mysql导入文件中文乱码的解决办法:首先创建数据库并制定编码;然后在导入数据库文件之前,制定编码set names utf8即可。
改完后也不看了,直接插数据试试:
insert into book
(id,bookname,size,price)
values
(1,"测试",2,3)
;
插入成功,查看数据是不是还中文乱码,发现并不乱码了:
那么开始进行下一步,导出sql文件,进入到mysql的bin目录下,开始通过命令导出,这个过程需要输入密码
E:\mysql-5.7.28-winx64\bin>mysqldump -u root -p test > test.sql
Enter password: *******
导出的文件,表的编码格式utf8,与之前导入文件的比较并看不出什么问题。
那么,就是之前导入文件的过程,创建数据库的过程除了问题,查看之前导入的mydb.sql 的mydb数据库结构,果然不对:
mysql> use mydb;
Database changed
mysql> show variables like 'character_set_database';
+------------------------+--------+
| Variable_name | Value |
+------------------------+--------+
| character_set_database | latin1 |
+------------------------+--------+
1 row in set, 1 warning (0.00 sec)
遂修改之:alert database mydb character set utf8;
然后再查看表的编码,发现有鬼:
mysql> show create table sp_user_cart;
+--------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Table | Create Table |
+--------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| sp_user_cart | CREATE TABLE `sp_user_cart` (
`cart_id` int(11) unsigned NOT NULL AUTO_INCREMENT COMMENT '涓婚敭',
`user_id` int(11) unsigned NOT NULL COMMENT '瀛﹀憳id',
`cart_info` text CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci COMMENT '璐?墿杞﹁?鎯呬俊鎭?紝浜岀淮鏁扮粍搴忓垪鍖栦俊鎭',
`created_at` timestamp NULL DEFAULT NULL,
`updated_at` timestamp NULL DEFAULT NULL,
`delete_time` timestamp NULL DEFAULT NULL,
PRIMARY KEY (`cart_id`)
) ENGINE=InnoDB AUTO_INCREMENT=22 DEFAULT CHARSET=utf8
utf8mb4_unicode_ci 这个东西是怎么出来的...
然后改了编码,查询,还是不对,想起来之前创建数据库,可能是忘记设置编码,导入的东西本来就乱码了,也或者是my.ini配置不对,从头开始用正确流程试试吧。
先查看数据库的编码设置:show variables like 'character%';
发现很混乱:
mysql> show variables like 'character%';
+--------------------------+----------------------------------------+
| Variable_name | Value |
+--------------------------+----------------------------------------+
| character_set_client | gbk |
| character_set_connection | gbk |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | gbk |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | D:\mysql-5.7.29-winx64\share\charsets\ |
+--------------------------+----------------------------------------+
开始改,通过一系列的set
set character_set_client = utf8;
得到结果
+--------------------------+----------------------------------------+
| Variable_name | Value |
+--------------------------+----------------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | utf8 |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | D:\mysql-5.7.29-winx64\share\charsets\ |
+--------------------------+----------------------------------------+
创建数据库并制定编码:CREATE DATABASE test2 CHARACTER SET utf8 COLLATE utf8_general_ci;
使用:use test2
在导入数据库文件之前,制定编码set names utf8;
导入:source F:xxxx\xxxx\mydb.sql;
不算漫长的等待之后,查询,不乱码了
mysql> select * from sp_role;
+---------+---------------+---------------------------------------------------------------------------------------------
