Hi Flavio,
you're using the TableFunction not correctly. The documentation shows how
to call it in a join() method.
But I agree, the error message should be better.
Best, Fabian

Hi all,
I'm using Flink 1.3.1 and I'm trying to register an UDF but there's
something wrong.
I always get the following exception:
java.lang.UnsupportedOperationException:
org.apache.flink.table.expressions.TableFunctionCall cannot be transformed
to RexNode
at
org.apache.flink.table.expressions.Ex
