SQL 2000 Query Assistance

First and foremost, this is for SQL 2000 not SQL 2005. The client is on SQL 2000 until July of this year, so having a coding method that will work in both SQL 2000 and SQL 2005 will be nice.

Currently whats happening is when I run the

SELECT * FROM cusMMElig WHERE PatientProfileId = '241742' and AppDate = '08/04/2007' I get back three rows. I am getting back three rows because the client changed the ApptStatus 3 times. The problem with this code is that its pulling the first apptstatus as the apptstatus, when in fact I would want the most recent one.

This is the Join causing the issue:

LEFT OUTER JOIN dbo.cusCRIMedLists crml4 ON E.EligAppStatMId = crml4.MedListsId

Essentially, I want the most recent row not the first created row.
SET NOCOUNT ON

SELECT PatientName = CASE WHEN RTRIM(pp.Last + ' ' + ISNULL(pp.Suffix, '')) <> ''
                           THEN RTRIM(RTRIM(pp.Last + ' ' + ISNULL(pp.Suffix, ''))
                                      + ', ' + ISNULL(pp.First, '') + ' '
                                      + ISNULL(pp.Middle, ''))
                           ELSE RTRIM(ISNULL(pp.First, '') + ' '
                                      + ISNULL(pp.Middle, ''))

use this

SELECT PatientProfileId, max(AppDate) MostRecentDate
FROM cusMMElig
group by PatientProfileId

then if you join this with original table

create view v_cusMMElig as
select * from cusMMElig c inner join (
SELECT PatientProfileId, max(AppDate) MostRecentDate
FROM cusMMElig
group by PatientProfileId
) m on c.PatientProfileId=m.PatientProfileId and c.AppDate=m.MostRecentDate

this view will give you most recent records per PatientProfileId. then use this view instead of table on your original post...

so add this subquery...

you may need to extend the correlation data if profileid isn't the correct level of "Key" columns
