CREATE TABLE table_name_91 (area__km_2__ INT, code VARCHAR, region VARCHAR)

What is the average area larger than Code 19025 but a smaller region than 12?
SELECT AVG(area__km_2__) FROM table_name_91 WHERE code > 19025 AND region < 12
SELECT AVG("area__km_2__") FROM "table_name_91" WHERE "code" > 19025 AND "region" < 12
