数据湖探索 DLI 创建维表

示例

RDS表用于与输入流连接。

   
    
      
      
        CREATE TABLE car_infos (
  car_id STRING,
  car_owner STRING,
  car_brand STRING,
  car_price INT,
  proctime as PROCTIME()
)
  WITH (
  'connector.type' = 'dis',
  'connector.region' = 'cn-north-1',
  'connector.channel' = 'disInput',
  'format.type' = 'csv'
  );

CREATE TABLE  db_info (
  car_id STRING,
  car_owner STRING,
  car_brand STRING,
  car_price INT
)
  WITH (
  'connector.type' = 'gaussdb',
  'connector.driver' = 'org.postgresql.Driver',
  'connector.url' = 'jdbc:gaussdb://xx.xx.xx.xx:8000/xx',
  'connector.table' = 'car_info',
  'connector.username' = 'xx',
  'connector.password' = 'xx',
  'connector.lookup.cache.max-rows' = '10000',
  'connector.lookup.cache.ttl' = '24h'

CREATE TABLE audi_cheaper_than_30w (

)
  WITH (
  'connector.type' = 'dis',
  'connector.region' = 'cn-north-1',
  'connector.channel' = 'disOutput',
  'connector.partition-key' = 'car_id,car_owner',
  'format.type' = 'csv'
  );

INSERT INTO audi_cheaper_than_30w
SELECT a.car_id, b.car_owner, b.car_brand, b.car_price 
FROM car_infos as a join db_info FOR SYSTEM_TIME AS OF a.proctime AS b on a.car_id = b.car_id;
