10437 ERROR [2013-04-15 17:22:49]  

如题：错误并不是因为字段过长而导致出错的,

        1. 可能是因为数据库里的表设置的字符集不相同。

        2. 也可能真是数据库字段里数据库确实过长(我是遇到的这种情况)。

例如：在同一个数据库中，存在utf8的表，也存在gbk_chinese_ci的表。

解决办法：alter table `cms_activity_test` convert to character set gbk collate gbk_chinese_ci;(单独修改指定表的字符集)

补充：通过在网上查找资料，一般都是修改数据库Mysql的默认字符集和修改单个数据库的字符集

1。 在Mysql数据库目录下找到my.ini文件,然后Ctrl+F查找character-set,修改

[client]

port=3306

[mysql]

default-character-set=utf8

2. 修改单个数据库字符集,data目录下找到db.opt文件,然后修改

default-character-set=gbk
default-collation=gbk_chinese_ci

3. 用命令设置

mysql> SET character_set_client = utf8 ;
mysql> SET character_set_connection = utf8 ;
mysql> SET character_set_database = utf8 ;
mysql> SET character_set_results = utf8 ;
mysql> SET character_set_server = utf8 ;
mysql> SET collation_connection = utf8 ;
mysql> SET collation_database = utf8 ;
mysql> SET collation_server = utf8 ;

 4. 如果还嫌太麻烦了，就用一个蠢办法，如果整个数据库表不多且数据量不大的情况下，就将整个库导出，然后再去修改文件中字符集不一的表，最后再导入数据库。。。
