Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE races (driverId VARCHAR, raceId VARCHAR, YEAR VARCHAR)
TABLE: CREATE TABLE results (driverId VARCHAR, raceId VARCHAR, YEAR VARCHAR)

### Question ###
How many drivers did not participate in the races held in 2009?

### Accurate SQL ###

SELECT COUNT(DISTINCT driverId) FROM results WHERE NOT raceId IN (SELECT raceId FROM races WHERE YEAR <> 2009)
