Question

Lets say I have a table describing cars with make, model, year and some other columns.

From that, I would like to get one full row of each make and model for latest year.

Or to put it in another way. Each row would have unique combination of make and model with other data from corresponding row with largest value of year.

Standard SQL solution would be great.

Answer 1

select t1.make, t1.model, t1.year, t1.other_cols from table t1 where year = (select max(year) from table t2               where t2.make = t1.make               and t2.model = t1.model              );
