How to quickly update the Entity Data ADO.NET data model?

Question

I am using the ADO.NET Entity Data Model in my C # project. There is an Entity Data ADO.NET data model that is created in the database in my project. How to quickly update the ADO.NET entity data model based on database changes? I delete the model and then create a new one. I believe there is an easier and faster way.

Answer 1

Right-click on the model builder and select "Update Model from Database" and a dialog box will appear. Click "OK" and your model will be updated.

FYI, I am using EF 4.0 and I skipped the earlier version, so I can’t tell you what it is in VS 2008.

Answer 2

Updating a model from a database does not work very well. At least in VS 2008 / C # 3.5. I cannot delete old columns, etc.

Answer 3

I always Ctrl-A (to select all), click Delete, and then create a model from the database from scratch - the update simply does not work correctly in many cases. At least in EF4 / VS2010, which I am developing in / s.

Answer 4

Perhaps this helps ... Model Update Wizard (entity data model tools)

Answer 5

Right-click - update the model from the database.

Answer 6

You should open your Model.edmx after this right-click on the properties. Now select (Update Model from Database) and it will show you another panel with a tab. You can select "Add", "Update" and "Delete". in your current situation you should choose Refresh. then select “Tables-> dbo-> and the name of your table in the database, and then click“ Finish. ”This will update the table.

but sometimes you can see in your model that something went wrong because the column is not in the correct position. to solve this, simply right-click on the column name and select “UP” to move it up or “DOWN” to tear it down.

I hope this helps.
