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

             Summary: ANSI-style JOIN with Temporal Table Function fails
                 Key: FLINK-14173
                 URL: https://issues.apache.org/jira/browse/FLINK-14173
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Legacy Planner, Table SQL / Planner
    Affects Versions: 1.9.0
         Environment: Java 1.8, Scala 2.11, Flink 1.9 (pom.xml file attached)
            Reporter: Benoît Paris
         Attachments: flink-test-temporal-tables-1.9.zip

The planner fails to generate a plan for ANSI-style joins with Temporal Table Functions. The Blink planners throws with a "Missing conversion is LogicalTableFunctionScan[convention: NONE -> LOGICAL]" message (and some very fancy graphviz stuff). The old planner does a "This exception indicates that the query uses an unsupported SQL feature."

This fails:
{code:java}
 SELECT
   o_amount * r_amount AS amount
 FROM Orders
 JOIN LATERAL TABLE (Rates(o_proctime))
   ON r_currency = o_currency {code}
This works:
{code:java}
 SELECT
   o_amount * r_amount AS amount
 FROM Orders
    , LATERAL TABLE (Rates(o_proctime))
 WHERE r_currency = o_currency{code}
Reproduction with the attached Java and pom.xml files. Also included: stack traces for both Blink and the old planner.

I think this is a regression. I remember using ANSI-style joins with a temporal table function successfully in 1.8.
