I recently installed Visual Studio and SQL Server 2012. I\'m wondering if I\'m missing something because the Database Designer doesn\'t seem anywhere as friendly as the old
We can no longer do queries visually inside Visual Studio 2012. For those who enjoy typing they can type their queries. This makes joining multiple tables a lot of fun. For those who don't like typing SQL Server Management Studio still has a visual query editor. The other option is to use an older version of Visual Studio.
The SQL User Instance designers have been replaced with SQL Server Data Tools (SSDT) designers.
Where this is going is that Microsoft is encouraging developers to move towards using a separate Visual Studio project for the database, rather than having it stored as an asset within your application project.
This project system works by synchronizing a set of Offline database object declarations (written in T-SQL) with a physical database during project build.
The replacement designers seem a bit peculiar because they inherit much of their behaviour from those designers used in the offline database projects.
You can read more about SSDT here: http://msdn.microsoft.com/en-us/library/hh272686(v=vs.103).aspx
Of course, there's no reason why you can't use those Online designers to edit your database: instead of clicking Save when you make changes to an object, click Update. This will apply changes directly to your .mdf asset.
Or perhaps do what I do and simply use SSMS to edit your databases instead :)
