Question

I have a table that has an integer id (primary key) and timestamp date added columns (among others).

what would the syntax to extract the id values for the ten most recent “date added” values look like?

Answer 1

If we go by the title of your question (10 most recent rows):

SELECT `id`
  FROM `table`
 ORDER BY `date added` DESC
 LIMIT 10

If we go by what you say in your question (10 most recent values of date added):

SELECT `id`
  FROM `table`
 WHERE `date added` IN ( SELECT DISTINCT `date added`
                           FROM `table`
                          ORDER BY `date added` DESC
                          LIMIT 10 )

As I noted in my comments, I use Transact-SQL primarily so you might need to adjust for any gaps in my MySQL knowledge.
