Question Description
Suppose we wish to find the ID’s of the employees that are managed by people who are managed by the employee with ID 123. Here are two possible queries:I.SELECT ee.empID FROM Emps ee, Emps ff WHERE ee.mgrID = ff.empID AND ff.mgrID = 123;II.SELECT empID FROM Emps WHERE mgrID IN (SELECT empID FROM Emps WHERE mgrID = 123);Q. Which, if any, of the two queries above will correctly (in SQL2) get the desired set of employee ID’s?a)Both I and IIb)I onlyc)II onlyd)Neither I nor ICorrect answer is option 'A'.
