CREATE TABLE architect (Id VARCHAR(255)); CREATE TABLE mill (name VARCHAR(255), architect_id VARCHAR(255)); CREATE TABLE bridge (architect_id VARCHAR(255), length_meters INTEGER)
What are the distinct name of the mills built by the architects who have also built a bridge longer than 80 meters?
    
SQL: SELECT DISTINCT T1.name FROM mill AS T1 JOIN architect AS t2 ON T1.architect_id = T2.id JOIN bridge AS T3 ON T3.architect_id = T2.id WHERE T3.length_meters > 80
