CREATE TABLE driverstandings (driverid VARCHAR, points VARCHAR, position VARCHAR, wins VARCHAR)
CREATE TABLE drivers (forename VARCHAR, driverid VARCHAR)

Find all the forenames of distinct drivers who won in position 1 as driver standing and had more than 20 points?
SELECT DISTINCT T1.forename FROM drivers AS T1 JOIN driverstandings AS T2 ON T1.driverid = T2.driverid WHERE T2.position = 1 AND T2.wins = 1 AND T2.points > 20
SELECT DISTINCT "T1"."forename" FROM "drivers" AS "T1" JOIN "driverstandings" AS "T2" ON "T1"."driverid" = "T2"."driverid" AND "T2"."points" > 20 AND "T2"."position" = 1 AND "T2"."wins" = 1
