IS582 Week 5 Out-of-class Assignment As noted in class, I stress the importance of using your own words. Quotes are fine, but also make sure to explain in your own words. On this assignment, please answer the first two questions and at least one of the remaining three – three questions in all. 1. Briefly describe what a subquery is and how it works. Then offer an example which we might use with one of the databases we use in class. Subqueries involve nesting one SELECT statement within another. The nested SELECT is used as part of a condition in the WHERE clause of the first SELECT statement. The nested SELECT statement can return a set of records from one table, which is then used in a logical operator within the parent SELECT query. SELECT Student_ID FROM Student WHERE Student_ID IN (SELECT Student_ID FROM ) 2. Briefly describe what a join is and how it works. Then offer an example which we might use with one of the databases we use in class .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
