Gyula Fora reassigned FLINK-38913:
----------------------------------
Assignee: david radley
> ArrayIndexOutOfBoundsException when creating a table with computed rows
> including casts to null
> -----------------------------------------------------------------------------------------------
>
> Key: FLINK-38913
> URL: https://issues.apache.org/jira/browse/FLINK-38913
> Project: Flink
> Issue Type: Technical Debt
> Components: Table SQL / Planner
> Affects Versions: 2.2.0
> Reporter: david radley
> Assignee: david radley
> Priority: Major
>
> If you try to create a table in the SQL client with SQL like this :
> _CREATE TABLE orders (_
> _`const_requestBody_arrayOfObjectsOfObjects` AS ARRAY[ROW(ROW('I''m
> happy', CAST(NULL AS BOOLEAN))), ROW(CAST(NULL AS ROW<`string` STRING,
> `boolean` BOOLEAN>))]_
> _) WITH (_
> _'connector' = 'filesystem',_
> _'path' =
> 'file:///Users/davidradley/bashscripts/sqlscripts/json/test_avro.json',_
> _'format' = 'avro'_
> _);_
>
> _We get an ArrayIndexOutOfBoundsException_ exception thrown. The problem is
> [here]([https://github.com/apache/flink/blob/0261d498cb4538aefc4bb2f14ef08d0dec6db812/flink-table/flink-sql-parser/src/main/java/org/apache/flink/sql/parser/type/ExtendedSqlRowTypeNameSpec.java#L124)]
> where we address an element in the comments array, but the element does not
> exist. The proposed fix is to change this code to:
> _if (i < comments.size() && comments.get != null) {_
>
> There is one other place in the code base that has this if that I will also
> change.
>
> This does not occur at Flink 1.20.
