The partitions are not static and it will be changing frequently. I am trying to handle of getting the latest partition in the query. Can anybody help me to write the query?

Try this:

select * 
  from your_table t
 where concat_ws('-',t.year,t.month,t.date) in (select max(concat_ws('-',s.year,s.month,s.date)) from your_table s)
