FlinkSql Code

`

public static void main(String[] args) throws Exception {

    final StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
    env.setParallelism(1);

    final StreamTableEnvironment tEnv = StreamTableEnvironment.create(env);

    String sql = "CREATE  TABLE product_order_qrcode_info (\n" +
            "  `id` STRING, " +
            "  `dimension_type` INT ," +
            "  `material_code` STRING ," +
            "  `product_fac` STRING ," +
            "  `create_time` TIMESTAMP," +
            "  PRIMARY KEY (id) NOT ENFORCED\n" +
            ")\n" +
            "WITH (\n" +
            "  'connector' = 'doris',\n" +
            "  'fenodes' = 'xx.xx.xx.xx:xx',\n" +
            "  'table.identifier' = 'xx.xx',\n" +
            "  'username' = 'xxx',\n" +
            "  'password' = 'xx'" +
            ");";

    // register a table in the catalog
    tEnv.executeSql(sql);

    // define a dynamic aggregating query
    final Table result = tEnv.sqlQuery("SELECT * from product_order_qrcode_info where dimension_type=1");

    // print the result to the console
    tEnv.toDataStream(result).print();
    env.execute();
}
