   CREATE TABLE db.t (
       id int null,
       k largeint null,
       d date null,
       k1 int
   )
   PARTITION BY RANGE (`id`) (
       partition p1 values [(1), (2))
   )
   DISTRIBUTED BY HASH(`k`, `id`) BUCKETS 16
   PROPERTIES (
       "replication_num" = "1"
   );
   
   create materialized view db.mv_t as select d from db.t;
   
   ```
