创建表、分区表、上传下载数据、在表下建立分区、向分区表内上传下载数据等操作:

创建分区表:<数据需要在分到不同的文件后上传到分区表中才有作用,上传到分区时必须选择分区>

odps@ sdrtest>create table t_people_p (id int, name string) partitioned by (gender string); \\创建分区,分区以“性别”为分区标致
odps@ sdrtest>alter table t_people_p add if not exists partition (gender='male'); \\创建分区表,分区表的标致为 性别为 “男性”
odps@ sdrtest>tunnel upload men.txt t_people_p/gender='male'; \\将事先整理好的男性的数据上传到建立好的男性的分区表内
通过odpscmd查看到的写入到分区表的数据:
odps@ sdrtest>read t_people_p;
+------------+------------+------------+
| id | name | gender |
+------------+------------+------------+
| 1 | Michael Jordan | male |
| 3 | Bruce Willis | male |
| 5 | Jhon Knight | male |
| 7 | Chiang Kai-shek | male |
| 9 | David Beckham | male |
+------------+------------+------------+

通过上述方式继续上传女性数据到女性分区表:

odps@ sdrtest>alter table t_people_p add if not exists partition (gender='female');
odps@ sdrtest>tunnel upload women.txt t_people_p/gender='female';
通过odpscmd查看到的写入到分区表的数据:
odps@ sdrtest>read t_people_p;
+------------+------------+------------+
| id | name | gender |
+------------+------------+------------+
| 2 | Angela Dorthea Merkel | female |
