Jark Wu commented on FLINK-16938:
---------------------------------
The exception already tell the root cause: query schema and sink schema are not
matched (TIMESTAMP can't be implicitly casted to TIMESTAMP WITH LOCAL TIME
ZONE). I think you may defined a wrong type for ts in sink_table. Could you
share the definition of "sink_table"?
Btw, it seems not the same problem with this JIRA issue?
> SqlTimestamp has lag when convert long to Timestamp
> ---------------------------------------------------
>
> Key: FLINK-16938
> URL: https://issues.apache.org/jira/browse/FLINK-16938
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Planner
> Affects Versions: 1.10.0
> Reporter: YufeiLiu
> Priority: Major
>
> When I set rowtime attribute by using expression 'column.rowtime' , and
> result type is sql.Timestamp, the result will have lag which is equals with
> default timezone offset.
> {code:java}
> tEnv.fromDataStream(stream, "user_action_time.rowtime, user_name, data");
> {code}
> I look into the conversion logic, the field was go through 'long ->
> SqlTimestamp -> Timestamp' conversion.
> {code:java}
> long from = System.currentTimeMillis();
> long to = SqlTimestamp
> .fromEpochMillis(from)
> .toTimestamp()
> .getTime();
> {code}
> The result is {{from!=to}}. In {{SqlTimestamp.toTimestamp()}} using
> {{Timestamp.valueOf(LocalDateTime dateTime)}} which is contain timezone
> infomation, will casue time lag.
> From Timestamp to Timestamp not have this issue, but convert Datastream to
> Table is use StreamRecord.timestamp as rowtime field.
