Write Ten SQL SELECT statements to query the STUDENT schema you created for practice lab 2. Your Select Statements should run error-free and should be valid.

Submit two separate files: one plain text file (.txt or .sql file) with your SELECT statements only; and the other document (doc/docx/pdf) include both your SELECT statements and your query results (copy and paste text or screen shots). The instructor and TA should be able to run your plain text source file as script and generate the same output as shown in your result document.

  1. Show the number of students whose zip is 07070.
  2. List all students (display student_id, first name, last name, and employer) who live in Columbus, OH.
  3. Show the zip, state and city that have > 5 students as residents.
  4. List all students (display student_id, first name, last name, and registration date) who registered on or before 2/13/2007 but have not enrolled in any course.
  5. Show the number of students enrolled in the ‘Intro to Unix’ course.
  6. List all students (display student_id, first name, last name, and employer) who took courses taught by instructor ‘Anita Morris’.
  7. List all distinct courses (display instructor name, course_no and description) taught by ‘Anita Morris’.
  8. For all students who took ‘Intro to Unix’, calculate the highest, lowest, and average midterm exam grade.
  9. Show which courses have > 10 students enrolled. Display course_no, description and number of students enrolled.
  10. List any student who has enrolled in the same course multiple times. Display student name, course description, and enrollment count.

1)Consider the following schema:Suppliers(sid: integer, sname: string, address: string, country: string)Parts(pid: integer, pname: string, color: string, weight: real)Catalog(sid: integer, pid: integer, cost: real)The Catalog relation lists the prices charged for parts by Suppliers. Write the following queriesin SQL:1. Write SQL statements to create these tables with the proper primary key and foreignkey constraints2. Find the snames of all Chinese suppliers3. Find the pnames of parts supplied by American suppliers4. Find the pnames of parts for which there is some supplier.5. Find the pnames of green parts that are not supplied by Italian suppliers.6. Find the snames of suppliers who supply every part.7. Find the snames of suppliers who supply every red part.8. Find the pnames of parts supplied by Acme Widget Suppliers and no one else.9. Find the sids of suppliers who charge more for some part than the average cost ofthat part (averaged over all the suppliers who supply that part).10.For each part, find the sname of the supplier who charges the most for that part.11. Find the sids of suppliers who supply only red parts.12.Find the sids of suppliers who supply a red part and a green part.13.Find the sids of suppliers who supply a red part or a green part.14.Find the average weight of red parts for suppliers from each country that has at least 2suppliers.15.For every supplier that only supplies green parts, print the name of the supplier and thetotal number of parts that she supplies.16.For every supplier that supplies a green part and a red part, print the name and price ofthe most expensive part that she supplies.

Create a 9 pages page paper that discusses the project risk profile. This essay stresses that the protocol produces meaningful project profiles using a consistent approach and fully quantifying concepts which might be considered non-quantifiable. Importantly, this protocol allows for the assessment of risks and strategic factors which are important for good decision-making. The PRP and SI are somewhat subjective calculations, and the FAP protocol forces management and appraisal teams to consider reasonable values for important, subjective judgments.

This paper makes a conclusion that management will reject projects outright if the risks are too great or if the projects do not fit with the company’s overall strategic vision, but using the FAP protocol allows for a full understanding of financial and strategic potentials. Aspects of projects such as deferment, growth or abandonment are important considerations, and the FAP protocol structure allows evaluation teams to include those aspects in the evaluations. Since several sub-models play into the overall structure of the FAP model, evaluators are afforded flexibility. No project is rejected based on a single aspect of consideration, nor are projects accepted which may produce undesirable results because strategy and risk were not accounted for during assessment. The FAP model produces a dynamic and pragmatic approach to capital project evaluations and allows the management and appraisal teams to introduce their judgments into the model in a straightforward and structured way.
