[jira] [Updated] (FLINK-20851) flink datagen produce NULL value

     [ https://issues.apache.org/jira/browse/FLINK-20851?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

appleyuchi updated FLINK-20851:
-------------------------------
    Environment: 



  was:
````
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
https://github.com/knaufk/flink-sql-cookbook/blob/master/recipes/01/01_create_table.md

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.
