CREATE TABLE table_name_56 (matches NUMBER, year VARCHAR2, wins VARCHAR2, losses VARCHAR2)

What is the number of matches when the wins are less than 8, and losses of 7, in 2011?
SELECT SUM(matches) FROM table_name_56 WHERE wins < 8 AND losses = 7 AND year = "2011"
SELECT SUM("matches") FROM "table_name_56" WHERE "2011" = "year" AND "losses" = 7 AND "wins" < 8
