If you want something portable just use PreparedStatement.setString()
and parameter placeholders. The "preparation" overhead you are worrying
about is not really an issue as the PreparedStatement implementation is
designed to handle one-shot queries as well as reused queries
efficiently .. since PreparedStatement is often used just for parameter
value interpolation to avoid exactly the issues you are encountering.
