[jira] [Created] (FLINK-10379) Can not use Table Functions in Java Table API


Piotr Nowojski created FLINK-10379:
--------------------------------------

             Summary: Can not use Table Functions in Java Table API
                 Key: FLINK-10379
                 URL: https://issues.apache.org/jira/browse/FLINK-10379
             Project: Flink
          Issue Type: Bug
          Components: Table API & SQL
    Affects Versions: 1.6.1
            Reporter: Piotr Nowojski


As stated in the [documentation|[https://ci.apache.org/projects/flink/flink-docs-stable/dev/table/udfs.html#table-functions],] this is how table functions should be used in Java Table API:
{code:java}
// Register the function.
tableEnv.registerFunction("split", new Split("#"));

myTable.join("split(a) as (word, length)");
{code}
However {{Table.join(String)}} was removed sometime ago and now it is impossible to use Table Functions in Java Table API.
