What is SQL (Structured Query Language)?

SQL (Structured Query Language) is the standard language used to communicate with relational databases. It allows you to store, retrieve, update, and delete data efficiently. SQL is used with database systems such as Microsoft SQL Server, MySQL, Oracle, and PostgreSQL.

Using SQL, you can perform tasks like:

  • Retrieve data using the SELECT statement
  • Insert new records using INSERT
  • Update existing records using UPDATE
  • Delete records using DELETE
  • Filter data using the WHERE clause
  • Sort data using ORDER BY
  • Combine data from multiple tables using JOIN

SQL is one of the most important skills for developers, database administrators, and data analysts.

At DotNetGurukul, you'll learn SQL from the basics with practical examples and hands-on exercises, helping you build a strong foundation in database programming.
