  #
  #   db = DuckDB::Database.open # database in memory
  #   con = db.connect
  #
  #   con.query('CREATE TABLE users (id INTEGER, name VARCHAR(30))')
  #
  #   con.query("INSERT into users VALUES(1, 'Alice')")
  #   con.query("INSERT into users VALUES(2, 'Bob')")
  #   con.query("INSERT into users VALUES(3, 'Cathy')")
  #
  #   result = con.query('SELECT * from users')
  #   result.each do |row|
  #     p row
  #   end
