我有一个类型化的数据集，它是我使用数据集设计器和SQL 2005数据库设计的。我使用了SQL server资源管理器，只需将表拖到设计器中即可。
表中的一列是XML字段，设计器将其设置为System.String类型。类型化数据集设计器中没有XML数据类型的选项。
我将向该数据集添加一条记录，并为XML（字符串）列分配一个XML字符串。
当我尝试使用tableAdapterManager.UpdateAll方法更新SQL时，它会产生错误：“操作数类型冲突：SQL_variant与xml不兼容”
我不知道该如何处理这件事。我在网上找不到关于这件事的任何信息，这似乎是一件非常简单和常见的事情。有什么想法吗？
我找到了自己问题的答案。
正在更新的表存在于同一SQL server上的另一个数据库中（数据集中有许多表，但主数据库中不存在此表）。
有人在INSERT命令中添加了“databasename.dbo.tablename”，希望它在其他数据库上更新。显然，SQL server在处理XML类型时并不喜欢这样。
我将创建一个存储过程来处理这个表上的插入。
