Java Table API
[ https://issues.apache.org/jira/browse/FLINK-10379?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16622933#comment-16622933 ]

> 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
> Assignee: Hequn Cheng
> Priority: Critical
>
> 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.
