[ https://issues.apache.org/jira/browse/CALCITE-2963?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Will Yu updated CALCITE-2963:
-----------------------------
Priority: Minor (was: Major)
> IndexOutOfBoundsException in RelStructuredTypeFlattener when accessing nested fields
> ------------------------------------------------------------------------------------
>
> Key: CALCITE-2963
> URL: https://issues.apache.org/jira/browse/CALCITE-2963
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.19.0
> Reporter: Will Yu
> Priority: Minor
>
> 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.
