SQL - Structured Query Language

What is SQL?

SQL, which stands for Structured Query Language, is a domain-specific programming language used for managing and manipulating relational databases. It is the foundation of most database management systems (DBMS) and serves as the primary means of communication between applications and databases. SQL enables users to interact with databases by defining, retrieving, updating, and managing data efficiently.

Key Components of SQL

1. Data Definition Language (DDL)

  • CREATE: This command is used to create database objects such as tables, indexes, and views.
  • ALTER: ALTER is employed to modify existing database structures, including adding, deleting, or modifying columns.
  • DROP: It allows users to delete database objects like tables, indexes, or views.

2. Data Manipulation Language (DML)

  • SELECT: SELECT is used to retrieve data from one or more tables.
  • INSERT: This command adds new rows of data into tables.
  • UPDATE: UPDATE is used to modify existing data in a table.
  • DELETE: DELETE removes rows from a table.

3. Data Control Language (DCL)

  • GRANT: GRANT gives specific privileges to database users or roles.
  • REVOKE: REVOKE removes privileges from users or roles.

4. Transaction Control Language (TCL)

  • COMMIT: COMMIT is used to save changes made during a transaction.
  • ROLLBACK: ROLLBACK reverses changes in a transaction.
