Select records with most recent date for groups of points

Hi all, 

 

I am working with a feature class (sample_Locations) in an ArcSDE Geodatabase and my table has a "Point" field and a "Date" field, the field types are string and date, respectively.  There are over 2000 features in the table and the point ID's are not unique, there are only ~100 point ID's, so there may be many points with the same Point ID.  I am trying to select records from the table with the most recent date for sets of values, where the field "Point" is the field that contains the values that define groups.

 

 

 

I have tried using the following subquery, but it did not select the correct records.  It selected a very random assortment of features.

 

[Date] in (SELECT max( [Date] ) FROM Sample_Locations GROUP BY [Point])

 

 

 

Can anyone provide help for performing this selection using a Python script?  Ideally, I would like to select the features and export these selected features to a standalone excel table.

 

Any help would be greatly appreciated!!

 

Jason
