 * @param precision the precision of the column to convert this value to.
 *        The special constant <code>-1</code> is used to indicate that
 *        the precision plays no role when converting the value
 * @param mode the conversion mode
 * @param column the column (if any), used for to improve the error message if conversion fails
 * @param enumerators the ENUM datatype enumerators (if any),
