localdb

问题 If I run SQL Server Management Studio, and tell it to connect to (localdb)\v11.0, it knows about every database I've ever used, despite the fact that most of the the database files are long gone. If I ask it to delete one of these databases, it complains that it can't DROP the database because the database file is gone (duhhh). So, how do I clean up this mess and delete all of database references whose assicated database files are gone? Bob 回答1: In this situation, detach the database rather

问题 Is there any way so IIS could connect to LocalDB without using the NT SERVICE\NETWORK SERVICE user account. This account has not suitable permissions.

问题 I'm trying to do the Code First Walkthrough of the entity framework ( http://blogs.msdn.com/b/adonet/archive/2011/09/28/ef-4-2-code-first-walkthrough.aspx ). I have the latest SQL Server Express and when I check my versions available via command line ( sqllocaldb info ): I see localdbApp1 and v11.0.

问题 I have searched everywhere, however have not found a straightforward answer. I have deployed a WinForms C# .NET application, which uses a LocalDb SQL Server 2012 Express database. The database is thus a data file contained in the project. I would like to add some columns to a number of tables, and since the project is deployed at a lot of clients, I would like to send them a script, or a file of some sort, and once they run it, their database would have these changes. How can this be done?

问题 I have been developing an MVC 5 application on my local machine, and having just tried to public a test version to Azure, I have found this new error. My connection strings have no reference to a LocalDB, and I can't find anything in my code that wants to create or access a LocalDB. Yet I am receiving an error related to an attempt to create/access localDB: The connection string specifies a local Sql Server Express instance using a database location within the application's App_Data directory

问题 I'm building a .NET 4.5 (winforms) application that uses LocalDB to work with a local MDF file, using this connection string: Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\DB\DatabaseFile.mdf;Integrated Security=True;MultipleActiveResultSets=True When I run my application, the first SQL query takes some time to execute - nothing drastic, about 2 or 3 seconds. After that, all next SQL queries are executed instantly. I assume that the extra seconds during the first execution are

问题 I've been using some LocalDB databases (.mdf files). I've been the only one using those DB for a while, but more and more are using it now. Every time we use the app at the same time we have an error because we connect to the DB at the same time. Is there a way to allow simultaneous connections to an SQL LocalDB database? If not what is the best alternative assuming we will never have more than 5 people connecting at the same time? Here is the code i'm suing to acess my DB file : Public
