I have a table that looks like this: Id PageId Key Content LastUpdated ———————————————

  • 0

I have a table that looks like this:

Id    PageId    Key    Content    LastUpdated
---------------------------------------------

 1     12       key1    content1   02-21-2010
 2     12       key1    content2   02-25-2010
 3     12       key2    content1   02-21-2010
 4     12       key2    content2   02-25-2010
 5     12       key3    content1   02-21-2010

What I need to be able to do is query out a distinct list by PageId ordered by LastUpdated so my result would look like this:

2     12       key1    content2
4     12       key2    content2
5     12       key3    content1

I am using Linq-2-Sql but if I needed to I could use an SP. Any help on how to accomplish this would be great, thanks!

    Here’s one idea using just tsql that you could put in an SP. (Assumes that LastUpdated is a datetime field and not a string in the format you’ve listed and assumes at least SQL 2005 to use the CTE. Either of these assumptions can be overcome if they’re incorrect.):

    ;with cteMaxUpdated as (
    select Key, max(LastUpdated) as MaxUpdated
        from YourTable
        group by Key
)
select yt.Id, yt.PageId, yt.Key, yt.Content
    from cteMaxUpdated mu
        inner join YourTable yt
            on mu.Key = yt.Key
                and mu.MaxUpdated = yt.LastUpdated
