Jark Wu updated FLINK-14200:
----------------------------
Fix Version/s: (was: 1.9.1)
1.9.2
> Temporal Table Function Joins do not work on Tables (only TableSources) on
> the query side
> -----------------------------------------------------------------------------------------

> Key: FLINK-14200
> URL: https://issues.apache.org/jira/browse/FLINK-14200
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Planner
> Affects Versions: 1.9.0
> Environment: Java 8, Scala 2.11, Flink 1.9
> Reporter: Benoît Paris
> Priority: Major
> Fix For: 1.9.2

> This only affects the Blink planner. The legacy planner works fine.
> With Orders as a TableSource, and Orders2 as a Table with the same content:
> {code:java}
> tEnv.registerTableSource("Orders", new FooSource(new String[] {"o_currency",
> "o_amount", "o_proctime"}));
> Table orders2 = tEnv.sqlQuery("SELECT * FROM Orders");
> tEnv.registerTable("Orders2", orders2);{code}
> This works (TableSource on the query side):
> {code:java}
> SELECT
> o_amount * r_amount AS amount
> FROM Orders
> , LATERAL TABLE (Rates(o_proctime))
> WHERE r_currency = o_currency{code}
> While this does not (Table on the query side):
> {code:java}
> SELECT
> o_amount * r_amount AS amount
> FROM Orders2
> , LATERAL TABLE (Rates(o_proctime))
> WHERE r_currency = o_currency{code}
> Throwing an NPE in FlinkRelBuilder, called from
> LogicalCorrelateToJoinFromTemporalTableFunctionRule. Attached is Java code
> for reproduction, along with the full log and stacktrace, and a pom.xml.
> EDIT: This may not be Table vs TableSource, maybe more a projection or a
> decorrelate issue? Don't know how the planner works well enough to
> characterize it better.
