/** is used for parameter setting, commonly implemented in conjunction with
    PreparedStatements.


    <p>
    <b>Note:</b> The setXXX methods for setting IN parameter values
    must specify types that are compatible with the defined SQL type of
    the input parameter. For instance, if the IN parameter has SQL type
    Integer, then the method
    com::sun::star::sdbc::XParameters::setInt()
    should be used.

    </p>
    <p>
    If arbitrary parameter type conversions are required, the method
    com::sun::star::sdbc::XParameters::setObject()
    should be used with a target SQL type.

    <code>con</code>
    is an active connection.
