Hi Biao, I figured that the error happens only when there is a JOIN in the select. But I will put together a simple example.

Hi Ed, Would you mind giving a minimal example to reproduce your case? I tried a pretty simple case like this in a mini cluster: ``` tEnv.createTemporaryView("test", env.fromData(1, 2, 3)); Table table = tEnv.sqlQuery("SELECT * FROM test"); table.execute().collect().next(); ``` But I failed to reproduce the exception you attached :( Best, Biao Geng Eduard Skhisov via user <user@flink.apache.org<mailto:user@flink.apache.org>> 于2024年5月1日周三
