CREATE TABLE table_name_72 (length__m_ INT, country VARCHAR, maximum_grade___percentage_ VARCHAR, vertical_drop__m_ VARCHAR)

What is the shortest length of a track in Norway that has a maximum grade of 15% and a vertical drop less than 122.22 m?
SELECT MIN(length__m_) FROM table_name_72 WHERE maximum_grade___percentage_ = "15" AND vertical_drop__m_ < 122.22 AND country = "norway"
SELECT MIN("length__m_") FROM "table_name_72" WHERE "15" = "maximum_grade___percentage_" AND "country" = "norway" AND "vertical_drop__m_" < 122.22
