CREATE TABLE table_name_72 (goal_difference NUMBER, played VARCHAR2, goals_against VARCHAR2, position VARCHAR2)

What is the highest Goal Difference when the goals against were less than 76, and the position larger than 5, and a Played larger than 30?
SELECT MAX(goal_difference) FROM table_name_72 WHERE goals_against < 76 AND position > 5 AND played > 30
SELECT MAX("goal_difference") FROM "table_name_72" WHERE "goals_against" < 76 AND "played" > 30 AND "position" > 5
