在nhibernate中调试“字符串或二进制数据将被截断”错误

我正在调试应用程序中的间歇性截断错误。我的日志中的错误如下:

System.Data.SqlClient.SqlException: String or binary data would be truncated.
The statement has been terminated. Generated: Tue, 02 Nov 2010 03:55:18 GMT

NHibernate.Exceptions.GenericADOException: could not insert:
[DataModel.Product][SQL: INSERT INTO [Product] (Fields) VALUES (?, ?,...);
select SCOPE_IDENTITY()] ---> 
System.Data.SqlClient.SqlException: String or binary data would be truncated. 
The statement has been terminated.    
at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)

请注意,该错误不为引发该错误的SQL提供参数值,只提供占位符: (?, ?,...) . 有没有办法从NHibernate那里得到这些?像这样:

try {
    ...
    Session.Flush(); // throws
}
catch (GenericADOException ex) {

    // want to get the bad parameter values, 
    // so I can re-throw a more helpful exception
}
