             Summary: Outdated SQL Temporal Join Example
                 Key: FLINK-24115
                 URL: https://issues.apache.org/jira/browse/FLINK-24115
             Project: Flink
          Issue Type: Bug
          Components: Documentation, Table SQL / API
            Reporter: Nico Kruber


[https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/dev/table/sql/queries/joins/#event-time-temporal-join]
 is missing a primary key in the Table DDL.

Also, the following note does not map the current example anymore:
{quote}
Note: The event-time temporal join requires the primary key contained in the 
equivalence condition of the temporal join condition, e.g., The primary key 
P.product_id of table product_changelog to be constrained in the condition 
O.product_id = P.product_id.
