GitHub user twalthr opened a pull request: https://github.com/apache/flink/pull/1679 [FLINK-3226] Translation of scalar function substring() This PR implements the scalar function `substring()` for the Table API on Calcite. Additionally, it already contains preparations for more built-in SQL functions. I implemented test utils for scalar functions `ScalarFunctionsTest` and added a similar concept to Calcites `CallImplementor` named `CallGenerator`. For now, I kept the `Substring` expression node, but I would like to remove it and use a generic `Call` expression. I think we don't need a case class for every operator. What do you think?
