>
> When accessing nested field in a STRUCTURED SqlType, sometimes
> RelStructuredTypeFlattener will crash with java.lang.IndexOutOfBoundsException
> The test case is in SqlToRelConverterTest.java
> @Test
> public void testNestedColumnCrash() {
> final String sql =
> "select mailing_address.zip from sales.emp_address where home_address.city =
> 'abc'";
> sql(sql).ok();
> }
>
> The root cause is that when generate new RelNode for old RelNode, we did not
> consider whether the flattened field list needs null indicator.
