Thank you for contacting us.
If I am understanding correctly, your scenario is such that you change the connection string so that the model targets the backup version of your database. When you try to update, the wizard shows that you are adding a table.
If this is correct, the reason for the behavior could be that there are differences between the model and the database
and the Create Database option
is selected on the Select Changes screen
of the Update Database from Model wizard
. In case you need to update the database without attempting to add the table you need to select
the Migrate Database option.
Then you will be able to see what are the changes in the model, that you attempt to push to the database.
If the error you mentioned still occurs after updating the database, please tell us what is the operation that causes it - are you executing a query, or something else?
I hope this helps. Feel free to get back to us if you have any more questions.
