INSERT INTO用于向表中插入数据,遇到主键重复时会自动忽略当前写入数据,不做更新,作用等同于INSERT IGNORE 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','13678973421','杭州',0,'987300','西湖','转塘云栖小镇',23,'2018-03-02 10:00:00');                  
  • 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','13678973421','杭州',0,'987300','西湖','转塘云栖小镇',23,'2018-03-02 10:00:00'),(002368,'张三','13878971234','杭州',0,'987300','西湖','转塘云栖小镇',28,'2018-08-01 11:00:00'),(002369,'王五','13968075284','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','13678973421','杭州',0,'987300','西湖','转塘云栖小镇',23,'2018-03-02 10:00:00'),(002368,'张三','13878971234','杭州',0,'987300','西湖','转塘云栖小镇',28,'2018-08-01 11:00:00'),(002369,'王五','13968075284','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
