INSERT INTO statement - Development References| Alibaba Cloud Documentation Center

This topic describes how to write data to one or more sinks in a job.

Example of how to write data to a sink

Statement for creating a source table

CREATE TABLE datagen_source (
  name VARCHAR,
  score BIGINT
) WITH (
  'connector' = 'datagen' 
);

Statement for creating a result table

create table blackhole_sink(
  name VARCHAR,
  score BIGINT
) WITH (
  'connector' = 'blackhole' 
);

DML statement for writing data from the source table to the result table

INSERT INTO blackhole_sink SELECT UPPER(name), score FROM datagen_source;

Example of how to write data to multiple sinks

Statement for creating a source table

CREATE TABLE datagen_source (
  name VARCHAR,
  score BIGINT
) WITH (
  'connector' = 'datagen'  
);

Statement for creating a result table A

CREATE TABLE blackhole_sinkA(
  name VARCHAR,
  score BIGINT
) WITH (
  'connector' = 'blackhole' 
);

Statement for creating a result table B

CREATE TABLE blackhole_sinkB(
  name VARCHAR,
  score BIGINT
) WITH (
  'connector' = 'blackhole' 
);

DML statement for writing data from the source table to multiple result tables

In this example, data is written to two sinks.

BEGIN STATEMENT SET;      -- This is required when you write data to multiple sinks. 
INSERT INTO blackhole_sinkA 
  SELECT UPPER(name), sum(score) 
  FROM datagen_source 
  GROUP BY UPPER(name);
INSERT INTO blackhole_sinkB 
  SELECT LOWER(name), max(score) 
  FROM datagen_source 
  GROUP BY LOWER(name);
END;      -- This is required when you write data to multiple sinks.

Note The statement that writes data to multiple sinks must start with BEGIN STATEMENT SET; and end with END;.
