Learn MySQL from Basics to Advanced 🚀
This MySQL course covers databases, queries, joins, functions, indexing, and more. Perfect for beginners and advanced learners.
SQL stands for Structured Query Language.
It is used to communicate with relational databases.
SQL is a standard language approved by ANSI and ISO.
Used to create, retrieve, update, and delete (CRUD) data in databases.
Simple & Powerful – Easy to learn and use.
Declarative Language – You specify what you want, not how.
Portable – Works with all major databases (MySQL, SQL Server, Oracle, PostgreSQL, SQLite, etc.).
Secure – Provides access control via permissions and roles.
Supports Transactions – Ensures ACID properties (Atomicity, Consistency, Isolation, Durability).
SQL commands are divided into categories:
🔹 3.1 DDL – Data Definition Language
Used to define database schema (structure).
CREATE – Create database objects (table, view, etc.).
ALTER – Modify existing objects.
DROP – Delete objects.
TRUNCATE – Remove all records but keep structure.
RENAME – Rename objects.
🔹 3.2 DML – Data Manipulation Language
Used to manage data inside tables.
SELECT – Retrieve data.
INSERT – Add new data.
UPDATE – Modify data.
DELETE – Remove data.
🔹 3.3 DCL – Data Control Language
Used for access control.
GRANT – Give permissions.
REVOKE – Remove permissions.
🔹 3.4 TCL – Transaction Control Language
Used to manage transactions.
COMMIT – Save changes permanently.
ROLLBACK – Undo changes.
SAVEPOINT – Set checkpoints.
Different databases have variations, but common types are:
Numeric: INT, DECIMAL, FLOAT
String: CHAR, VARCHAR, TEXT
Date/Time: DATE, TIME, DATETIME, TIMESTAMP
Boolean: TRUE / FALSE
Arithmetic: +, -, *, /, %
Comparison: =, !=, <, >, <=, >=
Logical: AND, OR, NOT
Other: BETWEEN, IN, LIKE, IS NULL
Constraints ensure data integrity.
PRIMARY KEY – Uniquely identifies each row.
FOREIGN KEY – Links two tables.
UNIQUE – No duplicate values.
NOT NULL – Value cannot be empty.
CHECK – Condition must be true.
DEFAULT – Provides default value.
Used to combine rows from multiple tables.
INNER JOIN – Returns matching rows.
LEFT JOIN – All rows from left + matches.
RIGHT JOIN – All rows from right + matches.
FULL JOIN – All rows when there is a match in one.
CROSS JOIN – Cartesian product.
A view is a virtual table based on SQL query.
Used for simplification and security.
Example: CREATE VIEW employee_info AS SELECT name, salary FROM employees WHERE salary > 50000;
Indexes speed up searches in tables.
Types:
Clustered Index – Alters physical order of table.
Non-clustered Index – Creates separate structure.
Stored Procedure – Precompiled SQL code executed with parameters.
Function – Returns a single value.
Process of organizing data to avoid redundancy.
1NF – Atomic values.
2NF – No partial dependency.
3NF – No transitive dependency.
BCNF – Stronger version of 3NF.
Transaction – A sequence of operations treated as a single logical unit.
ACID:
Atomicity – All or nothing.
Consistency – Data remains valid.
Isolation – Transactions are independent.
Durability – Changes are permanent.
Aggregate Functions: COUNT(), SUM(), AVG(), MIN(), MAX()
String Functions: UPPER(), LOWER(), CONCAT(), SUBSTRING()
Date Functions: NOW(), DATEADD(), DATEDIFF(), CURDATE()
Triggers – Execute automatically on events.
Subqueries – Query inside another query.
CTE (Common Table Expressions) – Temporary result set.
Window Functions – Perform calculations across sets (ROW_NUMBER(), RANK()).
MySQL – Open-source, widely used.
PostgreSQL – Advanced, supports complex queries.
Oracle DB – Enterprise-level.
MS SQL Server – Microsoft’s RDBMS.
SQLite – Lightweight, file-based.
