Question

Suppose I have

 +----------+--------+-----------+
 |  RACE_ID |  NAME  | POSITION  |
 +----------+--------+-----------+

With primary key

 +----------+--------+
 |  RACE_ID |  NAME  |
 +----------+--------+

For a given competitor, I would like to display the name plus the winner of the race. The winner of the race is whoever has POSITION=1 for the given RACE_ID. So something like the following

SELECT NAME, (???) AS WINNER where NAME='Thorpe'

I’m not sure what goes in ???. I’m using Postgres.

Answer 1

assuming the table name is contestant, I’d try something like this below :

SELECT con.NAME, win.NAME AS WINNER
  from contestant con
  join contestant win
    on win.race_id = con.race_id
   and win.position = 1
 where con.NAME='Thorpe'
