## Proposed changes
Support to create partition materialized view using nodata table
Such as the table def as following:
> CREATE TABLE `test_no_data` (
> `user_id` LARGEINT NOT NULL COMMENT '"用户id"',
> `date` DATE NOT NULL COMMENT '"数据灌入日期时间"',
> `num` SMALLINT NOT NULL COMMENT '"数量"'
> ) ENGINE=OLAP
> DUPLICATE KEY(`user_id`, `date`, `num`)
> COMMENT 'OLAP'
> PARTITION BY RANGE(`date`)
> (PARTITION p201701_1000 VALUES [('0000-01-01'), ('2017-02-01')),
> PARTITION p201702_2000 VALUES [('2017-02-01'), ('2017-03-01')),
> PARTITION p201703_all VALUES [('2017-03-01'), ('2017-04-01')))
> DISTRIBUTED BY HASH(`user_id`) BUCKETS 2
> PROPERTIES ('replication_num' = '1') ;
when table test_no_data has no data, it also support to create partition
materialized view as following:
> CREATE MATERIALIZED VIEW no_data_partition_mv
> BUILD IMMEDIATE REFRESH AUTO ON MANUAL
> partition by(`date`)
> DISTRIBUTED BY RANDOM BUCKETS 2
> PROPERTIES ('replication_num' = '1')
> AS
> SELECT * FROM test_no_data where date > '2017-05-01';
