[Solved] The Backend version is not supported to design database digrams or tables.
I Came across this error when I got to work on some other machine with SQL Server Management Studio 2008 R2 installed.
This error is thrown up when I tried to modify the design of a table by right-clicking on a table and selecting the “Design” option.
Solution:
- Check Database version using “SELECT @@VERSION”
In my case it was SQL Server 2012 SP1. - Update the SQL Server Management Studio to the version of the SQL Server.
That’s all!
