SQL Server Express 2008 Using (local) In Connection String
May 18, 2010
Is it possible to connect to a SQL Server Express 2008 database in ASP.NET with a server name of (local) like "server=(local);integrated security=SSPI;database=DBNAME"? I'm working with another developer on a project and it's getting annoying having to have 2 different version of web.config because he is using SQL Server 2008 and (local) works, but I can't seem to get it to work with SQL Server 2008 Express locally. The database is located on the same computer as the .NET code in case that matters.

When i run in debug mode with this connection string:
Data Source=.;AttachDbFilename=c:New folderdbname.mdf;Database=dbname;Trusted_Connection=Yes;
everything works fine and i can access the database but once its published onto my iis it doesnt find the database?

I am fairly new to ASP.net - comming from a PHP / MYSQL background sometimes certain things in ASP.net confuse the hell out of me. In PHP - when writing an application you always connect to an external database server (MYSQL , PostGreSQL ) using a username and password and aswell a datbase server address(mostly localhost). Now with ASP.net i noticed that you can connect to an existing database within SQL server or you can create a local database in the App_Data folder.
The local database seems much easier to work with however my concern is what would you store in a local database? surely you cannot use it as a main database to store all your data(compared to a MYSQL database)? Secondarily with SQL server - when i login into SQL server management express , it uses "Windows Authetication" , i tried to select "Sql Server authentication" and enter my own username and password to login but that did'nt work. How do i deploy a database from SQL server to the web? - in MYSQL for example we would have a SQL dump file , which can be simply imported/exported from server to server.

I just installed SQL Server 2008 Management studio Express on my Vista machine.i tried connecting to local machine using :
.sqlexpress, (local)sqlexpress, or .SQLExpress, MyPCNAMESQLExpress
nothing is working, getting this error:
-----------------------------
Cannot connect to PC-NAMESQLEXPRESS. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

be it's a wrong place to ask the following question. Sorry for that. Our hosting provider has recently upgraded their database server from Sql Server 2005 to 2008 and I'm getting errors to connect with remote server from my development machine. Error Message "Invalid connection". Tried to find solution on net but couldn't find it.I'm using .Net 1.1. Though we've updated versions 2.0,3.5 & 4.0 but due to some certain circumstances I've no way to update it. It's a web based project. The following connection string works fine for Sql Server 2000 & 2005 but not for 2008.<add key="ConnectionString" value="Data Source=Remote Server's domain name;Initial Catalog=database name;User ID=user name;Password=surround;Persist Security Info=True;Pooling=false;Connect Timeout=45;" />Here Remote Server's domain name indicates to remote db server like: test.mysite4now.comdatabase name for example: test_surrounduser name like test_surroundpassword: surround.Can anyone inform me what's wrong with the above connection string to connect to Sql Server 2008.

I have a new server that I am attempting to deply my very first asp.net website on. I have installed SQL 2008 r2 and loaded my DB on it. I am able to access the server/DB through Visual Stuidio. At least I know i can call it from the webserver to my local PC.
For some reason I just cant get my we.config's connection strong right. It might even be the <provider> info that I have wrong. I am just too inexperienced to know for sure. My Web.Config is very short so I will post all of it here.
-- Code is posted at the end --
How do I modify my local project to use my webservers DB instead of the standard SQL Express DB? The only connection string
Machine.Config that points to the sqlexpress database. Again I lack the experience to know how to do this. I am using Visual Studio 2010 and SQL Server 2008 r2 on my local pc.

When I try to encrypt the "connectionStrings" section in the web.config file of my asp.net web application on Windows Server 2008, I'm getting the following error:
Administration utility (2.0.50727) to install and uninstall ASP.NET on the local machine. Copyright (c) Microsoft Corporation. All rights reserved. Note: This utility has limited capabilities on the Windows Vista operating system. It is recommended that you use the "Turn on or off Windows features" option of the "Programs" component of Control Panel to install or remove ASP.NET. It is also recommended that you use the IIS Manager component or the Appcmd.exe tool to configure ASP.NET applications.
The above information is followed by the list of valid options to aspnet_regiis.exe.
The command that I've used is:
aspnet_regiis.exe -pef "connectionStrings" "C:Usersuser1DocumentsMywebsite" -prov "DataProtectionConfigurationProvider"
But, the same command is working fine when used on a Windows Server 2003 machine. The problem is occurring only on Windows Server 2008 with IIS7.

After I installed Visual Studio 2008 Standard edition, then I upgrade "SQL Server Express 2005" to "SQL Server Express 2008 SP2". Process upgrading SQL Server Express 2008 was going succesfully (none of the process was fail).
But when I create a New Website I could not add a new item "SQL Server Database" into my website file. Because Visual Studio always rejected any new "SQL Server Database" by giving message below (underline):
This server version is not supported. Only servers up to Microsoft SQL Server 2005 are supported.

Background: I use SQL server 2005 developer edition and visual studio 2008. Visual studio 2008 is running on a local machine with Vista business edition. SQL server is running on a remote server using Windows server 2003. Both computers are within the same domain.
Problem: First, I used the server explorer to connect to the SQL server. Everything works as desired. Then I write code to do the same thing. I keep getting the following error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid)
However, I used the exactly identical connection string as the one used in the server explorer. So connection string should not be the problem. In addition, I tried the test code in MSDN, which tells whether my domainusername can flow the network. It turns out the user name is fine. I also went to the SQL server management studio and found the login for my computer is NVCWeihao while my computer login name is NVCweihao. I am wondering if this uppercase letter really affects the connection.

I am writing a web app for work. The users who are using this app will not be using the same connection string- for example, we have about 40 customers whose data resides in their respective database. The goal of this app is to be able to query the database for a given customer without having to go in and modify the web.config connection string (obviously, because that will change the connection string globally across users- I want the users to be able to have their own local connection string to be used by the app). is this possible?

I'm busy working on an ASP.NET Web Application (3.5) and can't seem to connect to a MySQL DB. I first created the entire application using a WinForms template and everything works 100%, but as soon as I move the exact same code to the Web Application, I can't connect anymore. Here's the code:
Code:
public class DBC {
OdbcConnection connection;
public bool CreateConnection() {
try {
string connFormat = "Driver={MySQL ODBC 5.1 Driver};Server=[SERVER];Database=[DBNAME];User=[UID];Password=[PWD];";
connFormat = connFormat.Replace("[SERVER]", Properties.Settings.Default.DBServer);
[Code] .....
As soon as I try to create the new OdbcConnection instance, I get the error:
Code: ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
As noted this works in a WinForms app, and even more strange is that I don't even specify a DSN name...
All I could find from reading through forums all over the internet is suggestions of downgrading the MySQL ODBC driver version, which I'd really rather not...

Would something be missing, not working, or confusing if I do this? First, install SQL Server 2008 Standard, and SP1. Then, install Visual Studio 2010 Professional, unchecking SQL Server 2008 Express option. Or would I need to fix any configurations afterwards?

My set up is as follows
IIS + SQL Server Express running on the same machine.
SQL Server Express has named pipe connections.
IIS hosts an ASP.Net website(v3.5)
ASP.Net site has web config entry to database using integrated security.In regard to this, how are the connections between the ASP.Net app. and SQL Server express handled? Does each user connect using the same login to SQL Express (think its NETWORK-SERVICE)? If 2 people hit the same web page at the same time how many connections are opened to SQL Express? Is it up to the setting in connection pooling? E.g. if connection pooling is set to 10 then in this example 2 connections are opened?Or is it that only one connection is used and users must wait for the previous user's webpage to finish all database operations before their request can be processed.

give me an example of the proper connection string for getting VS 2010 to use the aspnet database on my SQL 2008 server? The db is there, I just can't seem to get connected. Server name GUNSITESQL, mixed security. I want to logon with a SQL user logon id, the db name is the default aspnet.
Currently, the web.config file is the default.

Can you use a session variable in a web config connection string? So instead of:
Code:
<add name="ConnectionString2" connectionString="Data Source=ora;Persist Security Info=True;User ID=SA;Password=PASS;Unicode=True"
something like this:
Code:
<add name="ConnectionString2" connectionString="Data Source=" & Session(DB) & ";Persist Security Info=True;User ID=SPAR;Password=;Unicode=True"
