Sam Abraham Software Engineer/Architect: Putting Customers First
With most of our systems pre-configured with SQL server, it was only today that I ran into this issue with my fresh installation instance of SQL Server 2008 R2.
I had just created a new SandBox DB to experiment with some aspects of Entity Framework 4.0, but as I was saving foreign key changes to tables I had already created I got the following error:
Saving Changes is not permitted. The changes you made require the following tables to be dropped and re-created
Figure 1 - Unable to save table schema changes error
With some research, I found my answer in SQL Books Online: Any Schema changes made to a table would require disabling the default option of “Prevent saving changes that require the table to be re-created”. To resolve this, from SQL Management Studio, go to: Tools->Options->Designers->Table and Database Designers. We would then need to uncheck the “Prevent saving changes that require the table to be re-created” check box as shown below and Voila!
Prevent Saving Changes that require table re-creation
