DDL, DML and DCL queries in SQL with its usage. How to use joining and different types of joining with suitable examples? Order by and group by commands with example queries. Sub queries and data integrity
This chapter covers the following:
- What is SQL
- Categories of SQL statements
- History of SQL
- Relational Database Structure
- MySQL Setup for practice
- SQL Basics (Lexical elements, Data types, Literals)
The purpose of the structured query language (SQL) is to store and process data in a relational database. Data in a relational database is often stored in tabular format, with rows and columns standing in for individual data properties and relationships between values. With SQL statements, you may enter data into a database, modify it, delete it, search it, and get it again. Burraq IT solutions provide SQL Training courses in Lahore Database performance can also be monitored and improved with the help of SQL.

Infographic Illustration on SQL operators.
SQL Operators are used to manipulate data within SQL statements. These operators can be categorized into several groups, including arithmetic operators, comparison operators, logical operators, and wildcard operators.
Arithmetic operators are used to perform mathematical operations on data, including addition (+), subtraction (-), multiplication (*), division (/), and modulo (%).
Comparison operators are used to compare values within SQL statements. These operators include equals to (=), not equals to (!= or <>), less than (<), greater than (>), less than or equal to (<=), and greater than or equal to (>=).
Logical operators are used to combine multiple conditions within SQL statements. These operators include AND, OR, and NOT.
Wildcard operators are used to search for specific patterns within data. These operators include the percent symbol (%), which represents any number of characters, and the underscore symbol (_), which represents a single character.
By using these operators, you can create powerful and complex SQL statements to manipulate data in various ways.

Computer Network Advantages Vs Disadvantages
On the basis of factors including such as Communication, Resource Sharing, File Sharing, Flexibility and Price which are really important to consider in this comparison.
A computer network is a group of interconnected devices, such as computers, servers, routers, switches, and other network-enabled devices, that communicate and share resources with each other. Computer networks can be categorized into two types, namely, local area network (LAN) and wide area network (WAN).

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.

3. WHAT ISSQL?
Structured QueryLanguage
SQL is Structured Query Language,
which is a computer langauge for
storing, manipulating, and retrieving
data stored in relational database.
SQL is the standard language for
Relation Database System. All
relational database management
systems like "MySQL, MS Access,
Oracle, Postgres and SQL Server" use
SQL as standard database language.
4. SQL
COMMANDS
DDL - Data Definition Language
DML - Data Manipulation Language
DCL - Data Control Language
DQL - Data Query Language
5. DATA DEFINITIONLANGUAGE
(DDL) COMMANDS
DDL(Data Definition Language): To make/perform changes to the
physical structure of any table residing inside a database, DDL is
used. These commands when executed are auto-commit in
nature and all the changes in the table are reflected and saved
immediately.
In SQL DDL commands are used to create and modify the
structure of a database and database objects. These commands
are CREATE, DROP, ALTER, TRUNCATE, and RENAME. Let us
discuss these commands one at a time.
6. DATA MANIPULATION
LANGUAGE (DML)COMMANDS
DML(Data Manipulation Language): Once the tables are created
and the database is generated using DDL commands,
manipulation inside those tables and databases is done using
DML commands. The advantage of using DML commands is, that
if in case any wrong changes or values are made, they can be
changed and rolled back easily.
DML is used for inserting, deleting, and updating data in a
database. It is used to retrieve and manipulate data in a
relational database. It includes INSERT, UPDATE, and DELETE.
Let's discuss these commands one at a time.
7. DATA CONTROL LANGUAGE
(DCL) COMMANDS
DCL(Data Control Language): DCL commands as the name
suggests manage the matters and issues related to the data
controller in any database. DCL includes commands such as
GRANT and REVOKE which mainly deal with the rights,
permissions, and other controls of the database system.
DCL is used to access the stored data. It is used to revoke and
grant the user the required access to a database. In the
database, this language does not have the feature of rollback. It
is a part of the structured query language (SQL).
8. DATA QUERY LANGUAGE
(DQL) COMMANDS
DQL(Data Query Language): Data query language consists of only
one command upon which data selection in SQL relies. The
SELECT command in combination with other SQL clauses is
used to retrieve and fetch data from databases/tables based on
certain conditions applied by the user.
DQL commands are used for fetching data from a relational
database. They perform read-only queries of data. The only
command, 'SELECT' is equivalent to the projection operation in
relational algebra. It command selects the attribute based on
the condition described by the WHERE clause and returns them.
