An attempt to attach an auto-named database for file...failed. A database with the same name exi

I know allot of folks are having this problem and I tried lots of things but nothing works. I understand the problem is coping the SQL Express on another server is the problem - I just not sure what to do?

Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET Version:2.0.50727.42

This is the last statement on the Stack Trace:

SqlException (0x80131904): An attempt to attach an auto-named database for file e:\wwwdata\81d0493f\www\App_Data\TestDatabase.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.]
System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) +735091

I checked my server forum and they said I had to name a database:
Example: Database=(unique name);

But this didn't work either.

I just tried a simple web project that has only one database and one table in SQL Express with one sqldatasource and one datagrid. It works fine on my pc but when I use the copy function in Visio Studio 2005 Pro - I can't run the site on the remote server: www.myjewelrydirect.com

I tried coping the database manually. I tried disconnecting the database before I copy it. Below is my connection statement:

With all the comments in these forums - this must be a bug.

I have been working on this problem for over 2 weeks - HELP!

Since this is a web app, it is probably running under the ASPNET user account. Make sure that the ASPNET user, or what ever user your appliction is running under if you've set up something other than the default, has permissions on the directory where the database is located.

If the user doesn't have permissions to the directory, you can't attach the database.

An attempt to attach an auto-named database for file failed.

Hi,

I recently installed VS Web Developer Express Ediition and SQL Server Express and I'm doing the How To tutorials and I can't finish the basic data access walkthrough:

http://msdn2.microsoft.com/en-US/library/tw738475.aspx

Because I get an error like this (link for complete error below):

An attempt to attach an auto-named database for file C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\test.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

When I am setting up the data source for the gridview tool, everything works fine and the test query works fine, but then when I try to actually test the output in the browser with Cntrl+F5 I get this error.

I have been trying for 48 hours to find a solution on my own. I have googled, I have searched everything and I just am at a point where I think I need to ask someone for help.

Please help.

Make sure the file C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\test.mdf failedis not being used by other process. If it is the data file of some database in the SQL instance, you can't attach it by using AttachDBFileName property in the connection string.|||How do I do make sure it's not being used by an other process?|||

In other words, make sure it has not been attached in any SQL instance, and no other application is using it to create a connection.

|||

Thanks for your help so far.

But, how do I do that? How can I tell if another application is using 'it' to create a connection? I am using Visual Web Developer and SQL Server Management Studio Express and SQL Server Configuration Manager. Also when I hit 'Cntrl+F5' while in Visual Web Developer the page opens up in Firefox (my default browser).

I am not using the database for anything else. I have no idea how to monitor SQL instances. I am just beginning to learn these things and am working with tutorials that aren't working for me.

First of all, you aren't crazy or a no brained soul. This is not you. This is quirkiness in how Microsoft (and I am their biggest fan), in trying to make things easier, has somehow made CHANGES to your SQL environment difficult. I am working on sorting this out and creating some kind of a flow chart to troubleshoot all of this, but here are some insights in the meantime (Gurus - please correct me where I am wrong on any of this):

* ASPNETDB.MDF seems to occur for every ASP.NET application and should appear in the |DataDirectory| - which is normally(?/automatically?) APP_DATA

* I think it gets automatically created the first time you run your app (because it seems to me to not be there, then suddenly appear) but it may be under program control - I don't know

* if you have an instance that has been named ASPNETDB or ASPNETDB.MDF in your Sql database, connecting a new one will fail as a duplicate, so use Sql Management Studio to rename any such instances to something unique, like "c:\Webs\PartnerPortal\Northwind Traders\App_Data\ASPNETDB.MDF" instead of just "ASPNETDB.MDF"

* In my environment I have several named instances of Sql Server, including: "STARTEAM" (a Borland created named instance), "OFFICESERVER" "SQLEXPRESS" "MSSQLSERVER" and "MICROSOFT##SSEE" (Mobile edition). However, none of these are useful to me. I have uninstalled SQLSERVER (SQL 2000) and SQLEXPRESS. The one I NEED does not appear - which is the unnamed instance - SQL Enterprise 2005. To access that all I do is enter the server name, ip or .\

* I was using Microsoft Expression Web to edit the default connection string (and this is identical in Server Explorer in VS 2005 also). It asks you the provider. I was using the defaul and could not enter .\ as my Sql Server. I only had the other useless named instances and could not successfully connect. SOOOO I changed the provider. I had two choices:

"Microsoft Sql Server" and "Microsoft Sql Server Database File" (along with "Sql Server Mobile Editiion", etc).

* I changed my selection FROM "Microsoft Sql Server" TO "Microsoft Sql Server Database File". This allowed me to edit the server to be .\ when I went back to my connection string

* Then I changed the provider BACK and now I had the choice I needed! I think that the choice are coming from the registry and it got out of sync

Anyway, now I can connect. I think that connectionString updates the registry, where the problems lie.

*************************************************
Here is the skinny on troubleshooting connections:
*************************************************

(1) have you run aspnet_regsql from a command prompt at the c:\windows\Microsoft.net Framework v2xxx directory?

(2) did you create a virtual directory for your app and enable Asp?
(I have a separate memory pool for each version of Asp - another matter)

(3) did you change the Asp settings to the right connection string? The important things are: .\SQLEXPRESS or .\ or your named instance. If you do not use SQLEXPRESS then User Instance must be False

(4) are all of your instances of ASPNETDB.mdf named uniquely? (Ie: include a path)

(5) does IIS_WPG have sufficient rights to your web directory (this may not be true if you put your webs in your "My Documents")

(6) In VS2005, did you go to Websited-Asp config?

(7) Do you have the right settings in your Web.config?

(8) You must not have extraneous copies of Web.config on your path - they will be automatically referenced in the project. Ie, creating a backup in a subdir, is trouble.

(9) did you set your Default.aspx as the Startup page? (and the right project as the startup project if you have multiple projects?)

(10) did you use Server Explorer to try a different provider, update the registry choices of servers and to include your unnamed instance, per above?

Does Machine.config figure into this?

What have I missed or misstated?

To be honest, having done all of this, I still seem to have a web that I am still troubleshooting the connection for!

If anyone can correct, add or improve on the above, please do. What i would love to see is a Visio flowchart in a .pdf that could be emblazoned here. I can be reached at my gmail account of norisksoftware at gmail . com

|||Hi Bill, by default .NET 2.0 security providers(membership, profile, ect.) use a connection string named LocalSqlServer, to learn more details you can take a look at this article:

An attempt to attach an auto-named database for file failed

I have a problem when I want to open a page with the database record. This page is created in Visual Web Developer 2005 Express. When I try to open a page I get the following error message even though the connection between the database is ok:

An attempt to attach an auto-named database for file C:\Inetpub\wwwroot\membership\App_Data\aspnetdb.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I have a computer with Windows XP Professional running IIS 5.1 and ASP.NET 2.0.
Also I have SQL Express on my machine.
Does any one know how to resolve it.
Thanks Smile [:)]

Hi,

I guess you want to attach a user instance to SQL Server. But the path specified for the user instance is a server attached instance, which makes you able to view the data through the server explorer but won′t make you able to use the run the code, because at startup VS will try to create a user instance at the location specified (which is already occupied by the server instance database) and which will fail. The solution is to specify another folder to create the suer attached instance during the build of the code, thats all. That should make you able to run the build process as well as the code.

I have a problem with Microsoft SQL Server 2005 Express,

Is this a known bug in Microsoft SQL Server?
What should I do?

I thought that was the problem, but it isn't. I had already given the ASPNET
account full control when I had problems with a hit counter. That took me two
days to figure out...
Anyway,
With the info you have now what do you suggest I do?

An attempt to attach an auto-named database failed

An attempt has been made to use a data extension OLEDB that is not registered for this report se

I am using SQL Server 2005 Express along with the other Express reporting tools (VS Express). I am trying to report against an oracle database. I can design and preview the report however when I attempt to 'deploy' the report to a report server that is on the same machine I am developing on, I get the above error. Is this because I am running an Express version of SQL Server or is this an error?

Thanks,

Sam

Yes, the Express Edition only allows connections to local data sources with a limited set of data extensions. Not all types of data sources are supported in the Express Edition.

Am I missing something when trying to connect via ASP.NET 2.0?

I am at my wit's end trying to set up a simple test to retrieve some records from with ASP.NET and C#. I'm using the Express Edition on my development laptop. Whenever I try to run my application, I get the following error:

ERROR: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

I have researched this problem, and done everything I can find online to fix it but no avail. I have gone to SQL Server Configuration Manager and enabled Named Pipes and TCP/IP. I have stopped and restarted the server. Local and Remote connections (Both TCP/IP and Named Pipes) are enabled in the Surface Area Configuration. I added it to the Exceptions list of the Windows firewall. And yet nothing works. I can connect to it fine with Management Studio Express, but I am totally unable to connect to the database from within my code. I've spent probably about two weeks wracking my brain trying to figure this out; does anybody know what might be causing the problem and what could fix it?what does your connection string look like.|||"Server=ORPHEUS;Database=TestDB;User ID=sa;Password=mypass;Trusted_connection=False"

I've also tried specifyinig the instance of SQL Server (e.g. Server=ORPHEUS\SQLExpress) but that does not work either.
|||

If you're trying to connect to an instance name, then i'm pretty sure you have to specify it in your connection string.

Have you tried using the examples in the docs, like this one? http://msdn2.microsoft.com/en-us/library/ms247257.aspx

|||Well what do you know... turns out I wasn't specifying it in the right format.. I should have had it was "Database=ORPHEUS\\SQLEXPRESS".

Thanks a ton! Sometimes its the most obvious things that you end up missing...
