SQL stands for Structured Query Language.
It is a standard language used to work with databases.
SQL helps developers communicate with a database in a structured and controlled way.
Using SQL, we can read data, insert new data, modify existing data, and remove unwanted records.
Every modern application such as websites, mobile apps, and software systems uses SQL to handle data.
The SELECT command is one of the most important SQL statements.
It is used whenever we want to read data from a database table.
The star symbol means all columns stored in the table.
The table name tells SQL from where the data should be fetched.
Instead of selecting all columns, SQL also allows us to fetch specific columns.
This helps reduce unnecessary data and improves performance.
In real applications, developers rarely fetch all columns at once.
Only required data is selected based on the screen or feature.
Database tables store information in rows and columns.
Each row represents a single record.
Each column represents a specific type of data.
SQL works directly with these tables to manage structured information efficiently.
SQL queries are written in simple English-like commands.
This makes SQL easy to read, understand, and maintain.
Because of its simplicity and power, SQL is used by backend developers, full stack developers, and data professionals worldwide.
