Solution: log in to the database employees in the directory where the file is located, manually execute the script employees.sql, and finally mark the statement in red

[root@maomao employees_db]# ls
Changelog                   employees.sql           load_employees.dump  README
employees_partitioned2.sql  load_departments.dump   load_salaries.dump   test_employees_md5.sql
employees_partitioned3.sql  load_dept_emp.dump      load_titles.dump     test_employees_sha.sql
employees_partitioned.sql   load_dept_manager.dump  objects.sql

cat employees.sql
CREATE TABLE salaries (
  emp_no   INT       NOT NULL,
  salary   INT       NOT NULL,
  from_date  DATE      NOT NULL,
  to_date   DATE      NOT NULL,
  KEY     (emp_no),
  FOREIGN KEY (emp_no) REFERENCES employees (emp_no) ON DELETE CASCADE,
  PRIMARY KEY (emp_no, from_date)
);

SELECT 'LOADING departments' as 'INFO';
source load_departments.dump ;
SELECT 'LOADING employees' as 'INFO';
source load_employees.dump ;
SELECT 'LOADING dept_emp' as 'INFO';
source load_dept_emp.dump ;
SELECT 'LOADING dept_manager' as 'INFO';
source load_dept_manager.dump ;
SELECT 'LOADING titles' as 'INFO';

SELECT 'LOADING salaries' as 'INFO';
source load_salaries.dump ;

The specific operation is as follows

[root@maomao employees_db]# mysql -uroot -p123456
