Description
after we create materialized view , we can only use desc table_name all to show all the materialized view which have been created.
MySQL [test]> create table sales_records(record_id int, seller_id int, store_id int, sale_date date, sale_amt bigint) distributed by hash(record_id) properties("replication_num" = "1");
Query OK, 0 rows affected (0.00 sec)
MySQL [test]> create materialized view store_amt as select store_id, sum(sale_amt) from sales_records group by store_id;
Query OK, 0 rows affected (0.00 sec)
MySQL [test]> desc sales_records all;

8 rows in set (0.00 sec)
but sometimes we need to know the create materialized view sql like show create table table_name shows.
so the new feature should react like
show create materialized view store_amt;
and the result is the complete sql.
