-----------------------------------

             Summary: Correct the error in the code example in page 'aggregate-functions'.
                 Key: FLINK-21042
                 URL: https://issues.apache.org/jira/browse/FLINK-21042
             Project: Flink
          Issue Type: Improvement
          Components: Documentation
    Affects Versions: 1.12.1, 1.13.0
            Reporter: Roc Marshal


The markdown file location: flink/docs/dev/table/functions/udfs.zh.md & flink/docs/dev/table/functions/udfs.md 

The target url : [https://ci.apache.org/projects/flink/flink-docs-master/dev/table/functions/udfs.html#aggregate-functions]

 

The original content:

*SELECT myField, WeightedAvg(value, weight) FROM MyTable GROUP BY myField*

 

The 'value' is a reserved keyword of the flink table module,So the correct usage should to execute in back quotes .

_*SELECT myField, WeightedAvg(`value`, weight) FROM MyTable GROUP BY myField*_
