What are the different ids and stop durations of all the drivers whose stop lasted longer than the driver in the race with the id 841?
SELECT DISTINCT driverid ,  STOP FROM pitstops WHERE duration  >  (SELECT min(duration) FROM pitstops WHERE raceid  =  841)
drivers whose stop lasted longer than another driver refers to duration > (subquery); stop duration refers to duration; different ids refers to DISTINCT driverid;
