mysql - 在coldfusion中处理MySQL NativeError Code 1366和SQLState HY000

Question

请找到以下错误的堆栈跟踪的最初几行:(sl列是我在存储过程代码中使用的)

Incorrect string value: '\xC2\x80\xC2\x99t ...' for column 'sl' at row 1 at 
com.mysql.jdbc.SQLError.createSQLException(SQLError.java:946):946 at 
com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:2985):2985 at 
com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1631):1631 at 
com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:1723):1723 at 
com.mysql.jdbc.Connection.execSQL(Connection.java:3283):3283 at 

and so on..

存储过程代码，CODE II，从下面提到的CODE I调用:

经过研究，我发现人们在谈论某种 UTF8 格式。但如果这就是实际问题，那么为什么我会得到上述结果仅在少数情况下出错而不是每次都出错？请指教。

Answer 1

更新:从 MySQL 5.5.3 开始，还有 UTF8mb4 which is often recommended over UTF8 .

<小时/>

听起来确实与unicode有关。该列的字符集和排序规则是什么？请参阅INFORMATION_SCHEMA.COLUMNS看法。

就错误而言，我想这将取决于您要插入的字符(可能会改变)。严格遵守error message description ，即 er_truncated_wrong_value_for_field，听起来像是输入包含无效字符，或者输入字符串的解释被截断。同样，这听起来像是某种字符集问题。

更新:

假设您收到有效的 UTF8 字符串，这似乎确实是字符集问题。尽管我的测试数据库默认为字符集 UTF8，但我可以通过创建一个使用两种不同字符集的小表来重现该错误:LATIN1 和 UTF8。然后插入一个小UTF8 string进入两列。插入 UTF8 列工作正常，但 LATIN1 列失败并出现错误:

Incorrect string value: '/xD0/x9D/xD0/xB0 /xD0...' for column 'ColDefaultCharset' at row 1 ...

尝试将字符集更改为 UTF8，我认为 INSERT 可以正常工作:

  ALTER TABLE YourTable MODIFY YourColumnName VARCHAR(500) CHARACTER SET utf8;

表:

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;

示例文本:

На берегу пустынных волн
Стоял он, дум великих полн,

程序:

CREATE PROCEDURE `testWithUTF8`
(
  IN `sl` VARCHAR(500)
)
BEGIN
    INSERT INTO testTable (ColUTF8Charset)
    VALUES ( sl );

END


CREATE PROCEDURE `testWithLatin1`
(
  IN `sl` VARCHAR(500)
)
BEGIN
    INSERT INTO testTable (ColDefaultCharset)
    VALUES ( sl );

END

代码:

<cfprocessingdirective pageEncoding="UTF8">
<cfsavecontent variable="text">
На берегу пустынных волн
Стоял он, дум великих полн,
</cfsavecontent>

<!--- Note: For CF10, use cf_sql_nvarchar --->
<cfstoredproc procedure="testWithUTF8" datasource="MySQL" result="procResult">
    <cfprocparam cfsqltype="cf_sql_varchar" value="#text#">
</cfstoredproc>
<cfdump var="#procResult#">

<cfstoredproc procedure="testWithLatin1" datasource="MySQL" result="procResult">
    <cfprocparam cfsqltype="cf_sql_varchar" value="#text#">

DSN 设置:

• 驱动程序:MySQL 5
• 高级设置 > 连接字符串:characterEncoding=UTF8
