我在使用带有平面文件的SSIS进行输入和sql输出时遇到了问题，因为数据类型不匹配。检查以确保它不是这样的简单。
此外，您的帖子中没有包含大量有关出现问题的信息，因此很难判断出数据库存在问题或者您遇到了什么样的错误？您是否尝试过使用SSIS gui而不是以编程方式执行此操作？

你现在可能已经解决了这个问题...... :)如果是这样，请告诉我们。
在Flat File版本中，缺少目标连接分配后的以下行。这可能没有多大帮助（因为你的输入列缺失）但是我们修复它并看看我们得到了什么错误......
InstanceDestination.SetComponentProperty("OpenRowset",
DestinationTableNameInternal);
InstanceDestination.SetComponentProperty("AccessMode", 0);

此代码错误：
conMgrSource.Properties["RowDelimiter"].SetValue(conMgrSource, "{CR}{LF}");
conMgrSource.Properties["HeaderRowDelimiter"].SetValue(conMgrSource, "{CR}{LF}");
此代码可以正常工作：
conMgrSource.Properties["HeaderRowDelimiter"].SetValue(conMgrSource, "\r\n");
