CREATE TABLE table_name_77 (total NUMBER, bronze VARCHAR2, rank VARCHAR2, gold VARCHAR2, silver VARCHAR2)

SELECT SUM(total) FROM table_name_77 WHERE gold < 4 AND silver > 0 AND rank = "3" AND bronze < 6
SELECT SUM("total") FROM "table_name_77" WHERE "3" = "rank" AND "bronze" < 6 AND "gold" < 4 AND "silver" > 0
