Fabian Hueske created FLINK-4077:
------------------------------------
Summary: Register Pojo DataSet/DataStream as Table requires alias
expression.
Key: FLINK-4077
URL: https://issues.apache.org/jira/browse/FLINK-4077
Project: Flink
Issue Type: Bug
Components: Table API
Affects Versions: 1.1.0
Reporter: Fabian Hueske
Assignee: Fabian Hueske
Fix For: 1.1.0
Registering a Pojo DataSet / DataStream as Table requires alias expressions and
does not work with simple field references. However, alias expressions would
only be necessary if the fields of the Pojo should be renamed.
{code}
DataStream<Person> persons = ...
// DOES NOT WORK
tEnv.registerDataStream(
"Persons",
persons,
"name, age, address");
// DOES WORK
tEnv.registerDataStream(
"Persons",
persons,
"name AS name, age AS age, address AS address");
{code}
We should also allow simple field name references in addition to alias
expressions to rename fields.
