------------------------------------

             Summary: TableFunction can not work in Flink View
                 Key: FLINK-19735
                 URL: https://issues.apache.org/jira/browse/FLINK-19735
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / API
    Affects Versions: 1.11.1
            Reporter: shizhengchao


TableFunction can't be work in Flink Sql. Here is my code：
{code:sql}
CREATE TABLE test (
  myField   STRING,
  name      STRING
) WITH (
  'connector' = 'kafka-0.11',
  'topic' = 'xxxx',
  'properties.bootstrap.servers' = 'localhost:9092',
  'properties.group.id' = 'mygroup',
  'scan.startup.mode' = 'latest-offset',
  'format' = 'csv'
);
CREATE TABLE print (
  myField   STRING,
  newWord   STRING,
  newLength INT
) WITH (
  'connector' = 'print'
);

CREATE VIEW test_view AS
SELECT myField, newWord, newLength FROM test, LATERAL TABLE(SplitFunction(myField));

INSERT INTO print
SELECT * FROM test_view;
{code}
And the function code as this:
{code:java}
@FunctionHint(output = @DataTypeHint("ROW<newWordSTRING, newLength INT>"))
public class SplitFunction extends TableFunction<Row> {

    public void eval(String str) {
        for (String s : str.split(" ")) {
            collect(Row.of(s, s.length()));
        }
    }
}
{code}
run the sql，cause an error:
