[jira] [Updated] (FLINK-10408) Cannot use window information in
Table functions
[ https://issues.apache.org/jira/browse/FLINK-10408?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alexis Sarda-Espinosa updated FLINK-10408:
------------------------------------------
Description:
Given the examples shown in [here|[https://flink.apache.org/news/2017/03/29/table-sql-api-update.html],] I assume the following should work:
{code:java}
ExecutionEnvironment execEnv = ExecutionEnvironment.getExecutionEnvironment();
BatchTableEnvironment tableEnv = TableEnvironment.getTableEnvironment(execEnv);
DataSource<Tuple3<Timestamp, String, Double>> source = execEnv.fromElements(
new Tuple3<>(Timestamp.valueOf("2018-09-20 22:00:00"), "a", 1.3),
new Tuple3<>(Timestamp.valueOf("2018-09-20 22:01:00"), "a", 2.1),
new Tuple3<>(Timestamp.valueOf("2018-09-20 22:02:00"), "a", 3.0),
new Tuple3<>(Timestamp.valueOf("2018-09-20 22:00:00"), "b", 2.2),
new Tuple3<>(Timestamp.valueOf("2018-09-20 22:01:00"), "b", 1.8)
);
Table table = tableEnv.fromDataSet(source)
.window(Slide.over("2.minutes").every("1.minute").on("f0").as("w"))
.groupBy("f1, w")
.select("(f2 * (f0 - w.start).exp() / 1.hour).sum" +
" / ((f0 - w.start).exp() / 1.hour).sum");
tableEnv.toDataSet(table, Row.class).print();
{code}
However, I get the following exception:
{code:java}
org.apache.flink.table.api.ValidationException: Cannot resolve [w] given input [f0, f1, f2]
{code}
Maybe related to this issue?
