MySQL命令視窗中文亂碼或插入中文資料失敗
阿新 • • 發佈：2018-11-05
在Windwos上使用命令視窗操作MySQL資料庫時，如果命令視窗的字元編碼與資料庫不一致時，就會出現中文亂碼的情況
比如查詢會出現中文亂碼，或者插入資料會出現錯誤“ERROR 1366 (HY000): Incorrect string value: '\xD5\xC5\xC8\xFD' for column 'name' at row 1”
mysql> insert into user(name,gender,age) values('張三','男',22);
ERROR 1366 (HY000): Incorrect string value: '\xD5\xC5\xC8\xFD' for column 'name' at row 1
mysql> select * from user;
+----+----------+--------+-----+---------------------+| id | name | gender | age | updated_time |
+----+----------+--------+-----+---------------------+| 1 | zhangsan | M | 22 | 2018-10-31 17:03:25 |
| 2 | 寮犱笁 | 鐢? | 22 | 2018-11-01 09:01:43 |
+----+----------+--------+-----+---------------------+2 rows in set (0.00 sec)這時可以先檢視下環境編碼配置，我的是utf8，結果是下面這樣
mysql> show variables like 'char%'; +--------------------------+---------------------------------------------------------+| Variable_name | Value | +--------------------------+---------------------------------------------------------+| character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | C:\Program Files\MySQL\MySQL Server 5.5\share\charsets\ | +--------------------------+---------------------------------------------------------+8 rows in set (0.00 sec)
檢視windwos命令視窗的的屬性可知，編碼格式為GBK且不能更改
這時我們可以使用“set names gbk;”來指定客戶端傳送給mysql語句時的編碼格式，並且可以看到client、connection、results三個變數的編碼格式變為了gbk，其它的沒有變化
mysql> set names gbk; Query OK, 0 rows affected (0.00 sec) mysql> show variables like 'char%'; +--------------------------+---------------------------------------------------------+| Variable_name | Value | +--------------------------+---------------------------------------------------------+| character_set_client | gbk | | character_set_connection | gbk | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | gbk | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | C:\Program Files\MySQL\MySQL Server 5.5\share\charsets\ | +--------------------------+---------------------------------------------------------+8 rows in set (0.00 sec)
再次執行下插入操作沒問題了，查詢資料中文也不會亂碼了
mysql> insert into user(name,gender,age) values('張三','男',22);
Query OK, 1 row affected (0.04 sec)
mysql> select * from user;
