Question

我试图根据某些标准返回一份明确的患者名单。我使用内部联接查看符合特定条件的所有患者记录，然后查看MAX服务日期，并进一步查看当天的MAX费用，以强制执行唯一记录。以下是一个简短的例子，显示患者可能在同一服务日期有4次收费。

我想在当天拉出MAX充电以获得明显的记录匹配。但是，我目前的代码是将MAX服务日期与任何找到的服务日期的MAX费用连接起来，创建一个假设记录，如上例所示：

10/3/2016   9/30/2016   Sebert, Stephen L MD  76598   CHG   238

此记录在数据库中不存在，因此我丢失了计数而没有返回匹配以获取患者人口统计信息。我希望这是有道理的。这是我的代码。我使用内部联接来做到这一点。如果有更好的方法，请告诉我。我是否需要进行第二次嵌套内连接才能完成此操作？

预期结果将是上图中的最高记录，费用为217.非常感谢您提供的任何帮助。谢谢！

Answer 1

您不仅要在子查询中对患者进行分组，还要对DNCP_FROMSERVICEDATE进行分组，这样您唯一的最大值就是DNCP_AMOUNT_CHARGE，这样您就可以获得当天的患者列表以及当天的最高费用，然后您就拥有以某种方式过滤，因为你会得到每个病人的倍数，主要查询或日期过滤器上的更多分组或主查询上的MAX（DNCP_AMOUNT_CHARGE），这是你从子查询中提取的唯一列。

希望它有意义。
