5       100             b           "
6       102             c           "

I want to latest 2 result of userid 100 and 102. This is the situation to understand the problem. Actually I have a list of userid and I want the latest n result of userid which is in my list of userid.

Answer 1

This was very difficult to understand but I’ll give you three possible answers:

1) If you want the results by the highest user iD (“latest” could mean that), you should do

select * from table
order by userId desc
limit 0, 2

2) If you want them ordered by creation date (which “latest” could also mean), type

select * from table
order by created_date desc
limit 0, 2

3) if your “list of userid” is another table, you want to join it

select t.* from table t
inner join list_of_userid u
on u.userid = t.userid
order by created_date desc
limit 0, 2

If you actually want something else, you’ll have to explain it 🙂
