[jira] [Commented] (FLINK-10999) Adding time multiple times causes Runtime : java.sql.Timestamp cannot be cast to java.lang.Long

    [ https://issues.apache.org/jira/browse/FLINK-10999?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16697629#comment-16697629 ] 

ideal-hp commented on FLINK-10999:
----------------------------------

To reproduce this problem I have provided the following script:

```

public static DataStream<String> getSource(StreamTableEnvironment tableEnv){
 Table table = tableEnv.sqlQuery("SELECT * FROM (VALUES ('Bob'), ('Lucy')) AS NameTable(name)");
 return tableEnv.toAppendStream(table, String.class);
}

public static void run(StreamTableEnvironment tableEnv)
 throws Exception
{
 DataStream<String> inputStream = getSource(tableEnv);
 //add proctime.proctime
 Table tb1 = tableEnv.fromDataStream(inputStream, "name,proctime.proctime");
 DataStream<Row> stream1 = tableEnv.toAppendStream(tb1, Row.class);
 stream1.getTransformation().setOutputType(tb1.getSchema().toRowType());

 //--Use rowtime.proctime here to simulate rowtime.rowtime
 Table tb2 = tableEnv.fromDataStream(stream1, "name,proctime,rowtime.proctime");
 tableEnv.toAppendStream(tb2, Row.class).print();

 System.out.println("**************************************************");
 System.out.println(tableEnv.execEnv().getExecutionPlan());
 System.out.println("*********************There are no errors here.*****************************");

 //---Running directly below will start to go wrong
 tableEnv.execEnv().execute();
}

```
