-------------------------------------------------------------
Hey Timo([~twalthr] ),
I was checking the unit tests and seems casting from ROW to String is not
supported either implicitly or explicitly:
[https://github.com/apache/flink/blob/master/flink-table/flink-table-common/src/test/java/org/apache/flink/table/types/LogicalTypeCastsTest.java#L159]
Do you mean adding one explicit conversion for this?
Thanks,
Shen
