对于如何在使用.NET将数据插入MySQL数据库时跟踪我的bug,您能给我什么建议?

错误消息为:

MySql.Data.MySqlClient.MySqlException: Duplicate entry '26012' for key 'StockNumber_Number_UNIQUE'

对日志的审查证明库存编号26012尚未插入。

使用中的产品。

Visual Studio 2008。

mysql.data.dll 6.0.4.0.

Windows 7 Ultimate 64位和Windows 2003 32位。

自定义构建的ORM框架(具有源代码)。

从Access 2003数据库导入数据。

该代码适用于3000-5000件进口商品。

如果只导入记录本身,则在完整运行中导致问题的导入记录将正常工作。如果以不同的方式对要导入的数据进行排序,我还看到了其他记录上的错误。

已尝试导入,有交易记录也有交易记录。

已经从系统中注销了。

创建表的SQL命令:

CREATE TABLE `RareItems_RareItems` (

`RareItemKey` CHAR(36) NOT NULL PRIMARY KEY,
