1. Let us consider the following relational database. - Professors (id, fName, IName, ssn, email) -
Students (id, JName, IName, dob, gpa, email) - TeachesCourses(number, sectionNo, semester,
creditHrs, title, profID) - CompLanguages(studentil complanguage) - Enrolls(studentID number,
sectionNo, semester, courseGrade) - Use(iradingschema(number sectionNo, semester cutoff
letter(irade) - HasGradingCategoriess (category, weight, mumber, sectionNo, semester) -
Gradingactivites (categord Litle, maxPoints) - Submit(studentID, category, title point) The primary
key for each relation is underlined. The foreign keys for this database are as follows: - the column
proflD of relation TeachesCourses that references table Professors, - the column studentID of
relation CompLanguages that relerences table Students, - the column studentID of relation Enrolls
that references table Students, - the columns number, sectionNo, semester of relation Enrolls that
references table TeachesCourses, - the columns number, sectionNo, semester of relation
UseGradingSchema that references table TeachesCourses, - the columns number, sectionNo,
semester of relation HasGradingCategoriess that references table TeachesCourses, - the column
category of relation GradingActivites that references table HasGradingCategoriess. - the column
studentiD of relation Submits that references table Students, and - the columns category and tile
of relation Submits that references table GradingActivites Task: Write exactly one SQL statement
for the following question. Also, the query answers must not contain duplicates, but you should
use the SQL keyword distinct only when necessary. Use ecLab.sql to test your code, and its
output should be like the one listed here. Otherwise. your SQL code has a logic error(s). Q:
