Benchao Li closed FLINK-18164.
------------------------------
Resolution: Invalid
> null <> 'str' should be true
> ----------------------------
>
> Key: FLINK-18164
> URL: https://issues.apache.org/jira/browse/FLINK-18164
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / API
> Reporter: Benchao Li
> Priority: Major
>
> Currently, if we compare null with other literals, the result will always be
> false.
> It's because the code gen always gives a default value (false) for the
> result. And I think it's a bug if `null <> 'str'` is false.
> It's reported from user-zh:
> http://apache-flink.147419.n8.nabble.com/flink-sql-null-false-td3640.html
