appleyuchi created FLINK-20851:
----------------------------------

             Summary: flink datagen produce NULL value
                 Key: FLINK-20851
                 URL: https://issues.apache.org/jira/browse/FLINK-20851
             Project: Flink
          Issue Type: Bug
          Components: Client / Job Submission
    Affects Versions: 1.12.0
         Environment: ````
CREATE TABLE orders (
    order_uid  BIGINT,
    product_id BIGINT,
    price      DECIMAL(32, 2),
    order_time TIMESTAMP(3)
) WITH (
    'connector' = 'datagen'
);

SELECT * FROM orders;
````

This DDL will produce NULL for column price.

but it's ok in

①If it's the flink-sql-book's fault,tell me please,
Could you please tell me the right syntax for it?

②If it's the flink's bug,fix it please.

Thanks for your help.
