> You can use the Flink SQL CLI to test the queries:
> 1. Create Source table
> {code:java}
> CREATE TABLE datagenSource (
> order_id BIGINT,
> order_number VARCHAR(20),
> user_id BIGINT,
> shop_id BIGINT,
> product_id BIGINT,
> status BIGINT,
> order_type BIGINT,
> order_created_at TIMESTAMP(3),
> payment_amount_cents BIGINT
> )
> WITH (
> 'connector' = 'datagen',
> 'rows-per-second' = '10'
> ); {code}
> 2. Create the materialized table (without freshness)
> {code:java}
> CREATE MATERIALIZED TABLE users_shops
> PARTITIONED BY (ds)
> WITH(
> 'connector' = 'blackhole'
> )
> REFRESH_MODE = CONTINUOUS
> AS SELECT
> user_id,
> shop_id,
> ds,
> SUM (payment_amount_cents) AS payed_buy_fee_sum,
> SUM (1) AS pv
> FROM (
> SELECT user_id, shop_id, DATE_FORMAT(order_created_at, 'yyyy-MM-dd') AS
> ds, payment_amount_cents FROM datagenSource
> ) AS tmp
> GROUP BY user_id, shop_id, ds; {code}
> 3. run
> {noformat}
> SHOW CREATE MATERIALIZED TABLE users_shops;{noformat}
> And you should see the default FRESHNESS value (3 MINUTE)
> {code:java}
> CREATE MATERIALIZED TABLE `default_catalog`.`default_database`.`users_shops`
> PARTITIONED BY (`ds`)
> WITH (
> 'connector' = 'blackhole'

> FRESHNESS = INTERVAL '3' MINUTE
> REFRESH_MODE = CONTINUOUS
> AS SELECT `tmp`.`user_id`, `tmp`.`shop_id`, `tmp`.`ds`,

> FROM `default_catalog`.`default_database`.`datagenSource` AS `datagenSource`)
> AS `tmp`
> GROUP BY `tmp`.`user_id`, `tmp`.`shop_id`, `tmp`.`ds` {code}
> 4. create materialized table with freshness clause
> {code:java}
> CREATE MATERIALIZED TABLE users_shops_explicit

> 5. run
> {noformat}
> SHOW CREATE MATERIALIZED TABLE users_shops_explicit;{noformat}

> SHOW CREATE MATERIALIZED TABLE users_shops_continuous{code}
