Unknown system variable 'storage_engine'

從MySQL官網下載測試庫employees_db-full-1.0.6.tar.bz2，導入時出現兩個錯誤

錯誤1：ERROR 1193 (HY000) at line 38: Unknown system variable 'storage_engine'

[root@maomao employees_db]# mysql -t < employees.sql 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
[root@maomao employees_db]# mysql -uroot -p123456 -t < employees.sql

查看本身數據庫存儲引擎

(root@localhost:mysql.sock)[(none)]>show variables like '%engine%';
+----------------------------------+--------+
| Variable_name                    | Value  |
+----------------------------------+--------+

| disabled_storage_engines         |        |
| internal_tmp_disk_storage_engine | InnoDB |
+----------------------------------+--------+
4 rows in set (0.00 sec)

打開腳本編輯，將下面代碼段中標記爲紅色的「storage_engine」修改成「default_storage_engine」

DROP DATABASE IF EXISTS employees;
CREATE DATABASE IF NOT EXISTS employees;
USE employees;

SELECT 'CREATING DATABASE STRUCTURE' as 'INFO';

DROP TABLE IF EXISTS dept_emp,
                     dept_manager,
                     titles,
                     salaries,
                     employees,
                     departments;

   set storage_engine = InnoDB;
-- set storage_engine = MyISAM;
-- set storage_engine = Falcon;
-- set storage_engine = PBXT;
-- set storage_engine = Maria;

select CONCAT('storage engine: ', @@storage_engine) as INFO;

再次導入，成功！

錯誤2：導入成功後進入數據庫查看，發現全部表數據爲空

+---------------------+

| dept_emp            |

| titles              |
+---------------------+
6 rows in set (0.00 sec)

+----------+
| count(*) |
+----------+
|        0 |
+----------+

解決方法：在文件所在目錄下登陸數據庫employees，手動執行腳本employees.sql最後標記爲紅色的語句。

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

具體操做以下

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