Oracle select last record for a particular id

Question

I have a table in oracle 11g like this:

id   date  
---  ---
1    1-jun
1    2-jun
1    3-jun
2    1-jul
2    2-jul
2    3-jul

I am trying to extract the latest record corresponding to each id. I tried group by, max but I cannot get it to work. What I want is:

   id    date 
   ---   ---
    1    3-jun
    2    3-jul

Answer 1

Try this:

SELECT id, MAX(date)
  FROM <YOUR-TABLE>
 GROUP BY id

Answer 2

试试这个

'SELECT *FROM (SELECT * FROM table ORDER BY date   DESC )tmp GROUP BY Id ';
