ERROR at line 108: Failed to open file 'load_departments.dump', error: 2
修改employees.sql文件
- 将
set storage_engine = InnoDB;改为set default_storage_engine = InnoDB; - 将
select CONCAT('storage engine: ', @@storage_engine) as INFO;改为select CONCAT('storage engine: ', @@default_storage_engine) as INFO; - 所有*.dump文件为绝对路径，比如
source D:/practice/sql/mysql/employee_sample/employees_db/load_departments.dump;改为source D:/practice/sql/mysql/employee_sample/employees_db/load_departments.dump;
然后重新运行成功了，如下
D:\mysql\bin>mysql -t -u root -p < D:\practice\sql\mysql\employee_sample\employees_db\employees.sql

- md5和sha方式验证下载的数据库完整性出错，错误如下
D:\mysql\bin>mysql -t -u root -p < D:\practice\sql\mysql\employee_sample\employees_db\test_employees_sha.sql

ERROR 1193 (HY000) at line 28: Unknown system variable 'storage_engine'
解决方法，将test_employees_sha.sql和test_employees_md5.sql文件中 SET storage_engine=MyISAM; 改为 set default_storage_engine = InnoDB;
修改完后，再次运行显示成功，如下：
D:\mysql\bin>mysql -t -u root -p < D:\practice\sql\mysql\employee_sample\employees_db\test_employees_sha.sql
