CREATE TABLE table_name_73 (goals_against NUMBER, goals_for VARCHAR2, points VARCHAR2, wins VARCHAR2)

How many goals against were scored when the points were smaller than 13, the wins were smaller than 3, and the goals for were smaller than 15?
SELECT SUM(goals_against) FROM table_name_73 WHERE points < 13 AND wins < 3 AND goals_for < 15
SELECT SUM("goals_against") FROM "table_name_73" WHERE "goals_for" < 15 AND "points" < 13 AND "wins" < 3
