基于当前日期时间的值（外部表中的当前日期时间）

Question

当前，我有要根据最新日期和时间提取的数据。日期时间在外部表中列出，该外部表是通过联接聚集在一起的。

Date_Local                 Name     Value
2019-08-13 10:30:54.377    Ted       20
2019-08-13 10:30:54.377    Jake      50
2019-08-12 09:10:55.377     Ben      30

       Name,
       Value,
       Date_Local
FROM tblaData
) AS sub ON(T.Date_Local=sub.Date_Local)
WHERE sub.rowNum>1
