What is SQLite?

SQLite is a self-contained, serverless, zero-configuration, transactional database engine. It is embedded within the application and does not require a separate server process to operate. SQLite databases are stored as files on disk and can be easily transported between systems.

Creating a Database

To create a database in SQLite, you need to follow these steps:

1. Open the command prompt or terminal.
2. Type the following command to open the SQLite command-line shell and create a new database file:

   sqlite3 mydatabase.db
   

   Replace mydatabase.db with the desired name for your database file.

3. Press Enter, and SQLite will create the database file for you. You are now ready to start working with your database.

Creating Tables

After creating the database, you can begin creating tables to store your data. Each table represents an entity and consists of columns and rows. Here’s an example of how to create a table named users with columns for id, name, and email:

CREATE TABLE users (
  id INTEGER PRIMARY KEY,
  name TEXT,
  email TEXT
);

In this example, id is the primary key column, which ensures its uniqueness, and name and email are columns with the text data type.

Inserting Data

Once you have created the table, you can start inserting data into it. Here’s an example of how to insert a new row into the users table:

INSERT INTO users (name, email) VALUES ('John Doe', 'john@example.com');

You can replace the sample values with actual data.

Querying Data

To retrieve data from the database, you can use SQL SELECT statements. Here’s an example of how to select all rows from the users table:

SELECT * FROM users;

This query will fetch all columns from the users table.

Conclusion

SQLite offers a simple and efficient way to create and manage databases. By following the steps outlined in this tutorial, you can easily create a SQLite database, create tables, insert data, and query data. Utilizing SQLite’s lightweight and self-contained nature, you can incorporate database functionality into your applications without the need for a separate database server. Further exploration of SQLite’s features and capabilities will enable you to build robust and scalable applications.
