can i use aggregation function (LAST) in mysql??
if yes then why give me error for following query::

SELECT `user_id`,last(`value`)
FROM `My_TABLE`
group by `user_id`

ERROR:: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(value) FROM My_TABLE group by user_id' at line 1

EDIT:: I got answer "last" is not used in MySql. then How to perform it in MySql??

No, There is nothing called LAST in mysql

See the list of aggregated function

EDIT

You can perform the same something like this

select f.user_id, f.value
from (
   select  MAX(value) as maxval
   from my_table group by user_id
) as x inner join my_table as f on f.value = x.maxval

Something like this -

SELECT * FROM table1 t1
  JOIN (SELECT depno, MAX(id) max_id FROM table1 GROUP BY depno) t2
    ON t1.depno = t2.depno AND t1.id = t2.max_id
