CREATE TABLE table_203_670 (id NUMBER, "pos" CLOB, "driver" CLOB, "entrant" CLOB, "constructor" CLOB, "time/retired" CLOB, "grid" NUMBER)

SELECT "entrant" FROM table_203_670 GROUP BY "entrant" ORDER BY COUNT("driver") DESC LIMIT 1
SELECT "entrant" FROM "table_203_670" GROUP BY "entrant" ORDER BY COUNT("driver") DESC FETCH FIRST 1 ROWS ONLY
