To install and use SQLite, you can follow these steps:

  1. Download SQLite: Precompiled binary files for your operating system can be downloaded from the official SQLite website. Download link: https://www.sqlite.org/download.html
  2. Install SQLite: Unzip the downloaded SQLite binary file into the directory of your choice.
  3. Add SQLite to the environment variable (optional): To make it convenient to use the SQLite command line tool, you can add the directory where SQLite is located to the system’s environment variable. This allows you to use the SQLite command directly from any location.
  4. Open the command line interface: On Windows, you can press the Win + R keys, type “cmd,” and then press Enter to open the command prompt. On Mac, you can search and open the terminal using Spotlight.
  5. To run SQLite, simply type “sqlite3” in the command line interface and press Enter. If you have added SQLite to the environment variables, you can run the “sqlite3” command from any location.
  6. To create a database: In the SQLite command line, you can use the “CREATE DATABASE” statement to create a new database. For example, to create a database named “mydatabase.db”, you can enter the following command.
CREATE DATABASE mydatabase.db;
  1. To use a database: In the SQLite command line, you can open a previously created database by using the following command.
.open mydatabase.db
  1. To create a table: In SQLite command line, you can use the “CREATE TABLE” statement to create a new table. For example, to create a table named “users” with columns “id” and “name”, you can enter the following command:
CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT);
  1. Insert data: In the SQLite command line, you can use the “INSERT INTO” statement to insert data into a table. For example, to insert a record into the “users” table, you can enter the following command:
INSERT INTO users (id, name) VALUES (1, 'John');
  1. Data query: In SQLite command line, you can use the “SELECT” statement to retrieve data. For example, to query all records in the “users” table, you can enter the following command:
SELECT * FROM users;

These are the basic methods used with SQLite. You can also further study advanced features of SQLite such as indexes, constraints, joins, etc.
