PDOException: SQLSTATE[01000]: Warning: 1265 Data truncated for column 'max_score' at row 3: UPDATE {quiz_node_properties} SET max_score=max_score_for_random * number_of_random_questions + ( SELECT SUM(max_score) FROM {quiz_node_relationship} qnr WHERE qnr.question_status = 1 AND parent_vid = quiz_node_properties.vid) WHERE (vid IN (:db_condition_placeholder_0)) ; Array ( [:db_condition_placeholder_0] => 242 ) in quiz_update_max_score_properties() (line 2574 of /sites/all/modules/contrib/quiz/quiz.module).
