I have an MVC 4 website using .NET framework 4.5 that works fine at first. It allows me to login and go about my business adding, deleteing and editing records. As such, it is obviously initially connecting to the database without a probelm. However, if I leave it inactive for a while and come back at a later time, and then click a link to a page that shows data from my database, I get the following error:
The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider cannot automatically create the database file.
The website works fine on my localhost, but not when I host it online. I use shared hosting for this. I've done extensive searching online and found lots of people getting the same error, but they don't seem to have a website that works initially and then suddenly stops working. The solutions I've found online say something along the lines of:
add these two lines to your web.config file
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="Data Source=p3swhsql-v15.shr.phx3.secureserver.net; Initial Catalog=DatabaseName; User ID=****; Password='****';"/>
by default the .net site is trying to find your database in the local filesystem in this case would be the app_data subfolder under the wwwroot directory. simply removing the connectionstring and replacing it with the database connection solves the issue. My example utilizes an SQL db on godaddy's server. however i'm sure you can replace the connection string with the appropriate string for your connection. good luck and i hope this helps anyone that may be having this issue
What my program seems to be doing is using the online database when I first login, and then reverting to trying to use the database in the local filesystem once the session timesout. This is very frustrating. My web.config file looks as follows:
<connectionStrings>
<remove name="DefaultConnection"/>
<add name="DefaultConnection" connectionString="Data Source=winsqls01.cpt.wa.co.za;Initial Catalog=SportFantasySA;Persist Security Info=True;User ID=*****;Password=*****" providerName="System.Data.SqlClient"/>
</connectionStrings>
Please help. I'm desperate to get this working. I understand that it can't create the sql express database in the hosting space, that's why I'm using the connection string for the database on my hosting company's server.
If you have hosted it on Godaddy go for the connection string as
<providers>
<remove name="AspNetSqlMembershipProvider" />
<add name="AspNetSqlMembershipProvider" connectionStringName="LocalSqlServer"
..other attributes here... /></providers>
<connectionStrings>
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer"
connectionString="Data Source=xxxx; Initial Catalog=xxx; User ID=xxx; Password=xxx;"
providerName="System.Data.SqlClient" />

My project is working perfectly on local host but I am trying to host it on iis and following error is showing
Steps which I have tried so far:
1.checked my connection string which is
<connectionStrings>
<remove name="umbracoDbDSN" />
<add name="umbracoDbDSN" connectionString="Server=EIL-IT-360-39\SQLEXPRESS;Database=umbraco_16_6;Integrated Security=true" providerName="System.Data.SqlClient" />
</connectionStrings>
2.Using window authentication to login into my DB.
I have also refrered given sites but could not found desired solution:
Umbraco cannot start. A connection string is configured but the Umbraco cannot connect to the database
Umbraco cannot start after switching to local SQL database
Check which identity your website is running under in IIS:
open IIS
got to Applications Pools in the tree on the left
find your website in the list
go to Advanced Settings
switch the Identity to Network Service rather than ApplicationPoolIdentity
I believe this is the user which runs the website. If this doesn't work, you may want to check that your selected Identity has access to the database.
It looks like a permissions/connection issue. Usually this is because either the IIS server can't see the machine "EIL-IT-360-39" (try using the machine's IP address instead). Or the windows authentication isn't working.
If you're using integrated authentication, the site will be connecting as your application pool identity account. You need to make sure that the application pool account has access to read and write to your database. There is a tutorial here on how to do this: https://msdn.microsoft.com/en-us/library/bsz5788z.aspx
Thank you all for your help..my problem is now solved ..though it solved by adding a new user with some password in my ssms and then adding same in connection string as
<add name="umbracoDbDSN" connectionString="..database=umbraco_16_6;user id=sa;password=*****" providerName="System.Data.SqlClient" />
then,my umbraco password was not accepted at login screen[even though I haven't made any changes in that password]..for which I tried to update hashed password and other options..but none of those worked for me..
Then I have had a backup of my DB..which saved my project..and now I am able to login into my Umbraco site as well as hosted it successfully on my network.
please provide the same user name and password that u created while instating umbraco Db.and yor visualstudio connection string should be like
<connectionStrings>
<remove name="umbracoDbDSN" />
<!--<add name="umbracoDbDSN" connectionString="server=PALPIN-022\SQLEXPRESS;database=Databasename;user id=UmbracoDbname;password='umbracodbpassword'" providerName="System.Data.SqlClient" />-->
<!-- Important: If you're upgrading Umbraco, do not clear the connection string / provider name during your web.config merge. -->
</connectionStrings>
note: password should in "''" double quotes inside single quotes.
I added a new Sql Server Database to my project with the name: ShDB.mdf. It is located in a App_Data folder.
It contains a Table which has some columns. I could add some numbers to the table and then show them in a gridview on my localhost.
This is what I have in the web.config:
`<configuration>
<connectionStrings>
<add name="ShConnectionStr" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\Javad\Desktop\Sharj\App_Data\ShDB.mdf;Integrated Security=True;User Instance=True"/>
<add name="ConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ShDB.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>
<compilation debug="true" strict="false" explicit="true" targetFramework="4.0"/>
</system.web>
`
Here is the vb.net code which I used:
Dim connectionString As String = ConfigurationManager.ConnectionStrings("ShConnectionStr").ConnectionString
And it works properly on the localhost test but when I published the website and uploaded the files on a web hosting service to test, I counter an error. How may I fix it? I think I should change my Data source path but I don't know how because its my first experience. Thanks to any help. you can see the error page here: http://www.kaj.somee.com/SL.aspx
Sql Server is either not installed or not running on the web host, or you don't have access to connect to it.
ASP.Net does not by itself know how to use your *.mdf database. It needs a running instance of Sql Server to talk to. It will tell Sql Server to load (attach) your database file, and then send queries to the Sql Server service for execution.
Do you mean you already uploaded the website to a web hosting service, but not the database?
If so, your application may not communicate directly with your database which is actually in your local machine.
You probably need to upload the database to a database hosting service as well (eg.SQL Azure, etc).
You may need to figure out the IP address/Server Name of your database hosting where you have uploaded. These information you can probably get in for the service provider. From there you should be able to connect to the database with the correct configuration.
I am currently reading Manning's "ASP.NET MVC 4 in Action" book and trying to get the first example to work.
Within my test application, I built a simple Model and created some Views. I then imported "SQL Server Compact" using NuGet.
When I finally try to run the application I get the following error:
Invalid value for key 'attachdbfilename'
This occurs on every interaction with the Database (SELECT or other CRUD operations) I am running. Any ideas?
Though, I am bit late to respond to this question but I was facing the same issue and I resolved it by modifying the connection string like below
<add name="MovieDBContext"
connectionString="Data Source=.;Initial Catalog=Movies;AttachDbFilename=|DataDirectory|\Movies.mdf;Integrated Security=True"
providerName="System.Data.SqlClient" />
Hope this would be helpful for others too.
I tried finding a solution for this particular error without success.
Fixed it in the end by updating the .Net Framework 4 to 4.0.2. Patch and details can be found Here is the link
Hope it helps
I think the problems here is string in web.config is not correct
According to your set up sql, the string will work if you set something similar like this
<add name="MovieDBContext"
connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=Movies;AttachDbFilename=|DataDirectory|\Movies.mdf;Integrated Security=True"
providerName="System.Data.SqlClient"
/>
Data Source=.\SQLEXPRESS; --> sometime, it will be Data Source=.;
after that, you need config right to access FOlder App_Data
If u test on Window 7, right click folder. property
Security tab -> add user network Service with full right
Go to section of Web.config and modify the section to the following to get SQLServerCE4 to be used:
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlCeConnectionFactory, EntityFramework">
<parameters>
<parameter value="System.Data.SqlServerCe.4.0"/>
</parameters>
</defaultConnectionFactory>
</entityFramework>
I guess problem occurs only when using SQL Express on .NET Framework v4.0.30319 anyways
SQL Server Express Local Database Runtime support in SqlClient is added in .NET Framework update 4.0.2 read - http://support.microsoft.com/kb/2544514
Alternately use connection string similar to this
<add name="EmployeeDbContext" connectionString="Data Source=.;Initial Catalog=Employees;AttachDBFileName=|DataDirectory|\Employees.mdf;Integrated Security=True"
providerName="System.Data.SqlClient" />
<add name="myconstr" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|mydata.mdf;Integrated Security=True" providerName="System.Data.SqlClient" />
above connection string was giving an error but as soon as added"\" before the name of my database the error got resolved.
Try this:
<add name="myconstr" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\mydata.mdf;Integrated Security=True" providerName="System.Data.SqlClient" />
You are using SQL Server Compact 4.0:
Be sure you have installed SQL Server Compact 4.0.
Install VS 2010 SP1 Tools for SQL Server Compact.
Change your connection string to:
<connectionStrings>
<add name="MyModelDBContext" connectionString="Data Source=|DataDirectory|mymodel.sdf" providerName="System.Data.SqlServerCe.4.0"/>
</connectionStrings>
Right click on controllers folder and -> add -> controller
Type:
YourController
MVC-Controller with read/write ...
MyModel
new datacontext -> APP.Models.DatabaseContext
Here is a blog post I found about that error. It is a bit old, but uses the express version of sql server. MSDN Link
That blog post talks about expecting the server name of the sql database to be a local address and not /sqlexpress
There is also this blog post that talks about having an incorrect connection string. So maybe check your connection string to the database. and your problem could be there.
Facing the same issue, I have looked over my connection string and found that "UNC-style" paths e.g. \\MyServer\MyDBServer are not allowed, one has to use the MyServer\MyDBServer syntax for a remote host or the .\MyDBServer syntax for locally hosted DB Servers.
I'm trying to deploy an asp.net application to a server using a SQL Server instance for the ApplicationServices membership database.
The problem is, I'm getting an error that says
The connection string specifies a local Sql Server Express instance
using a database location within the applications App_Data directory
I got this error when I initially tried to deploy the aspnetdb.mdf itself with the application.
I got this error when I then scrapped that plan and decided to do a web.config transform so that in Debug I use the Express database, but on Release the connection string goes to SQL Server.
I got this error again when I decided out of curiosity to remove all references to the express database from the code, so there could be no possible way anything would be looking for the Express database. No luck.
Does anyone have any ideas about this? I have deleted and re-installed the web site in IIS each time, noting that there is no App_Data being deployed and no mention of the .mdf file in web.config - to no avail. It still thinks there's a connection string telling it to look for a SQL Server Express database :/
Edit: Here's the connection string I'm using. Pretty standard, I think, but I could always be wrong.
Data source=HERP;Initial Catalog=DERP;Integrated Security=True
Could the error refer to the default connection string from the machine.config file (the LocalSqlServer one)? This could be happening, considering that the default membership provider uses this connection string:
The following default membership element is configured in the
Machine.config file [...]:
<membership>
<providers>
<add name="AspNetSqlMembershipProvider" [...]
connectionStringName="LocalSqlServer" [...]
Do not forget to clear the connectionStrings first:
<connectionStrings>
<clear />
<add name="LocalSqlServer" connectionString="Data Source=(local);Initial Catalog=aspnetdb;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
I purchased a Windows shared hosting account on godaddy that came with 2 MSSQL databases. I setup one to hold my site data and the other installed aspnet membership schema to store site members. The site works perfectly even displaying data from the 1st database. However when I try to login or register I get this nasty error
Exception Details:
System.Configuration.Provider.ProviderException:
The SSE Provider did not find the
database file specified in the
connection string. At the configured
trust level (below High trust level),
the SSE provider can not automatically
create the database file.
Ive gone through my web.config and there's nothing wrong with my 2 connection strings. It seems godaddy has a problem with using 2 mssql databases simultaneously when 1 is for membership.
Does anyone know a solution or a workaround?
I hope my experience benefits every one. Basically if you want to avoid aspnet membership problems on godaddy always use "LocalSqlServer" as the connectionstring. i.e
<providers>
<remove name="AspNetSqlMembershipProvider" />
<add name="AspNetSqlMembershipProvider" connectionStringName="LocalSqlServer"
..other attributes here... />
</providers>
Then create the "LocalSqlServer" connectionString...remember to remove it first
<connectionStrings>
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer"
connectionString="Data Source=xxxx; Initial Catalog=xxx; User ID=xxx; Password=xxx;"
providerName="System.Data.SqlClient" />
</connectionStrings>
I ran into same problem and am using MVC3. Above solution works but with some other changes in MVC3. It took me long time to figure it out so if anybody has similar issue in MVC3 it might help them:
Search for "connectionStringName" in web.config and replace the name with connectionStringName="LocalSqlServer"
Also under connectionstrings make sure
-To add (As this is important for all who are using shared hosting it will replace machine.config LocalSqlServer connectionstring with yours.)
-Keep your current connectionstring (In my case it is FilmiDb, this is required for you to connect to the database in EF model. Without this you will get errors.)
<connectionStrings>
<remove name ="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="Data Source=.\SQLExpress;Initial Catalog=SofilmiDb;Integrated Security=SSPI" providerName="System.Data.SqlClient" />
<add name="FilmiDb" connectionString="Data Source=.\SQLExpress;Initial Catalog=FilmiDb;Integrated Security=SSPI" providerName="System.Data.SqlClient" />
</connectionStrings>
