Question

I have the following SQL:

select code, distance from places;    

The output is below:

CODE      DISTANCE
106     386.895834130068
80      2116.6747774121 
80      2117.61925131453
106     2563.46708627407

I want to be able to just get a single code and the closest distance. So I want it to return this:

CODE      DISTANCE
106     386.895834130068
80      2116.6747774121

Still playing with Distinct and Group By.

Answer 1

select `code`, min(distance) as minimal_distance
from places
group by `code`
