CREATE TABLE table_name_81 (goals_for NUMBER, goal_difference VARCHAR2, points VARCHAR2, goals_against VARCHAR2)

What is the average number of goals with more than 9 points, less than 14 goals against, and a goal difference less than 17?
SELECT AVG(goals_for) FROM table_name_81 WHERE points > 9 AND goals_against < 14 AND goal_difference < 17
SELECT AVG("goals_for") FROM "table_name_81" WHERE "goal_difference" < 17 AND "goals_against" < 14 AND "points" > 9
