CREATE TABLE table_name_31 (geohash_length NUMBER, lng_error VARCHAR2, lng_bits VARCHAR2)

What is the highest geohash length when there is a ng error of 0.00017, and a lng bits smaller than 20?
SELECT MAX(geohash_length) FROM table_name_31 WHERE lng_error = "±0.00017" AND lng_bits < 20
SELECT MAX("geohash_length") FROM "table_name_31" WHERE "lng_bits" < 20 AND "lng_error" = "±0.00017"
