------------------------------------

             Summary: Table with time attribute cannot be written to CsvTableSink
                 Key: FLINK-8012
                 URL: https://issues.apache.org/jira/browse/FLINK-8012
             Project: Flink
          Issue Type: Bug
          Components: Table API & SQL
    Affects Versions: 1.3.2, 1.4.0
            Reporter: Fabian Hueske
            Assignee: Fabian Hueske
            Priority: Critical
             Fix For: 1.4.0, 1.3.3


A Table with a time attribute ({{TimeIndicatorTypeInfo}}) cannot be written to a {{CsvTableSink}}.
Trying to do so results in the following exception:

{code}
Exception in thread "main" org.apache.flink.table.api.TableException: The time indicator type
is an internal type only.

{code}

The time attribute should be automatically converted into a {{SQL_TIMESTAMP}} type.
