CREATE TABLE table_name_75 (longitude NUMBER, water__sqmi_ VARCHAR2, ansi_code VARCHAR2)

what is the longitude when the water (sqmi) is 0.317 and the ansi code is higher than 1759695?
SELECT AVG(longitude) FROM table_name_75 WHERE water__sqmi_ = 0.317 AND ansi_code > 1759695
SELECT AVG("longitude") FROM "table_name_75" WHERE "ansi_code" > 1759695 AND "water__sqmi_" = 0.317
