shizhengchao created FLINK-19735:
------------------------------------
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:
