ERROR 1366(HY000):字符串值不正确:'\ xF0\x9F\x98\x9C'表示第1行的"注释"列

Question

这是我的sql:

INSERT INTO comments (createdate,userid,profileid,comment,status) 
VALUES (1449503167,65704,65704,'@Mr_S66 Wish I was There For The Xmas Party I Miss My Studio 66 Family 😜',15)

这是我的评论架构:

继承我的输出sql query:

ERROR 1366(HY000):字符串值不正确:'\ xF0\x9F\x98\x9C'表示第1行的"注释"列

还不太清楚如何解决这个问题.可能会过滤注释文本using php以适应字符串值.

Answer 1

您的环境中的某些内容未设置为正确处理Unicode文本.

F0 9F 98 9C在您的查询中错误地表示为"ðŸ〜 - " 的字节序列是Unicode字符""的UTF8编码,FACE WITH STUCK-OUT TONGUE和WINKING EYE.(也就是说,它是表情符号.)

要正确存储此字符,您需要确保:

• 您正在MySQL连接上启用UTF8(即,SET NAMES utf8mb4在连接时使用选项,类似地启用它).
• 您正在运行MySQL 5.5或更高版本.
• 你的表的字符集是utf8mb4.

Answer 2

将 mysql 连接从“SET NAMES utf8”更改为“SET NAMES utf8mb4”

\n\n

在 PHP 中，使用 mysqli_set_charset 添加字符集，\n https://www.w3schools.com/php/func_mysqli_set_charset.asp

\n\n

$conn = mysqli_connect("localhost","my_user","my_password","my_db");\nif (mysqli_connect_errno()) {\n   echo "Failed to connect to MySQL: " . mysqli_connect_error();\n}\n\n// Change character set to utf8\nmysqli_set_charset($conn, \xe2\x80\x9dutf8mb4\xe2\x80\x9d);\n

\n\n

或者如果您使用 NodeJS，（这是额外信息，以防万一）

\n\n

db_config = {  \n    host: "localhost",\n    user: "user",\n    password: "password",    \n    database: "mydb",  \n    charset: "utf8mb4_unicode_ci"\n}\nvar conn = mysql.createConnection(db_config)\n

\n\n

另外，请确保表的列和表本身具有相同的 uf8mb4 编码。

\n\n

ALTER TABLE my_table CONVERT TO CHARACTER SET utf8mb4;\n\nALTER TABLE my_table\n   CHANGE COLUMN my_column my_column TEXT\n   CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;\n
