> in SqlSelect,
> getOperandList() returns with
> {code:java}
> return ImmutableNullableList.of(keywordList, selectList, from, where,
> groupBy, having, windowDecls, orderBy, offset, fetch, hints);
> {code}
> while we trying to setOperand() by the returned list, we have AssertionError.
> seems the setOperand only set the first ten operands.
> {code:java}
> @Override public void setOperand(int i, @Nullable SqlNode operand) {
> switch (i) {
> case 0:
> keywordList = requireNonNull((SqlNodeList) operand);
> break;
> case 1:
> selectList = requireNonNull((SqlNodeList) operand);
> break;
> case 2:
> from = operand;
> break;
> case 3:
> where = operand;
> break;
> case 4:
> groupBy = (SqlNodeList) operand;
> break;
> case 5:
> having = operand;
> break;
> case 6:
> windowDecls = requireNonNull((SqlNodeList) operand);

> a minor modification could be:
> {code:java}
> @Override public void setOperand(int i, @Nullable SqlNode operand) {
> switch (i) {
> case 0:
> keywordList = requireNonNull((SqlNodeList) operand);
> break;
> case 1:

> groupBy = (SqlNodeList) operand;
> break;
> case 5:
> having = operand;

> case 6:

> case 7:
> orderBy = (SqlNodeList) operand;
