Have you tried using DISTINCT?

Sean Wee 18-Jun-13 20:57pm

I try use this:

SELECT Name, Country, MAX(Status) as Status FROM (
SELECT TOP 100 PERCENT *
FROM NameCountry
ORDER BY Name ASC, Country ASC, Status DESC
) G
GROUP BY G.Name, G.Country
ORDER BY G.Name, G.Country

and it only work for sql but not hsqldb.

You can use select distinct to get each value only once.

select distinct name, country from table where status = 'updated' However, if you did a select distinct on all three columns, you'd get the pairs, pending and updated. I think you need to do what I just said, and then join that to a select that gets pending values that are not in this list. Really, your table design is broken. If the names are the same person, why do they have more than one status ?
