*Hi All,*
*[Explanation]*
Two tables say lineitem and orders:
Table
orderstbl=bsTableEnv.fromDataStream(orders,"a,b,c,d,e,f,g,h,i,orders.rowtime");
Table
lineitemtbl=bsTableEnv.fromDataStream(lineitem,"a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,lineitem.rowtime");
bsTableEnv.registerTable("Orders",orderstbl);
bsTableEnv.registerTable("Lineitem",lineitemtbl)
*#Rgular tumble window works*
Table sqlResult = bsTableEnv.sqlQuery("Select count(Orders.a) FROM Orders
GROUP BY TUMBLE(orders, INTERVAL '5' SECOND)");
Table sqlResult = bsTableEnv.sqlQuery("Select count(Lineitem.a) FROM
Lineitem GROUP BY TUMBLE(lineitem, INTERVAL '5' SECOND)");
*#Datastream TumblingEventTimeWindows joins also works fine*
lineitem.join(orders).where(...).equalTo(...).window(TumblingEventTimeWindows.of(Time.seconds(5))).apply(...)
*But when I try to join them over same window it gives me error, it might
possible I am writing wrong SQL :(*
Table sqlResult = bsTableEnv.sqlQuery("SELECT count(Lineitem.a) FROM "
+ "Orders,Lineitem where Lineitem.a=Orders.a "
+ "GROUP BY TUMBLE(orders, INTERVAL '5' SECOND)");
Exception in thread "main" org.apache.flink.table.api.TableException:
Cannot generate a valid execution plan for the given query:
FlinkLogicalSink(name=[sink], fields=[b])

window=[TumblingGroupWindow], properties=[])
+- FlinkLogicalCalc(select=[orders, a0])

Rowtime attributes must not be in the input rows of a regular join. As a
workaround you can cast the time attributes of input tables to TIMESTAMP
before.
Please check the documentation for the set of currently supported SQL
features.
