-----------------------------------
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*_
