CREATE TABLE table_7441 ("geohash length" FLOAT, "lat bits" FLOAT, "lng bits" FLOAT, "lat error" TEXT, "lng error" TEXT, "km error" TEXT)

What is the highest geohash length when the lat error is 0.00068, and the lat bits larger than 17?
SELECT MAX("geohash length") FROM table_7441 WHERE "lat error" = '±0.00068' AND "lat bits" > '17'
SELECT MAX("geohash length") FROM "table_7441" WHERE "lat bits" > '17' AND "lat error" = '±0.00068'
