回复: json 中 timestamp 类型在json中怎样写才能被 flink sql 识别

Wed, 11 Mar 2020 02:52:57 -0700 

Sorry i sent the Chinese written email to user@ 
Let me translate it to English.

I  create a table using sql-client from kafka topic:
CREATE TABLE order_status (
      out_order_code VARCHAR,
      intput_date TIMESTAMP(3),
      owner_code VARCHAR,
      status INT
  ) WITH (
      'connector.type' = 'kafka',.........
      'format.type' = 'json',      'format.derive-schema' = 'true'   )
Then I send message to the topic: 
{"out_order_code":"MAMICK2020031048","input_date":"2020-03-11T13:00:00.123Z","owner_code":"WDTLEN04","status":90}
But the input_date is not recognized on the sql-client and is null， even i  
tried   1583828700240  "2020-03-11 13:00:00"  "2020-03-11 13:00:00.000" 

How should the timestamp(3) look like in the json message?

Thanks，
Lei

用 sql-client create 了一个 kafka table：
CREATE TABLE order_status (
      out_order_code VARCHAR,
      intput_date TIMESTAMP(3),
      owner_code VARCHAR,
      status INT
  ) WITH (
      'connector.type' = 'kafka',.........
      'format.type' = 'json',      'format.derive-schema' = 'true'   )
然后往 kafka 这个 topic 
发送消息：{"out_order_code":"MAMICK2020031048","input_date":"2020-03-11T13:00:00.123Z","owner_code":"WDTLEN04","status":90}
input_date 在 sql-clinet 端始终是 NULL. 
我把 发送的 input_date 改成 1583828700240  "2020-03-11 13:00:00"  "2020-03-11 
13:00:00.000" 也都不行。 
这个 TIMESTAMP（3）在JSON 中应该写成什么样子呢？

谢谢，
