要将表重新添加到模型中，您首先需要删除模型中的表格。 （表的列表在[model.Store]树中可见（请参见 模型浏览器窗格，您可以从鼠标右键单击菜单中打开它。）

要完成的步骤：

要从数据库更新模型...，该表将出现在更新向导第一步的添加标签中。 p>

1. 在Visual

2. 在$中打开.edmx文件b $ b文本编辑器。


3. 搜索并删除
   xml实体元素（请参见下面的注释

要删除对模型中表的所有引用：

• 在 EntityContainer元素中，
  删除所有


• 在
  'EntityContainer'元素中，将'Name'属性设置为
  的'EntitySet'子元素
  设置为[TableNameToReAdd]值。删除所有
  'AssociationSet'子元素在存在结束元素的
  的ts中，其 EntitySet属性设置为
  的值是[TableNameToReAdd]。

I have a db with 5 tables. At the beginning, I've added those tables in, but then decided to remove some due to some relationship compile error.

Now, when i want to add them back, i'm opening the edmx file -> update model from database... I don't see those tables under add tab, but only under the "refresh" tab.

How can i add them back?

In order to re-add a table to your model you will first need to delete the table from your model. (a list of tables is visible in the [model.Store] tree (see 'Model Browser' pane- you can open it from right-mouse click menu). When you run 'Update model from database...' the table will appear in the 'Add' tab in the first step of the 'Update Wizard'.

Steps to complete:

1. Close your model in Visual Studio.
2. Open your .edmx file in a text editor.
3. Search and delete the xml entity elements (see notes below).
4. Open your model in Visual Studio.
5. Click Update Model from Database.

To delete all references to a table in your Model:

• In the 'EntityContainer' element, delete all 'EntitySet' child elements that have the 'Name' attribute set to the value [TableNameToReAdd].
• In the 'EntityContainer' element, delete all 'AssociationSet' child elements where an 'End' element exists that have their 'EntitySet' attribute set to the value [TableNameToReAdd].
• In the 'EntityContainer' element, delete all 'EntityType' child elements where that have the 'Name' attribute set to the value [TableNameToReAdd].
• In the 'EntityContainer' element, delete all 'Association' child elements where an 'End' element exists that have their 'Role' attribute set to the value [TableNameToReAdd].
