-----------------------------
Summary: org.apache.flink.table.codegen.CodeGenException:
Unsupported call: TUMBLE
Key: FLINK-9021
URL: https://issues.apache.org/jira/browse/FLINK-9021
Project: Flink
Issue Type: Bug
Components: Table API & SQL
Affects Versions: 1.4.2
Environment: java 8
flink 1.4.2
scala 2.11
Reporter: yizhou
I have a stream like this: {{<_time(timestamp), uri(string), userId(int)>}}.
The {{_time}} attribute is rowtime and I register it as a table:
{{tableEnv.registerDataStream("userVisitPage", stream, "_time.rowtime,
uri,userId");}}
{{Then I query the table:}}
{code:java}
final String sql = "SELECT tumble_start(_time, interval '10' second) as
timestart, "
+ " count(distinct userId) as uv, "
+ " uri as uri, "
+ " count(1) as pv "
+ "FROM userVisitPage "
+ "GROUP BY tumble(_time, interval '10' second), uri";
final Table table = tableEnv.sqlQuery(sql);
tableEnv.toRetractStream(table, Row.class);
{code}
{{but occur exceptions:}}{{}}
