建立分区
create table test_partition_list ( id int, name varchar(64), fdate varchar(10) ) distributed by (id)
partition by list (fdate)
(
partition p1 values ('2017-01-01', '2017-01-02'),
partition p2 values ('2017-01-03'),
default partition pd
);
添加数据
insert into test_partition_list values(1,'aa','2017-01-01');
insert into test_partition_list values(2,'aa','2017-01-01');
insert into test_partition_list values(3,'aa','2017-01-01');
insert into test_partition_list values(4,'aa','2017-01-02');
insert into test_partition_list values(5,'aa','2017-01-02');
insert into test_partition_list values(6,'aa','2017-01-02');
insert into test_partition_list values(7,'aa','2017-01-03');
insert into test_partition_list values(8,'aa','2017-01-03');
insert into test_partition_list values(9,'aa','2017-01-03');
