在MySQL中将JSON值设置为文本变量时出错 更新：这里是JSON代码的粘贴库。如果有人能告诉我为什么MySQL拒绝将此作为文本变量来阅读，以及如何绕过它，我将不胜感激：

我这里有一个奇怪的。在Windows上运行8.0.18。我的环境都是utf8mb4和utf8mb4\u unicode\u ci

问题是MySQL拒绝将附加的JSON文本读取到文本字段中，无论定义了什么字符集，在尝试将文本变量设置为代码时总是出现以下错误：

错误1366（HY000）：第1行“json_text”列的字符串值“\x96 2019…”不正确

很明显，MySQL不喜欢文本中有一个字符，但是我应该在什么字符、什么位置以及如何“擦洗”该文本以使其被接受

这发生在尝试将JSON分配给文本值的行上：

set json_text= JSON_EXTRACT((injason), CONCAT('$.', 'in_JSON'));

以下是完整的代码：

DROP PROCEDURE IF EXISTS `sp_jason`;
DELIMITER //
CREATE DEFINER=`root`@`localhost` 
PROCEDURE `sp_jason`(
    IN parameterName VARCHAR(10)
)
COMMENT 'schema_version_applied_to: v1.0.0'
master_block:BEGIN
 DECLARE json_text text CHARACTER  SET latin1;
 DECLARE injason JSON;

DECLARE exit handler for SQLEXCEPTION, SQLWARNING, NOT FOUND
 BEGIN
  GET DIAGNOSTICS CONDITION 1 @sqlstate = RETURNED_SQLSTATE, 
   @errno = MYSQL_ERRNO, @text = MESSAGE_TEXT;
  SET @full_error = CONCAT("ERROR ", @errno, " (", @sqlstate, "): ", @text);
  SELECT @full_error;
 END;

有人知道问题出在哪里吗@刻痕你在外面吗？：）

也许这个答案会帮助你：

十六进制96可能是en破折号（–）的拉丁1编码。但是你已经指定了 如果CSV文件是utf8编码的（或utf8mb4），则utf8无法理解此字符

计划A:更改文件。（这可能不太实际。）

计划B:告诉MySQL文件是latin1（而不是utf8）。然后MySQL将其正确转换为utf8编码E28093

“排序”与排序和比较有关；“字符集”与“编码”有关

可能包含查询的文件编码不正确。

因此，我通过将文本粘贴到中解决了这个问题，这表明JSON结构良好且为绿色，但它表示“转义未转义的chracter”。可悲的是，它没有告诉我角色在哪里或是什么，更疯狂的是，'（例如\'）的3个角色转义之前就已经完成了。所有这些都没有任何意义，但很明显MySQL在管理某些类型的文本时遇到了严重问题，甚至试图将该文本定义为utf8或utf8mb4，甚至拉丁语1，对这样的问题都没有影响，这是荒谬的。不幸的是，我没有从这个“修复”中学到任何东西，仍然不知道为什么会发生错误，也不知道为什么我的好友（MySQL DBA）能够在完全相同的代码导致我端错误的情况下毫无问题地运行代码；但是现在，当我通过json处理站点运行它时，它神奇地被修复了（记住，问题是将它设置为文本值，最终与json格式无关）。我在MySQL中遇到的每一个问题中，95%都与字符集或排序问题有关。我在MSSQL中从未遇到过这样的问题。我后悔选择了MySQL。

很有趣；根据您的建议，我将如何更改“文本”？如您所见，我们试图提取到的文本变量已经定义为Latin1；如果这就是问题所在，那不是解决了问题吗？或者您的意思是将核心JSON变量设置为utf8mb4的默认值以外的其他值？我该怎么做？此外，正如您所见，这不是一个文件，而是一个在存储过程本身中定义的输入“字符串”（作为JSON变量）。进一步信息，如果我将大JSON字符串设置为文本值Latin1（例如，将@hugeJason更改为var_jason（作为文本字符集Latin1）它给出了完全相同的错误，因此这肯定是字符集的问题-但最终这对我来说毫无意义。整个字符集/UTF8垃圾从来都不是MSSQL的问题。我猜您必须在@hugeJason变量转换为JSON之前更改其编码，以删除无效字符s、 文档中还说：JSON文本应该使用ascii、utf8或utf8mb4字符集进行编码。其他字符编码被隐式强制为utf8mb4。（。不过，我很高兴能够帮助您！问题是即使我将文本变量声明为字符集utf8mb4，并将该值设置为“大JSON字符串”（就像你在上面的例子中看到的）导致了错误。据我所知，MySQL根本不想“修复”字符（或编码）。我不知道如何解决这个问题。不幸的是，我无法重现这个问题，但这可能会有帮助：SET@hugeJason=SELECT CONVERT（BINARY CONVERT（@hugeJason使用拉丁语）使用utf8；（）
