Question

我对SQL很新，我认为这是一个快速修复：下面是我们办公室中使用的软件的当前Raw SQL。我想在“pronotes”表中添加一个返回最新条目日期的列，其中pronotes.subject =“Patient Contact”。该列标题为“Last Pt.Contact”。我不知道这是否是足够的信息，或者这是一个快速解决方案还是一个大问题。提前感谢你。

编辑这是表格结构。 OT的主键看起来是Orderno

您需要找到患者的最新日期。我建议你在你在主查询中加入的子查询中这样做。

SELECT
  ...
  LastPatientContact.Date as 'Last Pt. Contact'
FROM OT
  ...
LEFT JOIN (
  SELECT MRN, MAX(date) as Date
  FROM pronotes
  WHERE subject = 'Patient Contact'
  GROUP BY MRN
) LastPatientContact
  ON LastPatientContact.MRN = OT.MRN

添加列，该列返回给定特定主题的最新条目的日期
