---------------------------
Summary: When inserting row type fields into sink, the order needs
to be maintained
Key: FLINK-25459
URL: https://issues.apache.org/jira/browse/FLINK-25459
Project: Flink
Issue Type: Improvement
Components: Table SQL / Planner
Affects Versions: 1.14.2
Reporter: qyw
When I insert a row type value into sink, why do I need to maintain the field
order in row?
This is the comparison between my query schema and sink schema:
Query schema: [ceshi: ROW<`name` STRING, `id` INT, `age` INT, `test` ROW<`c`
STRING>>]
Sink schema: [ceshi: ROW<`id` INT, `name` STRING, `age` INT, `test` ROW<`c`
STRING>>]
An error will be thrown:
Exception in thread "main" org.apache.flink.table.api.ValidationException:
Column types of query result and sink for registered table
'default_catalog.default_database.kafka_target' do not match.
Cause: Incompatible types for sink column 'ceshi' at position 0.
