Table schema:
CREATE TABLE table_name_4 (silver INTEGER, rank VARCHAR, gold VARCHAR, total VARCHAR, bronze VARCHAR)

Question: What is the least silver when the total is more than 2, bronze is 3, gold is more than 0, and rank is 1?
SQL: SELECT MIN(silver) FROM table_name_4 WHERE total > 2 AND bronze = 3 AND gold > 0 AND rank = "1"
