Schema: CREATE TABLE files (f_id VARCHAR, duration VARCHAR); CREATE TABLE song (resolution INTEGER, f_id VARCHAR)
Question: What are the maximum and minimum resolution of songs whose duration is 3 minutes?
SQL: SELECT MAX(T2.resolution), MIN(T2.resolution) FROM files AS T1 JOIN song AS T2 ON T1.f_id = T2.f_id WHERE T1.duration LIKE "3:%"
