Loading Data into a Table；MySQL从本地向数据库导入数据

• 在localhost中准备好了一个test数据库和一个pet表：

  1. mysql> SHOW DATABASES;
     +--------------------+
     | Database           |
     +--------------------+
     | information_schema |
     | test               |
     +--------------------+
      rows in set (0.01 sec)
      
     mysql> USE test
     Database changed
     mysql> SHOW TABLES;
     +----------------+
     | Tables_in_test |
     +----------------+
     | pet            |
     +----------------+
      row in set (0.01 sec)

• 在电脑中准备一个pet.txt文件，里面包含想要导入到pet表的数据。（文件中一行代表一条数据，一条数据中的属性用Tab键隔开）
• 向pet表载入pet.txt中的数据：

  1. mysql> LOAD DATA LOCAL INFILE 'E:\Desktop\pet.txt' INTO TABLE pet;
     ERROR  (): The used command is not allowed with this MySQL version

     ERROR原因：服务器端，local_infile默认开启，客户端local_infile默认关闭，因此用的时候需要打开它

  2. mysql> SHOW VARIABLES like 'local_infile';
     +---------------+-------+
     | Variable_name | Value |
     +---------------+-------+
     | local_infile  | OFF   |
     +---------------+-------+
      row  warning (0.04 sec)

     开启local_infile：（开启后，再次执行SHOW VARIABLES like 'local_infile'会看到Value为ON）

  3. mysql> SET GLOBAL local_infile=ON;
     Query OK,  rows affected (0.00 sec)

     重新载入：

  4. mysql> LOAD DATA LOCAL INFILE 'E:\Desktop\pet.txt' INTO TABLE pet;
     ERROR  (HY000):  - No such file or directory)

     ERROR原因：路径应使用'/'   ， 重新载入：

  5. mysql> LOAD DATA LOCAL INFILE 'E:/Desktop/pet.txt' INTO TABLE pet;
     Query OK,  rows affected,  warnings (0.02 sec)
     Records:   Deleted:   Skipped:   Warnings: 　　

     载入完毕，查看载入成功后的pet表： ψ(｀∇´)ψ

  6. mysql> select * from pet;
     +----------+--------+---------+------+------------+------------+
     | name     | owner  | species | sex  | birth      | death      |
     +----------+--------+---------+------+------------+------------+
       |
       |
       |
       |
       |
       |
       |
       |
     +----------+--------+---------+------+------------+------------+
      rows in set (0.00 sec
