  SELECT * FROM users;
  This query will retrieve all rows and columns from the "users" table.
• INSERT: The INSERT query is used to add new rows to a database table. For example:
  INSERT INTO users (name, email) VALUES ('John', 'john@example.com');
  This query will insert a new row into the "users" table, with the name "John" and the email "john@example.com".
• UPDATE: The UPDATE query is used to modify existing rows in a database table. For example:
  UPDATE users SET name='Jane' WHERE email='john@example.com';
  This query will update the name of the user with the email "john@example.com" to "Jane".
• DELETE: The DELETE query is used to delete rows from a database table. For example:
  DELETE FROM users WHERE email='john@example.com';
