void main() {
  connect(
    "scott",
    "tiger",
    "(DESCRIPTION="
      "(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))"
      "(CONNECT_DATA=(SERVICE_NAME=XE)(SERVER=DEDICATED)))")
      .then((connection) {
          connection.select("insert into emp(name, age) values('defgh', 2345)");
          resultset = connection.select("select name, age from emp");
          while (resultset.next()) {
            print("${resultset.getString(1)}: ${resultset.getInt(2)}");
          }
  });
}
