Original relational-operation definitions

Determine the intended result of the printed SQL. EMP rows (EID, Ename, DNO, Salary): (11, John Bate, 1, 20000); (12, Mohammed Karim, 2, 40000); (13, Sadat Hossain, 1, 50000); (14, Katherine Li, 3, 20000); (15, Shuvashish Bose, 3, 40000). DEPT rows (DNO, Dname, Manager ID): (1, Admin, 11); (2, Accounts, 13); (3, Research, 15). DEPT_LOCS rows (DNO, Region): (1, L1); (1, L3); (2, L2); (3, L3); (3, L2). Literal printed SQL: SELECT EName, Salary FROM EMP WHERE DNO IN (( SELECT DNO FROM DEPT) MINUS (SELECT DNO FROM DEPT_LOCS WHERE Region=’L2’) )). Editorial clarification: the source has an extra closing parenthesis; the explanation distinguishes intended set-difference semantics from literal executable syntax.
