I have the following table structure ,

name || description || timestamp varchar varchar date

time stamp column consists of time the row is added

Now i need to fetch the recently entered 5 records .. How should i query the table .

Note: i am using oracle 10g

Update :

select * from table orderby timestamp desc where rownum<6

Is that right approach ??

Thanks in advance !!

Because the where clause is applied first, and the order by is applied to the results, you need to use a subselect as follows:

select * from (
  select *
  from table
  order by timestamp desc
where rownum <= 5;

Why don't you try:

       `Select * From my_table
       Where Row_number<6
       Order by Timestamp Desc:

` I think it will work

This won't work: the where clause is applied first and then the order by. –  Colin 't Hart Feb 25 '14 at 9:32
