请在下面找到错误的最初几行堆栈跟踪：
（列sl是我在存储过程代码中使用的那个）
Incorrect string value: '\xC2\x80\xC2\x99t ...' for column 'sl' at row 1 at

经过研究，我发现人们在谈论一些UTF8格式。但如果这是实际问题，那么为什么我会得到上述内容 只有少数情况的错误而不是每次都错误？请指教。
答案 0 :(得分：2)
更新：从MySQL 5.5.3开始，还有UTF8mb4 which is often recommended over UTF8。
听起来它与unicode有关。该专栏的字符集和校对是什么？请参阅INFORMATION_SCHEMA.COLUMNS视图。
至于错误是零星的，我想它将取决于你插入的确切字符（可能会改变）。严格地离开error message description，即er_truncated_wrong_value_for_field，听起来输入包含无效字符或输入字符串的解释被截断。再次，它听起来像某种charset问题。
<强>更新
假设您收到的是有效的UTF8字符串，它似乎确实是一个字符集问题。虽然我的测试数据库默认为charset UTF8，但我能够通过创建一个使用两个不同字符集的小表来重现该错误：LATIN1和UTF8。然后在两列中插入一个小UTF8 string。插入UTF8列工作正常，但LATIN1列失败并显示错误：
字符串值不正确：＆＃39; / xD0 / x9D / xD0 / xB0 /xD0...'对于专栏 ＆＃39; ColDefaultCharset＆＃39;在第1行...
尝试将字符集更改为UTF8，我认为INSERT将正常工作：
ALTER TABLE YourTable MODIFY YourColumnName VARCHAR(500) CHARACTER SET utf8;
表格
CREATE TABLE TestTable (
ID INTEGER NOT NULL AUTO_INCREMENT
, ColDefaultCharset VARCHAR(100) CHARSET LATIN1 NULL
, ColUTF8Charset VARCHAR(100) CHARSET UTF8 NULL
, PRIMARY KEY (ID)
) ENGINE=InnoDB DEFAULT CHARSET=LATIN1;
