----------------------------------
Summary: Cannot alias Tuple and Row fields when converting
DataStream to Table
Key: FLINK-17420
URL: https://issues.apache.org/jira/browse/FLINK-17420
Project: Flink
Issue Type: Bug
Components: Table SQL / API
Affects Versions: 1.10.0
Reporter: Gyula Fora
It is impossible to alias Tuple and Row fields when converting DataStream to
Table.
{code:java}
tableEnv.fromDataStream(env.fromElements(Tuple2.of("a", 1)), "f0 as name, f1 as
age");
{code}
This leads to the following error:
Alias 'name' is not allowed if other fields are referenced by position
org.apache.flink.table.typeutils.FieldInfoUtils#isReferenceByPosition method
