The table STUDENT has the attributes STUDENT_ID, NAME, SCHOOL_ID, and ADDR. The table SCHOOL has the attributes SCHOOL_ID, NAME, and STATE_CODE. Assume that there is a 1:N relation between SCHOOL and STUDENT. Which of the following creates a table that shows the STUDENT attributes and the corresponding SCHOOL attributes? a. SELECT * SCHOOL_ID FROM STUDENT JOIN SCHOOL b. SELECT * SCHOOL_ID FROM STUDENT JOIN SCHOOL USING(SCHOOL_ID) c. SELECT * SCHOOL_ID FROM STUDENT NATURAL JOIN SCHOOL d. SELECT * SCHOOL_ID FROM STUDENT, SCHOOL WHERE SCHOOL_ID = SCHOOL_ID

(Choose all of the correct superkeys.) Find all superkeys of the DEPARTMENT relation. Its primary key (PK) is underlined. DEPARTMENT (number, dname, mgrssn, location) PK = {dname, location} {number} {number, dname} {number, dname, mgrssn} {number, dname, mgrssn, location} {dname} {dname, mgrssn} {dname, mgrssn, location} {mgrssn} {mgrssn, location} {location} {number, dname, mgrssn} {number, dname, location} {number, mgrssn} {number, mgrssn, location} {number, location} {dname, location}
SQL allows a foreign-key dependency to refer to the same relation, as in the following example: create table manager (employee name char(20), manager name char(20), primary key employee_name, foreign key (manager name) references manager on delete cascade) Here, employee name is a key to the table manager, meaning that each em- ployee has at most one manager. The foreign-key clause requires that every manager also be an employee. Explain exactly what happens when a tuple in the relation manager is deleted.
Given the following relations (the primary keys are underlined): MATCH (CodM, Home Team VisitingTeam, Date,League) PLAYER (CodP, Name, Surname, Role, Nation, Team) GOAL (CodP, CodM, MinutesIntoTheMatch) YELIOW-CARDS (CodP, CodM, MinutesIntoTheMatch) Please note that MinutesIntoTheMatch indicates the time at which either the goal was scored or the yellow card was cautioned (e.g.. between 1st and 90th). Write SQL Query for each match in which no more than 2 players playing as defender (role= Defender) were cautioned with a yellow card, show match code date on which the match was held, and total number of goals scored by each player
