What is SQL?

  • SQL stands for "Structured Query Language."
  • It is a domain-specific language used for managing and manipulating relational databases.
  • SQL provides a standardized way to interact with databases, enabling users to create, retrieve, update, and delete data.
  • It is widely employed for tasks such as database design, data querying, and data manipulation.
  • SQL is not limited to a specific database system and is supported by various database management systems (DBMS) like MySQL, PostgreSQL, Oracle, and Microsoft SQL Server.
  • Common SQL operations include SELECT (querying data), INSERT (adding new data), UPDATE (modifying existing data), and DELETE (removing data).

SQL Example:

-- Selecting data from a table
SELECT FirstName, LastName FROM Employees WHERE Department = 'IT';

-- Inserting new data
INSERT INTO Customers (CustomerID, CustomerName, Email) VALUES (1, 'ABC Company', 'abc@example.com');

-- Updating existing data
UPDATE Products SET Price = 29.99 WHERE ProductID = 101;

-- Deleting data
DELETE FROM Orders WHERE OrderID = 500;

Advantages of Using SQL:

  • Declarative Language: SQL is a declarative language, meaning users specify the result they want, and the database management system determines the best way to retrieve it.
  • Scalability: SQL databases can handle large amounts of data and scale well with the growth of data and users.
  • Data Integrity: SQL supports constraints and relationships, ensuring the integrity of data stored in the database.
  • Interoperability: SQL is supported by a wide range of database systems, promoting interoperability across different platforms.
