limiting the # of rows in a query

Hello and thanks in advance for looking at this.

I'd like to select the 10 most recent items added to my database table. I'd like to pick these 10 items by the date they were added to the db.

Each of these items has a title AND a category. I'd like to get the 10 results and then group them by their category names.

Any ideas as to how I can go about accomplishing this?

1) Make sure you have a 'CREATED_ON' field in your table.  Populate this field when inserting with the sysdate (oracle) or Now() (access).  These also include time stamps so it will contain the date and time of the entry.

2) Perform a sub-query to order the data by your 'CREATED_ON' field - this will give you the most recent entries first.  With the outer query return the sub set of 10 rows and order it by the field you desire.  Here is an example:

select title, category
  from (
     select *
       from table
      order by created_on desc
        )
 where rownum < 11
order by title ;

Hope this helps!!

Actually, the answer was a combination of the two replies received. I will look to split the points between you two and thank you both very much.

I am using SQL, not Oracle, here's what the query ended up looking like and it works great.

select title, category
 from (
    select top 10 *
    from table
    order by created_on desc
       )
order by category;

thanks again

Points reduced for split.  Now you can accept an experts comment as an answer.  After that, make another question in this topic area for the other expert.
