Solved in 5 steps
- Write the SQL code that will change the PROJ_NUM to 14 for employees who were hired before January 1, 1994, and whose job code is at least 501. (You may assume that the table will be restored to its condition preceding this question.)Toys Galore currently has a credit limit of 7,500. Because Toys Galore has an excellent credit rating, TAL Distributors is increasing the companys credit limit to 10,000. If yourun the SQL query in Exercise 1 after the credit limit has been increased, would ToysGalore still be included in the view? Why or why not?Consider the following schema and write SQL query for given statements. Student ( regNo, sName, sCity, sCGPA, sAge)Course ( cCode, cName, credit_hours)Enrollment (regNo, cCode, semester,quality_points,Grade) 1- Display 2nd row of Student table using Cursors. 2- Display all records of Enrollment table which are placed at even rows. 3- Execute given query in SQL and do as directed.a) UPDATE STUDENT SET ECITY = ‘ISB’ WHERE EID>101b) Count how many records have been updated in above query using cursor. 4- Write a mechanism which must not allow user to delete more than 1 records using cursor and transaction.
- Q1) Consider the employees database , where the primary keys are underlined. Give an expression in SQL for each of the following queries. Employee(ID. name, age, address, salary, departmet, position,ministry_name) Ministry(ministry_name, address,No_of _employee, No_of_dept., category) 1- Find all employees who live in baghdad and work in ministery of foreign affairs And older than all the employees who work in the consuls department. 2- Find the name of employees who work as a counselor in ministries that have more than 5 departments . 3- Insert a new employee (o the database.Using the relational database given in lab work no. 2, write the following queries in SQL: 4) How many instructors are advising more than three students?5) Which department has the highest number of students?6) Which courses have multiple prerequisites? Sort the list. ===================================== The relational database schemas are as follows:department(dept-name, building, budget)instructor(ID, name, dept-name, salary)student(ID, name, dept-name, tot-cred)advisor(s-ID, i-ID)course(course-id, title, dept-name, credits)teaches(ID, course-id, sec-id, semester, year)takes(ID, course-id, sec-id, semester, year, grade)classroom(building, room-number, capacity)time-slot(time-slot-id, day, start-time, end-time)section(course-id, sec-id, semester, year, building, room-number, time-slot-id)prereq(course-id, prereq-id)Using SQL data definition language, write the SQL statements to create each of the following relations. i. student(student id, name, dept id, total credits)ii. department(dept id, building, budget)iii. lecture_hall(hall id, campus, capacity)iv. course(course id, title, dept id, credits) v. takes(student id, course id, semester, year, grade)
- Provide SQL queries for tables: employees, departments,1. List the following details of each employee: employee number, last name, first name and salary.2. List employees who were hired in 1988.3. List the manager of each department with the following information:department number, department name, the manager's employee number,last name, first name, and start employment date.4. List all employees whose first name is "John" and whose last names begin with "B."5. List all employees in the Marketing department, including their employee number, last name, firstname, and salary.Consider the following relational schema and answer the following questions. User (email, name, address, householdSize) a. Express in relational algebra the query that finds all pairs of users where the two people both claim to have a household size 2 and have the same address and returns their names and the common address. b. Express the above query in SQL. c. Write in SQL the query that finds the users whose household size is at least 50% more than the average household size and returns their name and household size, sorted by household size. (Hint: decompose the problem into sub-problems, and you may use a view to capture an intermediate result.) d. Write in SQL the query that finds all users each having a household size different from the total number of users having the same address as him or her. (Hint: again, decompose the problem into sub-problems, and you may use a view to capture a intermediate result.)Answer the following questions according to the figure which shows the ERD(Entity Relationship Diagram) of the Hospital system: What is the command of SQL language used to delete the whole table?
