---|---  
Affects Versions: |  1.15.0  
Assignee: |  Unassigned  
Components: |  Table SQL / API  
Created: |  28/Jun/22 08:18  
Environment: |

Flink 1.15

Flink ML 2.1  
  
Priority: |  ![Major](cid:jira-generated-image-static-
major-a6cd8ceb-08d3-4cfe-b3e1-fbdc3edab23f) Major  
Reporter: |  [Yunfeng

If the following code is executed with Flink 1.15.0 and Flink ML 2.1



    
    
    import org.apache.flink.ml.linalg.Vectors;
    import org.apache.flink.streaming.api.datastream.DataStream;
    import org.apache.flink.streaming.api.environment.StreamExecutionEnvironment;
    import org.apache.flink.table.api.Table;
    import org.apache.flink.table.api.bridge.java.StreamTableEnvironment;
    import org.apache.flink.types.Row;
    
    public class SqlRawValueExample {
    public static void main(String[] args) {
    StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
    StreamTableEnvironment tEnv = StreamTableEnvironment.create(env);
    
    DataStream<Row> dataStream = env.fromElements(Row.of(Vectors.dense(1.0, 2.0)));
    Table table = tEnv.fromDataStream(dataStream);
    
    table.execute().print();
    }
    }



The following result would be printed out



    
    
    +----+--------------------------------+
    | op |                             f0 |
    +----+--------------------------------+
    | +I |                 SqlRawValue{?} |
    +----+--------------------------------+



while the expected result is

    
    
    +----+--------------------------------+
    | op |                             f0 |
    +----+--------------------------------+
    | +I |                     [1.0, 2.0] |
    +----+--------------------------------+

This behavior affects the readability of the generated results.
