How to manage permissions in SQLite?

The main method of managing permissions in SQLite is by using the built-in access control statements and user management features. Here are some common permission management methods:

  1. Create a user: By using the CREATE USER statement, you can create a new user and specify their password and permissions.
CREATE USER 'username' IDENTIFIED BY 'password';
  1. Authorize users: With the GRANT statement, users can be authorized to operate on specified databases and tables.
GRANT SELECT, INSERT, UPDATE, DELETE ON table_name TO 'username';
  1. Revoke permission: The REVOKE statement can be used to revoke a user’s access privileges to a database and tables.
REVOKE SELECT, INSERT, UPDATE, DELETE ON table_name FROM 'username';
  1. To view user permissions: You can check a user’s permission information using the SHOW GRANTS statement.
SHOW GRANTS FOR 'username';
  1. Change password: The ALTER USER statement can be used to modify a user’s password.
ALTER USER 'username' IDENTIFIED BY 'new_password';
  1. Delete user: You can remove a specific user by using the DROP USER statement.
DROP USER 'username';

It is important to note that SQLite’s permission management function is relatively simple, primarily used to control user access to the database and tables. For more complex permission management functions, it is recommended to consider using other database management systems such as MySQL or PostgreSQL.
