个表是案例，其中包含个别案例详细信息，日期可用于计算，雇用的持续时间和应用的费率。它有一个源ID，它与预算表有共同之处。每个案例都有一个来源ID。另一个表是每个日历月的源ID预算。需要比较日期的实际收入和案例中的费率，并将它们与实际预算进行比较和比较。
用于计算持续时间的日期是实际结束日期的实际开始日期，但为了使问题更加复杂，只需要返回感兴趣的月份的租用天数。因此，如果雇用的开始时间早于相关月份，则只需将这些日期与该月的预算进行比较。 唯一的另一个要求是根据公司名称设定费率，合同费率或雇用每日费率。但我尽量保持简单。
这是所有演示数据......
