Jark Wu commented on FLINK-4591: -------------------------------- It seems that {{GROUP BY *}} is not allowed in SQL. Maybe we can throw a better exception to explain this when user use star in groupBy. Currently, the exception is "cannot resolve [*] given input [a, b, c]" which is not clear. > Select star does not work with grouping > --------------------------------------- > > Key: FLINK-4591 > URL: https://issues.apache.org/jira/browse/FLINK-4591 > Project: Flink > Issue Type: Improvement > Components: Table API & SQL > Reporter: Timo Walther > > It would be consistent if this would also work: > {{table.groupBy('*).select("*)}} > Currently, the star only works in a plain select without grouping. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
