> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Client
> Affects Versions: 1.11.0
> Reporter: Jeff Zhang
> Priority: Major
>
> When I run the following sql example, I get the wrong output
> {code:java}
> SELECT name, COUNT(*) AS cnt FROM (VALUES ('Bob'), ('Alice'), ('Greg'),
> ('Bob')) AS NameTable(name) GROUP BY name; {code}
>
> {code:java}
> Bob 1
> Alice 1
> Greg 1
> Bob 2 {code}
> This is due to we add kind in Row, so the sematics of equals method changes
