Question

Now I am with MS SQL Server 2008. I would like to know if it is possible to select top record of same group.I have 3 fields in my table. Here is my table

ID      GroupNo     FieldOfInterest  
0001    G1                  Football  
0002    G2                  Football  
0003    G2                  Basketball
0004    G3                  Golf
0005    G3                  Swimming  

I wanna select the record from this table like that

ID      GroupNo             FieldOfInterest  
0001    G1                  Football  
0002    G2                  Football  
0004    G3                  Golf  

How can I do this? Please help me .

Answer 1

SELECT t1.*
FROM table AS t1
INNER JOIN (
    SELECT MIN(ID) AS MinID
    FROM table
    GROUP BY GroupNo) AS t2
ON t1.id = t2.MinID

Assuming the “top record” means the record with the samllest ID, as you have not provided an order.
