> incorrect implicit type conversion between numeric and (var)char
> ----------------------------------------------------------------
>
> Key: FLINK-24492
> URL: https://issues.apache.org/jira/browse/FLINK-24492
> Project: Flink
> Issue Type: Bug
> Reporter: xuyangzhong
> Priority: Minor
>
> The result of the sql "select 1 = '1'" is false. This is caused by the
> CodeGen. CodeGen incorrectly transform this "=" to "BinaryStringData.equals
> (int 1)". And "<>" has the same wrong result.
> In my opinion, "=" should have the same behavior with ">" and "<", which have
> the correct results. So before calcite solves this bug, we'd better
> temporarily forbidding this implicit type conversion in "=" and "<>".
