connection      = connection_pool.get_connection

rows_changed = connection.execute(<<-EOSQL)
  CREATE TABLE cars (id INTEGER PRIMARY KEY, model TEXT, brand_id INTEGER, manufactured_at DATETIME);
  CREATE TABLE brands (id INTEGER PRIMARY KEY, name TEXT);
  INSERT INTO brands (name) VALUES ("Ford");
  INSERT INTO brands (name) VALUES ("VW");
  INSERT INTO cars (model, brand_id) VALUES ("Focus", (SELECT id FROM brands WHERE name = "Ford"));
  INSERT INTO cars (model, brand_id) VALUES ("Golf", (SELECT id FROM brands WHERE name = "VW"));
  UPDATE cars SET manufactured_at = CURRENT_TIMESTAMP;
EOSQL

puts rows_changed #=> 2
