云原生数据仓库AnalyticDB：INSERT INTO

语法

INSERT [IGNORE] 
    INTO table_name 
    [( column_name [, …] )]
    [VALUES]
    [(value_list[, …])]
    [query];     

参数

• IGNORE：可选参数，若系统中已有相同主键的记录，新记录不会被写入。

• column_name：可选参数，列名。

• query：通过定义查询，将一行或多行数据插入表中。

注意事项

如果插入数据时不指定列名，则要插入的数据必须和CREATE TABLE语句中声明的列的顺序一致。

示例

创建CUSTOMER和COURSES表。

CREATE TABLE customer (
  customer_id bigint NOT NULL COMMENT '顾客ID',
  customer_name varchar NOT NULL COMMENT '顾客姓名',
  phone_num bigint NOT NULL COMMENT '电话',
  city_name varchar NOT NULL COMMENT '所属城市',
  sex int NOT NULL COMMENT '性别',
  id_number varchar NOT NULL COMMENT '身份证号码',
  home_address varchar NOT NULL COMMENT '家庭住址',
  office_address varchar NOT NULL COMMENT '办公地址',
  age int NOT NULL COMMENT '年龄',
  login_time timestamp NOT NULL COMMENT '登录时间',
  PRIMARY KEY (login_time，customer_id，phone_num)
)
DISTRIBUTED BY HASH(customer_id)
PARTITION BY VALUE(DATE_FORMAT(login_time, '%Y%m%d')) LIFECYCLE 30
COMMENT '客户信息表';           

CREATE TABLE courses(
id bigint AUTO_INCREMENT PRIMARY KEY,
name varchar(20) NOT NULL,
grade varchar(20) default '三年级',
submission_date timestamp
)
DISTRIBUTED BY HASH(id)          

• 向CUSTOMER表中插入一条数据。

  INSERT INTO customer(customer_id,customer_name,phone_num,city_name,sex,id_number,home_address,office_address,age,login_time) 
  values
  (002367,'杨过','13900001234','杭州',0,'987300','西湖','转塘云栖小镇',23,'2018-03-02 10:00:00');                  

• 使用INSERT INTO ... ON DUPLICATE KEY UPDATE...向CUSTOMER表中插入一条数据。

  INSERT INTO customer 
  values
  (002367,'杨过','13900001234','杭州',0,'987300','西湖','转塘云栖小镇',23,'2018-03-02 10:00:00'); 
  ON DUPLICATE KEY
  UPDATE age=23;

• 向CUSTOMER表中插入多条数据。

  INSERT INTO  customer(customer_id,customer_name,phone_num,city_name,sex,id_number,home_address,office_address,age,login_time) 
  values
  (002367,'李四','13900001234','杭州',0,'987300','西湖','转塘云栖小镇',23,'2018-03-02 10:00:00'),(002368,'张三','13900001111','杭州',0,'987300','西湖','转塘云栖小镇',28,'2018-08-01 11:00:00'),(002369,'王五','13900002222','杭州',1,'987300','西湖','转塘云栖小镇',35,'2018-09-12 08:11:00');                 

• 向CUSTOMER表中插入多条数据时，可以省略列名。

  INSERT INTO 
  customer values
  (002367,'李四','13900001234','杭州',0,'987300','西湖','转塘云栖小镇',23,'2018-03-02 10:00:00'),(002368,'张三','13900001111','杭州',0,'987300','西湖','转塘云栖小镇',28,'2018-08-01 11:00:00'),(002369,'王五','13900002222','杭州',1,'987300','西湖','转塘云栖小镇',35,'2018-09-12 08:11:00');                

• 向COURSES表中插入一条数据。

  INSERT INTO courses (name,submission_date) values("Jams",NOW());                

• INSERT query示例请参见INSERT SELECT FROM。
