CREATE TABLE table_204_737 (id NUMBER, "year" NUMBER, "order" CLOB, "quantity" NUMBER, "ger nos." CLOB)

were there more n31 or e34 ordered ?
SELECT "order" FROM table_204_737 WHERE "order" IN ('n31', 'e34') ORDER BY "quantity" DESC LIMIT 1
SELECT "order" FROM "table_204_737" WHERE "order" IN ('n31', 'e34') ORDER BY "quantity" DESC FETCH FIRST 1 ROWS ONLY
