这是我的连接设置方式:
Connection conn = DriverManager.getConnection(url + dbName + "?useUnicode=true&characterEncoding=utf-8", userName, password);
当tyring为表添加一行时,我收到以下错误:
Incorrect string value: '\xF0\x90\x8D\x83\xF0\x90...' for column 'content' at row 1
我正在插入数千条记录,当文本包含\ xF0时,我总是会收到此错误(即错误的字符串值始终以\ xF0开头).
该列的排序规则为utf8_general_ci.
可能是什么问题呢？
我有一个在生产模式下运行的rails应用程序,但是当用户试图保存记录时,突然出现了这个错误.
Mysql2::Error: Incorrect string value
更多细节(来自生产日志):
Parameters: {"utf8"=>"â<9c><93>" ...
Mysql2::Error: Incorrect string value: '\xC5\x99\xC3\xA1k
Mysql2::Error: Incorrect string value: '\xC5\x99\xC3\xA1k
现在我看到了一些需要删除数据库并重新创建数据库的解决方案,但我不能这样做.
现在mysql显示了这个:
mysql> show variables like 'char%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.04 sec) …如何在java中的unicode Basic Multilingual Plane外部匹配字符(有意删除它们)？
I need to be able to store characters like \xF0\x9F\x94\xA5 in my database, which, according to this post need UTF8mb4 encoding.
So I set up my database with
CREATE DATABASE `myDB` CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci
and verified in the MySQL shell if it was effective:
SHOW FULL COLUMNS FROM myTable;
+---------+------------------+--------------------+----
| Field | Type | Collation | ...
+---------+------------------+--------------------+-----
| id | int(10) unsigned | NULL | ...
| myColumn| text | utf8mb4_general_ci | ...
+---------+------------------+--------------------+-----
So far …
当用户发送包含表情符号的消息时（确切地说，当消息存储在MySql数据库中时），将出现以下错误：
PDOException：SQLSTATE [HY000]：一般错误：1366错误的字符串值：'\ xF0 \ x9F \ x8D \ xB8！...'
我已经检查了以下问题：
前面的所有问题都提出了相同的答案：将表格更改为
utf8mb4排字。这就是我所做的：我将表和相关列更改为utf8mb4_unicode_ci。
但是问题仍然出现。任何的想法 ？
