• Unique Constraint Nhibernate.

  - by Will

  I have a object with a Nhibernate mapping that has a surrogate ID and a natual ID. Since of cource the natural ID is uniquely constrained a insert query will fail if the object is already in the database with the same natural ID. My solution for this has been to manually check to see if natural IDs are in the database before trying to insert. Is there a way to specify Nhibernate to do a select before insert on natural Id's/Unique Constraints?

  I have a very large table in my database and I am starting to get this error Could not allocate a new page for database 'mydatabase' because of insufficient disk space in filegroup 'PRIMARY'.

• DB Designer creates compound primary key

  - by Jon Winstanley

  When adding relationships to a database model in DB Designer 4, a composite primary key is being created every time. So every foreign key I add, I get an extra key added to a composite primary key. I think I must have changed a setting as I don't remember it doing this in the past. Does anyone know how to turn off this feature as I prefer to use a single surrogate primary keys in my database tables?

Time was when that meant VBA (which is still an option), but the managed code derivative VSTA (I think) seems to have withered on the vine. What is now the best choice for an embedded scripting language on Windows .NET?

• Unit of Work Pattern in .Net

  - by Jazza

  Does anyone have any concrete examples of a simple Unit of Work pattern in C# or Visual Basic that would handle the following scenario? I'm writing a WinForms application in which a customer can have multiple addresses associated with it. The user can add, edit and delete addresses belonging to the customer before the customer is saved back to the database. Therefore, at the time of saving, all the original addresses need to be deleted from the database and the new addresses added in a single transaction.

• Set of Tools to optimize the performance in general of SQL Server

  - by Dave

  Hi, I know there are things out there to help to optimize queries, ect... but is there anything else, something like a full package that can scan your database and highlight all the performance issues, naming conventions, tables not properly normalized, etc? I know this is the job of a DBA and if the DBA is good, he shouldn't need a tool like that, but sometimes you start a new job, you get in charge of an existing database and the DB is a mess, so you don't know where to start... Thanks to everyone Dave
