What are the best practices for defining primary keys and auto-increment values in SQLite database tables?

When defining primary keys in SQLite database tables, it is best practice to use an auto-incrementing integer column as the primary key. This ensures that each row in the table has a unique identifier, and the values are automatically generated as new rows are inserted. To define a primary key with auto-increment in SQLite, you can use the "INTEGER PRIMARY KEY AUTOINCREMENT" column type. 

CREATE TABLE example_table (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    column1 TEXT,
    column2 INTEGER
);
