wenhuitang edited a comment on issue #8417: [hotfix][javadocs] Correct the example of select for Interface Table. URL: https://github.com/apache/flink/pull/8417#issuecomment-491762504 > Hi @wenhuitang. To be honest I don't think this change improves the javadoc. The result of the original example depends on how the orignal `tab` Table was defined. So it would work if e.g. the schema of tab was `(key: String, ` The average`: Integer)`. Your example has the same problem/shortcoming that it does not have the context. So your examples also can fail if a wrong Table is used. > > To sum up I'm -1 for this change. Hi @dawidwys ， thanks for your review. I thought this example was wrong because this example select a field 'key with a aggregation without using groupBy. It seems that the example " tab.select('key, 'value.avg + " The average" as 'average)" still causes ValidationException even the schema of tab was (key: String, value: Integer, The average: Integer). and the example is kind of misleading, maybe we can found a better example.
