In this example, we will pretend that the student table in the university database is indexed by StudentID (the primary key), Major, Age, MaritalStatus, and HomeZipCode (all secondary keys). Let's pretend a university needed a list of students from the 45462 zip code who are either above the age of 25, married, and majoring in MIS or computer science OR who are under the age of 25 and majoring in computer engineering. Is there a way to use indexes to restrict results to to those entries that fulfill this condition?

If yes, what might be the potential security risk andhow would you fix the problem by setting up the VPD appropriately?
Consider the query:select *from r, swhere upper(r.A) = upper(s.A);where “upper” is a function that returns its input argument with all lowercaseletters replaced by the corresponding uppercase letters. Some database systems would use a (block) nested-loop join for this query, which can be very inefficient. Briefly explain how hash-join or merge-join can be used for this query.
