Table schema:
CREATE TABLE DEPARTMENT (DName VARCHAR, DNO VARCHAR); CREATE TABLE MINOR_IN (DNO VARCHAR); CREATE TABLE DEPARTMENT (DName VARCHAR)

Question: Find the name of the department that has no students minored in?
SQL: SELECT DName FROM DEPARTMENT EXCEPT SELECT T1.DName FROM DEPARTMENT AS T1 JOIN MINOR_IN AS T2 ON T1.DNO = T2.DNO
