Multiple max values in a query

Question

I know the title does not sound very descriptive, but it is the best I could think of:

I have this table

ID     BDATE      VALUE
28911  14/4/2009  44820
2         


        

Answer 1

We can use multiply columns in an IN clause:

select id, bdate, value 
from myview 
where (id, bdate) in
    (select id, max(bdate)
     from myview group by id)
/
