Question: What is the constructor reference name of the champion in the 2009 Singapore Grand Prix? Please give its website.
Evidence: the time of the champion shows in the format of "minutes: seconds.millionsecond" in which Max(time); constructor reference name refers to constructorRef; website refers to url
Answer: Sorry, I cannot answer.
Permission: denied (Missing column permissions: results: raceId, time)
Gold SQL: SELECT T3.constructorRef, T3.url FROM results AS T1 INNER JOIN races AS T2 on T1.raceId = T2.raceId INNER JOIN constructors AS T3 on T1.constructorId = T3.constructorId WHERE T2.name = 'Singapore Grand Prix' AND T2.year = 2009 AND T1.time LIKE '_:%:__.___'
