SQL scripts for each question

I NEED HELP FOR QUESTIONS NUMBERS (5, 6, 7 , 8) Starting from "Insert following values into the Project table." the answers should be written in sql scripts

1. Create Database schema called ClassAssignment

Use ClassAssignment database for rest of the exercise.

2. Create a table called Project with the following columns:

project_num INT NOT NULL PRIMARY KEY

project_code CHAR(4)

project_title VARCHAR(45)

first_name VARCHAR(45)

last_name VARCHAR(45)

project_budget DECIMAL(5,2)

3. Modify project_num to auto_increment and also auto_increment starts from 10.

4. Modify project_budget datatype from decimal (5, 2) to (10, 2).

5. Insert following values into the Project table.

DO NOT insert project_num. Auto_increment should start from 10

project_code	project_title	first_name	last_name	project_budget
PC01	DIA	John	Smith	10000.99
PC02	CHF	Tim	Cook	12000.50
PC03	AST	Rhonda	Smith	8000.40

6. Create a table PayRoll with the following info:

employee_num INT PRIMARY KEY AUTO_INCREMENT

job_id INT NOT NULL

job_desc VARCHAR(40)

emp_pay DECIMAL (10,2)

7. Alter PayRoll table with the following, make sure to write each script separately.

1. Add constraint on emp_pay so that only value greater than 10,000 can be inserted.

ii. Add constraint on job_desc so that default value set to Data Analyst.

iii. Add column pay_date (DATE) after job_desc.

8. Add Foreign Key constraint in PayRoll table with job_id column referencing to project_num column in Project table.

9. Insert following values into PayRoll table. DO NOT insert employee_num and job_desc, those should be auto populated using auto_increment and default values, respectively.

job_id	pay_date	emp_pay
10	current date	12000.99
11	current date	14000.99
12	current date	16000.99

10. Update emp_pay in PayRoll table for employee_num = 2 with 10% emp_pay increase i.e. (emp_pay * 0.10).

11. Create Project_backup table from project table you created above using bulk insert statement only for last_name 'Smith'.

12. Create VIEW as PayRoll_View from PayRoll table you created above. However, your VIEW should only contain job_id, job_desc and pay_date for job_id > 10.

13. Create Index for pay_date on PayRoll table.

14. Delete all data from project_backup table but keep the table structure.

15. Write a DELETE script to delete a row from Project table where project_num = 10.

If there is an error, give a short explanation of what/why about error msg?

16. Solve the question 15 above without error, i.e. write a script how you can delete.
