一、建立分割槽表user

CREATE TABLE user 
( user_id BIGINT, gender BIGINT COMMENT '0 unknow,1 male, 2 Female', age BIGINT) 
PARTITIONED BY (region string, dt string);

二、新增分割槽

ALTER TABLE user ADD IF NOT EXISTS PARTITION(region='guangzhou',dt='20180725');

三、往分割槽插入資料

  方式一：直接插入

INSERT INTO user PARTITION(region='guangzhou',dt='20180725') VALUES(1,1,24);
 

  方式二：利用select 子句插入    

CREATE TABLE user_input(user_id BIGINT, gender BIGINT, age BIGINT);
INSERT INTO user_input VALUES(2,1,26);
INSERT INTO user_input VALUES(3,2,26);
INSERT INTO user PARTITION(region='guangzhou',dt='20180725') SELECT user_id,gender,age FROM user_input;

  方式三：利用 tunnel 工具上傳資料檔案

四、查詢分割槽資料

SELECT * FROM user WHERE region='guangzhou'and dt='20180725';
