MySQL imports SQL scripts on the command line client

1. For example, there is a select_data.sql script file under the f disk.

The contents of the file are as follows:

drop database if exists select_test;
create database select_test;
use select_test;
# 为了保证从表参照的主表存在，通常应该先建主表。
create table teacher_table
(
    # auto_increment:实际上代表所有数据库的自动编号策略，通常用作数据表的逻辑主键。
    teacher_id int auto_increment,
    teacher_name varchar(255),
    primary key(teacher_id)
);
create table student_table
(
    # 为本表建立主键约束
    student_id int auto_increment primary key,
    student_name varchar(255),
    # 指定java_teacher参照到teacher_table的teacher_id列
    java_teacher int,
    foreign key(java_teacher) references teacher_table(teacher_id)
);
insert into teacher_table
values
(null , 'Yeeku');
insert into teacher_table
values
(null , 'Leegang');
insert into teacher_table
values
(null , 'Martine');
insert into student_table
values
(null , '张三' , 1);
insert into student_table
values
(null , '张三' , 1);
insert into student_table
values
(null , '李四' , 1);
insert into student_table
values
(null , '王五' , 2);
insert into student_table
values
(null , '_王五' , 2);

insert into student_table
values
(null , null , 2);
insert into student_table
values
(null , '赵六' , null);

2. Import the sql script in the MySQL command line client

mysql>source f:select_data.sql
