It's true, the requirements of this issue have evolved quite a bit and we
should adapt the JIRA issue for that ;-)
+1 for creating an issue to support arbitrary inner joins with a single row
input and addressing that issue with this PR.
Once that issue is resolved, we can revisit FLINK-4541 and see what's left
to do.
@AlexanderShoshin, can you open the JIRA issue and adapt this PR to it?

> This should work:

> def main(args: Array[String]): Unit = {
> // set up execution environment
> val env = ExecutionEnvironment.getExecutionEnvironment
> val tEnv = TableEnvironment.getTableEnvironment(env)
> val input = env.fromElements(WC("hello", 1), WC("hello", 1), WC("ciao",
> 1))
> // register the DataSet as table "WordCount"
> tEnv.registerDataSet("WordCount", input, 'word, 'frequency)
> tEnv.registerTable("WordCount2", tEnv.fromDataSet(input, 'word,
> 'frequency).select('word).filter('word !== "hello"))
> // run a SQL query on the Table and retrieve the result as a new Table
> val table = tEnv.sql("SELECT word, SUM(frequency) FROM WordCount WHERE
> word NOT IN (SELECT word FROM WordCount2) GROUP BY word")
> table.toDataSet[WC].print()
> }
