Program node ./bin/www exited with code 1

connection.query('INSERT INTO users (user_id, password) VALUES (?, password(?))', user_id, password, 
function(err, result) {
    console.log(result);
  });

위와 같이 작성하면 에러가 납니다.

connection.query('INSERT INTO users (user_id, password) VALUES (?, password(?))', [user_id, password], 

function(err, result) {
    console.log(result);
  });

위와 같이 작성해야 맞습니다.
