Determine four highest numbers from DB

Got this interesting problem, I have a table and in there I have a field called itemid which is set to integer, and basically its a list of numbers.

The problem is, how do you go about calculating the 4 highest numbers?

I've tried using SQL command but I don't think I have the version which support sub selects

select * from t where number in (select max(number) from t)

Thanks in advance :o)

Under SQL Server or Access this would be:

Select Top 4 * From t Order By number Desc

I would try something similar in MySQL ... though not all DBMS' implement "Top".

well in mysql you could

SELECT number_feild FROM table ORDER DESC LIMIT 0,4

The limit starts the first record and returns the four values. If that does not work it is 4,0 :)

Thanks UKGimp,

That works :o)

I've ammended the query just slightly because it didn't work first time round, I put the 'ORDER by itemid' in the query.

SELECT prop_date,heading FROM newsfeed ORDER by itemid DESC LIMIT 0,4;

Thanks everyone.
