Description

The markdown file location: 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
