Registering a Pojo DataSet / DataStream as Table requires alias expressions and does not work with simple field references. However, alias expressions would only be necessary if the fields of the Pojo should be renamed. DataStream persons = // DOES NOT WORK tEnv.registerDataStream ( "Persons", persons, "name, age, address" ); // DOES WORK tEnv.registerDataStream ( "Persons", persons, "name AS name, age AS age, address AS address" ); The following examples show how to use org.apache.flink.table.descriptors.ConnectorDescriptor.These examples are extracted from open source projects.

This means it would be possible to register temporary table with identifier `cat1`.`db1`.`tmpTab`. Even if `tmpTab` exists in the `cat1` catalog in `db1` database.
