MySQL從本地向數據庫導入數據

• 在localhost中准備好了一個test數據庫和一個pet表：在電腦中准備一個pet.txt文件，里面包含想要導入到pet表的數據。（文件中一行代表一條數據，一條數據中的屬性用Tab鍵隔開）

  1. mysql> SHOW DATABASES; +--------------------+ | Database | +--------------------+ | information_schema | | test | +--------------------+ 2 rows in set (0.01 sec) mysql> USE test Database changed mysql> SHOW TABLES; +----------------+ | Tables_in_test | +----------------+ | pet | +----------------+ 1 row in set (0.01 sec)

• 向pet表載入pet.txt中的數據：

  1. mysql> LOAD DATA LOCAL INFILE 'E:\Desktop\pet.txt' INTO TABLE pet; ERROR 1148 (42000): The used command is not allowed with this MySQL version

     ERROR原因：服務器端，local_infile默認開啟，客戶端local_infile默認關閉，因此用的時候需要打開它

  2. mysql> SHOW VARIABLES like 'local_infile'; +---------------+-------+ | Variable_name | Value | +---------------+-------+ | local_infile | OFF | +---------------+-------+ 1 row in set, 1 warning (0.04 sec)

     開啟local_infile：（開啟后，再次執行SHOW VARIABLES like 'local_infile'會看到Value為ON）

  3. mysql> SET GLOBAL local_infile=ON; Query OK, 0 rows affected (0.00 sec)

     重新載入：

  4. mysql> LOAD DATA LOCAL INFILE 'E:\Desktop\pet.txt' INTO TABLE pet; ERROR 2 (HY000): File 'E:Desktoppet.txt' not found (OS errno 2 - No such file or directory)

     ERROR原因：路徑應使用'/'   ， 重新載入：

  5. mysql> LOAD DATA LOCAL INFILE 'E:/Desktop/pet.txt' INTO TABLE pet; Query OK, 8 rows affected, 7 warnings (0.02 sec) Records: 8 Deleted: 0 Skipped: 0 Warnings: 7　　

     載入完畢，查看載入成功后的pet表： ψ(｀∇´)ψ

  6. mysql> select * from pet; +----------+--------+---------+------+------------+------------+ | name | owner | species | sex | birth | death | +----------+--------+---------+------+------------+------------+ | Fluffy | Harold | cat | f | 1993-02-04 | 0000-00-00 | | Claws | Gwen | cat | m | 1994-03-17 | 0000-00-00 | | Buffy | Harold | dog | f | 1989-05-13 | 0000-00-00 | | Fang | Benny | dog | m | 1990-08-27 | 0000-00-00 | | Bowser | Diane | dog | m | 1979-08-31 | 1995-07-29 | | Chirpy | Gwen | bird | f | 1998-09-11 | 0000-00-00 | | Whistler | Gwen | bird | | 1997-12-09 | 0000-00-00 | | Slim | Benny | snake | m | 1996-04-29 | 0000-00-00 | +----------+--------+---------+------+------------+------------+ 8 rows in set (0.00 sec
