Question

This is my current SQL query:

SELECT 
   ROW_NUMBER() OVER(PARTITION BY [Machine_ID] ORDER BY Version DESC) AS ROW, 
   MachineList.*
FROM  
   MachineList

Basically, I want to get distinct machine information. If several machines have the same ID, then choose the one with latest version.

However, SQL Server 2000 does not support the ROW_Number function. Is there any alternative for the SQL above?

P.S. most solutions I found on line are using temp table. But I could not use temp table because this query will be used in SSIS.

Answer 1

 select m.*
 from machinelist as m
        inner join (
               select
                     t.machine_id, max(t.version) as version
               from machinelist as t
               group by t.machine_id
        ) as mm on
              mm.machine_id = m.machine_id and mm.version = m.version
