Question

I have a table where I have some records as follows

Model            Make            Color
==================================================
Maruti 800       2008            Black
Maruti 800       2009            White
Maruti Esteem    2000            Yelow
Maruti Esteem    2010            Red

Now I want the Model, Make and Color which has maximum make in the list.
I have tried writing query like this

SELECT 
     Model,
     MAX(Model),
     Color
from 
     tableName
GROUP BY 
     Model,
     Color

But the result are not coming which I would like
It should be like

Model            Make            Color
===================================================
Maruti 800       2009            White    
Maruti Esteem    2010            Red

But the result is the whole table.

I need only those record which has max Make Model Wise.
I have also tried inner Query (co-related query) But in that also it is asking for group by.

The query below supports on all RDBMS including MySQL, Oracle, SQL Server,…

SELECT  a.*
FROM    tableName a
        INNER JOIN
        (
            SELECT  Model, MAX(Make) maxMake
            FROM tableName
            GROUP BY Model
        ) b ON a.Model = b.model AND
                a.make = b.MaxMake

if your RDBMS supports windows function,

SELECT  Model, Make, Color
FROM    
        (
            SELECT  Model, Make, Color,
                    ROW_NUMBER() OVER (Partition By Model ORDER BY Make DESC) rn
            FROM tableName
        ) b 
WHERE rn = 1

or

WITH lists
AS
(
    SELECT  Model, Make, Color,
            ROW_NUMBER() OVER (Partition By Model ORDER BY Make DESC) rn
    FROM tableName
) 
SELECT  Model, Make, Color
FROM    lists
WHERE rn = 1
