To populate an SQLite database, you can follow these steps:
1. Create a database file: If you haven't already created an SQLite database file, you can use the following command in the terminal:
```
sqlite3 your_database_name.db
```
2. Create a table: You need to define the structure of your data by creating a table. For example, let's create a simple "users" table with two columns, "id" and "name":
```sql
CREATE TABLE users (
id INTEGER PRIMARY KEY,
name TEXT
);
```
3. Insert data into the table: Use the INSERT INTO statement to add rows of data to the table. Here's an example of inserting two users:
```sql
INSERT INTO users (id, name) VALUES (1, 'John');
INSERT INTO users (id, name) VALUES (2, 'Alice');
```
4. Verify the data: You can use the SELECT statement to retrieve the data from the table and verify if it has been populated correctly:
```sql
SELECT * FROM users;
```
5. Exit the SQLite prompt: Once you have finished populating your database, you can exit the SQLite prompt by typing ".exit" or pressing Ctrl + D.
Remember to replace "your_database_name.db" with the desired name for your database file. You can execute these SQL statements using an SQLite compatible client or by running them in a script using a programming language that supports SQLite, such as Python with the sqlite3 module.
