请教group windows的order by问题

[caigenxing]

需要根据1秒的window中的ROWTIME进行排序，但是报如下错误：
Exception in thread "main" org.apache.flink.table.api.TableException: Sort on a non-time-attribute field is not supported.

我的脚本如下：
CREATE TABLE MyTable(
name varchar,
after varchar,
jstime bigint,
WATERMARK FOR jstime AS withOffset(jstime,1000)
)WITH(
type ='kafka10',
bootstrapServers ='pro1:9092',
kafka.auto.offset.reset ='latest',
topic ='test1',
parallelism ='1',
sourcedatatype ='json'
);
CREATE TABLE result_user_info(
name varchar,
after varchar,
jstime bigint,
ROWTIME datetime
)WITH(
type ='console',
parallelism ='1'
);
insert into result_user_info(name,after,jstime,ROWTIME) (select name ,
after ,
jstime,ROWTIME from MyTable
group by name,after,jstime,TUMBLE(ROWTIME, INTERVAL '1' SECOND),ROWTIME order by ROWTIME)

kafka消息：
{"name":"testname","jstime":3119988231,"after":"{"khh":"我是khh0003"}"}
想请教是否是语法写错了，还是有别的排序方法，多谢

Flink要开启EventTime。你试下
