CREATE TABLE table_name_65 (longitude NUMBER, diameter__km_ VARCHAR2, latitude VARCHAR2)

Tell me the sum of longitude for diameter being 22.6 and latitude less than -12.4
SELECT SUM(longitude) FROM table_name_65 WHERE diameter__km_ = 22.6 AND latitude < -12.4
SELECT SUM("longitude") FROM "table_name_65" WHERE "diameter__km_" = 22.6 AND "latitude" < -12.4
