I've created a table with a primary key and enabled AUTO_INCREMENT, how do I get MYSQL use AUTO_INCREMENT?

CREATE TABLE IF NOT EXISTS test.authors (
    hostcheck_id INT PRIMARY KEY AUTO_INCREMENT,
    instance_id INT,
    host_object_id INT,
    check_type INT,
    is_raw_check INT,
    current_check_attempt INT,
    max_check_attempts INT,
    state INT,
    state_type INT,
    start_time datetime,
    start_time_usec INT,
    end_time datetime,
    end_time_usec INT,
    command_object_id INT,
    command_args VARCHAR(25),
    command_line VARCHAR(100),
    timeout int,
    early_timeout INT,
    execution_time DEC(18,5),
    latency DEC(18,3),
    return_code INT,
    output VARCHAR(50),
    long_output VARCHAR(50),
    perfdata VARCHAR(50)
);

Here is the query I used, I've tried "" and "1" for the first value but it doesn't work.

INSERT INTO  test.authors VALUES ('1','1','67','0','0','1','10','0','1',
'2012-01-03 12:50:49','108929','2012-01-03 12:50:59','198963','21','',
'/usr/local/nagios/libexec/check_ping  5','30','0','4.04159','0.102','1',
'PING WARNING -DUPLICATES FOUND! Packet loss = 0%, RTA = 2.86 ms','',
'rta=2.860000m=0%;80;100;0');

Set the auto increment field to NULL or 0 if you want it to be auto magically assigned...
