SQL is a relational database language used to define, manipulate, and control access to data in a relational database. SQL statements are used to perform tasks like data retrieval, insertion, deletion, updating and table/database management. The basic structure of an SQL query involves selecting data from one or more tables to display or use. SQL supports features like constraints, indexes, views, triggers that enforce data integrity and security.
Database Testing involves the testing of database triggers and logical views which are going to support database refactoring. It performs module testing of database functions, triggers, views, SQL queries etc. It validates database tables, data models, database schema etc. It checks rules of Referential integrity.
This is a word file for SQL COMMANDS and including some basic information regarding SQL. I hope it will help you a lot while doing SQL and its functions and commands.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

11. Default For example, if we create a table as below: CREATE TABLE Student (Student_ID integer Unique, Last_Name varchar (30), First_Name varchar (30), Score DEFAULT 80); and execute the following SQL statement, INSERT INTO Student (Student_ID, Last_Name, First_Name) values ('10','Johnson','Rick'); The table will look like the following: Even though we didn't specify a value for the "Score" column in the INSERT INTO statement, it does get assigned the default value of 80 since we had already set 80 as the default value for this column. Student_ID Last_Name First_Name Score 10 Johnson Rick 80
12. Unique For example, in the following CREATE TABLE statement, CREATE TABLE Customer (SID integer Unique, Last_Name varchar (30), First_Name varchar(30)); column "SID" has a unique constraint, and hence cannot include duplicate values. Such constraint does not hold for columns "Last_Name" and "First_Name". So, if the table already contains the following rows: Executing the following SQL statement, INSERT INTO Customer values ('3','Lee','Grace'); will result in an error because '3' already exists in the SID column, thus trying to insert another row with that value violates the UNIQUE constraint. SID Last_Name First_Name 1 Johnson Stella 2 James Gina 3 Aaron Ralph
13.
14. Primary Key A primary key is used to uniquely identify each row in a table. A primary key can consist of one or more fields on a table. When multiple fields are used as a primary key, they are called a composite key. CREATE TABLE Customer (SID integer PRIMARY KEY, Last_Name varchar(30), First_Name varchar(30));
15. Foreign Key A foreign key is a field (or fields) that points to the primary key of another table. The purpose of the foreign key is, only values that are supposed to appear in the database are permitted. CREATE TABLE ORDERS (Order_ID integer primary key, Order_Date datetime, Customer_SID integer references CUSTOMER(SID), Amount double); In the above example, the Customer_SID column in the ORDERS table is a foreign key pointing to the SID column in the CUSTOMER table.

20. Using SQL SQL statements can be embedded into a program (cgi or perl script, Visual Basic, C#, MS Access) OR SQL statements can be entered directly at the command prompt of the SQL software being used (such as mySQL)
21. Using SQL To begin, you must first CREATE a database using the following SQL statement: CREATE DATABASE database_name Depending on the version of SQL being used the following statement is needed to begin using the database: USE database_name

24. Using SQL SELECT auth_name, auth_city FROM publishers If you only want to display the author’s name and city from the following table: auth_id auth_name auth_city auth_state 123456789 Jane Doe Dearborn MI 000000001 John Smith Taylor MI auth_name auth_city Jane Doe Dearborn John Smith Taylor
25. Using SQL DELETE from authors WHERE auth_name=‘John Smith’ To delete data from a table, use the DELETE statement: auth_id auth_name auth_city auth_state 123456789 Jane Doe Dearborn MI 000000001 John Smith Taylor MI
26. Using SQL UPDATE authors SET auth_name=‘hello’ To Update information in a database use the UPDATE keyword Hello Hello Sets all auth_name fields to hello auth_id auth_name auth_city auth_state 123456789 Jane Doe Dearborn MI 000000001 John Smith Taylor MI
27. Using SQL ALTER TABLE authors ADD birth_date datetime null To change a table in a database use ALTER TABLE. ADD adds a characteristic. ADD puts a new column in the table called birth_date Type Initializer auth_id auth_name auth_city auth_state 123456789 Jane Doe Dearborn MI 000000001 John Smith Taylor MI birth_date . .
28. Using SQL ALTER TABLE authors DROP birth_date To delete a column or row, use the keyword DROP DROP removed the birth_date characteristic from the table auth_id auth_name auth_city auth_state 123456789 Jane Doe Dearborn MI 000000001 John Smith Taylor MI auth_state . .
29. Using SQL DROP DATABASE authors The DROP statement is also used to delete an entire database. DROP removed the database and returned the memory to system auth_id auth_name auth_city auth_state 123456789 Jane Doe Dearborn MI 000000001 John Smith Taylor MI
30. Normalization The process of removing redundant data by creating relations between tables is known as Normalization. Normalization process uses formal methods to design the database in interrelated tables.
Frequently, presenters must deliver material of a technical nature to an audience unfamiliar with the topic or vocabulary. The material may be complex or heavy with detail. To present technical material effectively, use the following guidelines from Dale Carnegie Training®. Consider the amount of time available and prepare to organize your material. Narrow your topic. Divide your presentation into clear segments. Follow a logical progression. Maintain your focus throughout. Close the presentation with a summary, repetition of the key steps, or a logical conclusion. Keep your audience in mind at all times. For example, be sure data is clear and information is relevant. Keep the level of detail and vocabulary appropriate for the audience. Use visuals to support key points or steps. Keep alert to the needs of your listeners, and you will have a more receptive audience.
In your opening, establish the relevancy of the topic to the audience. Give a brief preview of the presentation and establish value for the listeners. Take into account your audience’s interest and expertise in the topic when choosing your vocabulary, examples, and illustrations. Focus on the importance of the topic to your audience, and you will have more attentive listeners.
If you have several points, steps, or key ideas use multiple slides. Determine if your audience is to understand a new idea, learn a process, or receive greater depth to a familiar concept. Back up each point with adequate explanation. As appropriate, supplement your presentation with technical support data in hard copy or on disc, e-mail, or the Internet. Develop each point adequately to communicate with your audience.
