Hi,

Got this table

Model Price Column 3 Column 4 Column 5 etc
A3 123 x x x
A3 198 x x x
A3 225 x x x
A4 234 x x x
A4 227 x x x
A5 121 x x x
A5 234 x x x
A5 232 x x x

I want to return 1 row for each distinct model with the lowest price. I believe I can user OVER PARTITION but not sure how. Thanks

from (
select model, price, col3, col4, col5, row_number() over (partition by model order by price desc) AS recID
from table) as f
where recid = 1
