code: public R raw(String rawExpression, Object... bindValues) {
      peekExprList().raw(rawExpression, bindValues);
      return root;
    }
docs: Add raw expression with an array of parameters.
  <p>
  The raw expression should contain the same number of ? as there are
  parameters.

  <p>
  When properties in the clause are fully qualified as table-column names
  then they are not translated. logical property name names (not fully
  qualified) will still be translated to their physical name.
