在EDMX中添加表时出现问题 [英] Problem in Adding Tables in EDMX

问题描述

我想在使用vs2010的edmx文件中添加表，当我尝试使用文档中描述的方法添加表/视图/sp时(在模型视图或设计器中单击鼠标右键->从数据库更新模型...) ...它没有在edmx中添加任何表格..请告诉我这是什么问题..我已经遍历网络，所有教程似乎都建议使用几乎相同的方法来添加表格.请指导.

在Advance中致谢

推荐答案

当您要添加的表或视图已经存在于模型中时，可能会发生这种情况.因此，不要使用更新向导中的add 标签 [ ADO .Net团队博客 [ ^ ]

This possibly happens when the table or view you trying to add is already exists in the model. So instead of using add tab from the Update wizard[^],use the refresh tab and see the effect. You can also check either the table or view exists in the model by opening in the model file in xml editor.
