Select one unique record from DB table with the latest date

I have a file_store table like below.

I would like to select the latest records for each filetype_id.

The SQL to do this can be like this.

 SELECT f.file_id,f.FILETYPE_ID, f.file_obj_l,max_date  
 FROM FILE_STORE f inner JOIN   
 (SELECT FILETYPE_ID, max(f1.UPDATETS) as max_date FROM FILE_STORE f1  
 where FILETYPE_ID in (1, 2, 3)   
  group by FILETYPE_ID  
 ) a  
 on a.FILETYPE_ID = f.FILETYPE_ID and a.max_date = f.UPDATETS
