7.3 Write data

• create database

create database school;

• View new database

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| data               |
| information_schema |
| mysql              |
| performance_schema |
| school             |
| sys                |
+--------------------+
6 rows in set (0.00 sec)

• Enter the school database

mysql> use school;
Database changed

• Create a new data table and create an empty data table.

 CREATE TABLE IF NOT EXISTS `student`(
     `id` INT UNSIGNED AUTO_INCREMENT,
      `name` VARCHAR(100) NOT NULL,
    `gender` TINYINT NOT NULL,
     `age` INT UNSIGNED,
    `class` INT UNSIGNED,
      `score` INT UNSIGNED,
      PRIMARY KEY ( `id` )
    )ENGINE=InnoDB DEFAULT CHARSET=utf8;

• Write data to the data table student.

 insert into student ( name, gender, age, class,  score ) values ( "李一成", "1", "16", "1", "78" );
 insert into student ( name, gender, age, class,  score ) values ( "王萌", "0", "15", "2", "88" );
 insert into student ( name, gender, age, class,  score ) values ( "张磊", "1", "16", "4", "98" );

• Query data table content

mysql> select * from student;
+----+-----------+--------+------+-------+-------+
| id | name      | gender | age  | class | score |
+----+-----------+--------+------+-------+-------+
|  1 | 李一成    |      1 |   16 |     1 |    78 |
