    【Question】
    How many points did Lewis Hamilton get in total in all the Formula_1 races he participated?

    【Evidence】
    

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT SUM(T2.points) FROM drivers AS T1 INNER JOIN results AS T2 ON T1.driverId = T2.driverId WHERE T1.forename = 'Lewis' AND T1.surname = 'Hamilton'
