Is there any simple solution?

SELECT MIN(Name),Code
FROM Table
GROUP BY Code

I considered that you want your results to be alphabetical.

SELECT
         MIN(Name), Code
FROM 
         MyTable 
GROUP BY 
         Code

SELECT MIN(c1), c2 FROM table GROUP BY c2 ORDER BY c2 ASC;

if your "TOP" is defined by "first in alphabtetical order", you could simply use a simple group by clause with the MIN aggregation.

SELECT MIN(Col1), Col2 FROM table GROUP BY Col2

otherwise, you will need another column, such as an incrementing uniqueid or a creation date.
