All Implemented Interfaces:

public class SqlCreateTableAs
extends SqlCreateTable

SqlNode to describe the CREATE TABLE AS syntax. The CTAS would create a pipeline to compute the result of the given query and insert data into the derived table.

Example:

 CREATE TABLE base_table (
     id BIGINT,
     name STRING,
     tstmp TIMESTAMP,
     PRIMARY KEY(id)
 ) WITH (
     ‘connector’ = ‘kafka’,
     ‘connector.starting-offset’: ‘12345’,
     ‘format’ =  ‘json’
 )

 CREATE TABLE derived_table
 WITH (
   'connector' = 'jdbc',
   'url' = 'http://localhost:10000',
   'table-name' = 'syncedTable'
 )
 AS SELECT * FROM base_table;
