CREATE TABLE table_name_85 (goals_for NUMBER, wins VARCHAR2, goals_against VARCHAR2)

What is the smallest number of 'goals for' out of the clubs where there were 18 wins and fewer than 38 'goals against'?
SELECT MIN(goals_for) FROM table_name_85 WHERE wins = 18 AND goals_against < 38
SELECT MIN("goals_for") FROM "table_name_85" WHERE "goals_against" < 38 AND "wins" = 18
