CREATE TABLE table_name_70 (silver INT, gold VARCHAR, total VARCHAR, bronze VARCHAR)

What's the sum of Silver with total smaller than 560, a Bronze larger than 6, and a Gold of 3?
SELECT SUM(silver) FROM table_name_70 WHERE total < 560 AND bronze > 6 AND gold = 3
SELECT SUM("silver") FROM "table_name_70" WHERE "bronze" > 6 AND "gold" = 3 AND "total" < 560
