SQL Express 2005 Connection String Vs SQL Server (latest)
Oct 28, 2007
I'm a student at Boise State university and we're using SQL Express as part of one of our projects for ASP.NET programming. I liked it and I'm trying to use it to power a wiki that I'll be hosting from my home internet connection. The wiki is compatible with MSSQL server, but it won't connect to SQL Express.
I suspect that the problem is in the connection string, mainly because the apps we're developing for class use a connection string like:
<add name="AspNetForumConnectionString" connectionString="Data Source=localhostsqlexpress;Initial Catalog=gaming.forum.nxnw;User ID=*********;Password=*********;" providerName="System.Data.SqlClient"/>
and note the Data Source. The wiki I'm using is PHP based and uses ADObd to connect databases and has a driver for MSSQL, but not SQL Express (no surprise, really). I know just enough php to be dangerous to code and I've tried modifying the adodb-mssql.inc.php, but I can't seem to make the right change.
So, all that said, my question is: Is there a way to change what SQL Express 2005 will accept as a connection string? I've been looking, but I'm not even sure what the setting would be called.
Thanks,
Les

Hi, all. I am using VS.NET 2005 and SQL Server 2005 Express. I tried to use the following code to connect to a database named "AMSPROD" that I attached to SQL Server 2005 Express:
dbConn = new OleDbConnection(Data Source=.SQLEXPRESS;AttachDbFilename="C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataAMSPROD_Data.MDF";Integrated Security=True;Connect Timeout=30;User Instance=True);
dbConn.Open();
I got an error asking for provider with the above connection string, then I changed the conncection string to be like follows:
Data Source=.SQLEXPRESS;AttachDbFilename="C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataAMSPROD_Data.MDF";Provider=SQLNCLI;Integrated Security=True;Connect Timeout=30;User Instance=True
I got error: No error message available, result code: DB_E_ERRORSOCCURRED(0x80040E21)
Then I changed the Provider to be like: Provider=SQLOLEDB, now I am getting the following error:
Message: "Invalid authorization specification
Invalid connection string attribute"
Source: "Microsoft SQL Native Client"
StackTrace: " at System.Data.OleDb.OleDbConnectionInternal..ctor(OleDbConnectionString constr, OleDbConnection connection)
at System.Data.OleDb.OleDbConnectionFactory.CreateConnection(DbConnectionOptions options, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningObject)
at System.Data.ProviderBase.DbConnectionFactory.CreateNonPooledConnection(DbConnection owningConnection, DbConnectionPoolGroup poolGroup)

at ISESAMSData.DbConnections.MakeConnection() in C:\ISES\ISESCommon\ISESAMSData\DbConnections.cs:line 74"
TargetSite: {Void .ctor(System.Data.OleDb.OleDbConnectionString, System.Data.OleDb.OleDbConnection)}
Strange thing is, when I use the Connect To Database under Tool menu of VS.NET 2005, I could make the connection to this database. Then I copied this connection string to the code, the connection couln't be made. I feel very confused.
I am wondering if I need to add ASP.NET user to SQLExpress. But I don't know how to do it?
Can anyone please help me out! Many thanks!

I try to use this conn string but it is not working I think the problem is with the provider
DataBaseSource = "Provider=SQLOLEDB; Password=sa2006; User ID=sa;Initial Catalog=coupon; Data Source=YAELSQLEXPRESS;"
I get error message

or maybe it is a sacurity problem

Hi, I have installed on my laptop SQL server 2005 Developer edition, I can change ANY of the settings of the SQL server and OS.
I am writing code with a team using continuous integration where the connection string is the following:
"Provider=SQLNCLI;Server=.SQLEXPRESS;Database=Secret;Trusted_Connection=Yes;"
is there a way (create an alias,rename server, other?) to make my local dev SQL server accept the connection string above, as at the moment I have to rename the connection string every time before checking in code and after downloading the latest version from the code repository.
any advice or tips will be greatly appreciated
Thanks
JW.

I am using SQL server express 2005. I can drag and drop a grid control on to my web form and choose the data source to point to a SQL server database. Then datais nicely displayed on my web form.
Now I need to manually create my connection to the database as I need to read from a text file and then populatea database table with those values I read from the text file. I have not had any success with this though and I am stuck and need some help.
Below is my C# code and I list the web.config code where my connection string is stored.
Note that I can trace into the C# line of code below. If I then do a "Quick Watch" on "myConnection" in the debugger, the followingerror message is displayed:
ServerVersion 'myConnection.ServerVersion' threw an exception of type 'System.InvalidOperationException' string {System.InvalidOperationException}
So I don't know what the problem is here. If someone can help me out I would be forever thankfull
C# code:
SqlConnection myConnection = new SqlConnection(ConfigurationSettings.AppSettings["TheDividerConnectionString"]);
Here is the connection string as defined in the web.config file:
<connectionStrings> <add name="TheDividerConnectionString" connectionString="Data Source=BVCOMPUTERSQLEXPRESS;Initial Catalog=TheDivider;Integrated Security=True" providerName="System.Data.SqlClient" /> </connectionStrings>

Hello,
I'm working with classic ASP and am having a terrible time trying to get a proper connection string working with my database. Could someone please advise me on how to get the following code to connect to my database (which is using Windows Authentication)?
If fileSize > 0 Then
' Connection string
Dim connStr
connStr = "Provider=SQLNCLI;Server=Dell-LaptopSQLEXPRESS;Database=Upload;Trusted_Connection=yes;"
' Recordset object
Dim rs
Set rs = Server.CreateObject("ADODB.Recordset")
rs.Open "Files", connStr, 2, 2
Right now the error I'm receiving is:
"SQL Network Interfaces: Error Locating Server/Instance Specified
Also, I'm using II7 with Vista.
Thanks,
Trix.

Hi there
I'm trying to connect to sqlserver express using dreamweaver mx. TYhey are both installed on the same machine (win 2000 server),
What I am confused about is the user and password, I have installed the example Northwind database and attempting to connect to it.
In dreamweaver I add a connection (SQL Server connection) , a template shows and I add the data:
Persist Security = false;
Data Source =mycomputersqlexpress;
Initial Catalog = Northwind;
User ID = ?
Password = ?
What do I put in the User ID, Password and how do I configure sqlserver (I'm using Server Management Studio).. As I said I already have Northwind under the database section? but don't know how to set permissions.. Thanks

Hey,
I have a asp.net 2.0 app that has a sql server express backend. I have been scratching my head for weeks trying to find a good wasy to encrypt my connection string. I store the string in web.config (which in itself is in theory "safe" because it's not servable) and I have scoured the web to try to find a simple way to encrypt the connection string. Even using user store would require running aspreg_iis.exe on the host with a command prompt (which clearly I cannot do). It seems that everyone's solution requires running a command prompt executable on the server.
So I am left to wonder what everyone else does. I am not comfortable using just the web.config because a determined hacker could get to that info. Then again, a determined hacker could get into any system , I guess. There are no credit card #'s stored in this app, but in theory there must be a way. I run all access to the db through stored procedures with permissions, for whatever it's worth.
Thanks in advance!

All --
Please help.
I have some questions about connection strings.
BACKGROUND...
Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005.
Note that I do not want to use the "Attach a database file" type of connection string.
Note that I am using the site http://www.ConnectionStrings.com as a reference.
Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
QUESTIONS...
(A) What exactly does the error in Item 4 mean?
(B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string?
(C) Are there any alternatives?
(D) What do you suggest?
Please advise.
Thank you.

Hi,
I have just uninstalled SQLEXPRESS and installed the 180 day trial SQL server 2005 enterprise edition.
I have since started to have problems with my ASP.Net Configuration Tool., can not connect to the database.
I think that the connection string in my machine.config file is incorrect, before installing I had,..:
datasource=./SQLEXPRESS,....
So i decided to change that part to the following. Would anybody know what I have put in the datasource part for the SQL server 2005 enterprise edition? At the moment I tried SQLSERVER2005 but that is incorrect,..
<add name="LocalSqlServer" connectionString="data source=./SQLSERVER2005;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" />

What is the impact of the differences in the following 2 connection strings:
Initial Catalog=xxx;Data Source=xxxxxx;Trusted_Connection=True;
Driver={SQL Server};Server=xxxxx;database=xxx;Trusted_Connection=yes;
To outline the differences I'm concerned with are
Missing Driver on first string
Difference in Trusted_Connection parameter (true vs. yes)
Initial Catalog vs. database parameter

I downloaded SQL Server 2005 Express and some sample databases (incl. Adventureworks_data.mdf), but when I try to Add Connection in VS 2005 to point to this db and use the Test Connection button, it gives the error:
---------------------------
Microsoft Visual Studio
---------------------------
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
---------------------------
I've tried setting the data source as either "Microsoft SQL Server Database File" or "Microsoft SQL Server", but get the same error.
Any tips on verifying SQL Srv Express is installed correctly? Any ideas on how to solve this problem?
Thanks in advance.

Hi everyone!
I am new to visual studio 2005 and sql server 2005.
Up to now i was using visual studio 2003 and ms access.
When i wanted to create a web application that communicates with
an access database, i just had to take the *.mdb file and put it
into a specific folder inside my application's folder and then use
Server.MapPath on the connection string (so it can run on any pc).
Now, i want to do the same with sql server 2005 and visual studio 2005.
I use the connection string: "Server=MYSERVER;Initial
Catalog=test_db;Integrated Security=SSPI".
My problems are:
1) Can i just take the *.mdf file put it inside the App_Data folder like i did on access?
2) What should be the connection string so that my application can run on any pc (with sql server 2005)?
Thanx in advance guys!

I am having trouble connecting to SQL Server 2005 Express using ASP.NET written in VB.NET (1.1 Framework) in VS2003. I am trying to programmatically connect to the SQL Server. Since this is a redistributable web application and I don't want to rewrite the connection string every time I distribute a copy, is there any way to automatically get a connection string without prompting the end user for one? I can get the server name and the data base name, but I don't know how to get a username. It returns an error saying SERVERASPNET can't log on. Can anyone help?

This is a bit of a cross-post from the VS 2005 Forum, but we don't have a forum dedicated to SQL Server 2005...This is on my test machine running Windows XP Pro SP2 (NTFS),I have an existing SQL 2000 database located on a separate hard drive dedicated to data -- the e: drive.I just installed SQL Server 2005 Express, in the default installation directory (c:Program FilesMicrosoft SQL Server) and I cannot connect to that database on the e: drive. Named pipes, error: 40 (Remote access services are not installed by default).I don't want the database physically located on the c: drive.I've been looking all over for the solution for this, and can't find it.Advice or direction to reference materials would be appreciated.Tinker

Hello everybody
I`ve installed Visual C# 2005 Express edition for evaluation reasons. After that I also installed Microsoft SQL Server 2005 Express edition also for evaluation. I then downloaed the installation scripts for the Northwind database and tried to install them.
Unfortunately, every time I try to execute these scripts I get the error :
C:SQL Server 2000 Sample Databases>osql -E -i instnwnd.sql
[SQL Native Client]Named Pipes Provider: Could not open a connection to SQL
Server [2].
[SQL Native Client]Login timeout expired
[SQL Native Client]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.
I`ve enabled named pipes in the configuration utility, but to no avail. This is also no firewall problem. It just can`t connect to SQL server. Anybody with similar problems or a possible remedy?

Is it possible to connect to a sql server express over internet or not ?
- I am using a win2003 sp1 server. Freshly installed.
- The server is directly connected to internet.
- For the purpose of the test, I stopped the windows firewall and the IPSec service.
- I stopped SQL server Browser service.
- I find a free port (here : 1401)
- I activated TCP/IP protocol in SQL Server Configuration Manager, and I have selected 1401 as the TCP port in the IPAll sextion of TCP/IP protection (and I remove the '0' of the dynamic TCP Port).
- Restarted SQL server express...
In the sql server log, I get the message "Serveur Server is listening on [ 'any' <ipv4> 1401]"
But I never get an answer from the server.
sqlcmd -S ip_of_the_server, 1401 -U username -P password is working fine if launched on the server. But I always get a timeout error from any PC. Same with a telnet on port 1401.
Any idea ?

Hi
I got an access 2002 application front end with a sql server 2005 express back end. Some of my clients are having some difficulties. After using the application for a while, some of the users are finding that the system just hangs up. It usually happens after the front end application has been running for about an hour (sometimes sooner and sometimes later). There are perhaps 1 to 5 concurrent users and I have checked to see if there are any firewalls stalling it (I think I check all of them)- Is there any way that SQL Server 2005 express could be caused to just stall- This even occurs with the odd laptop. All the appropriate protocols are enabled as well. These databses are not very large.
ANY HELP WOULD BE GREATLY APPRETIATED!!!
Thanks

I just installed SQL Server Management studio express. I am trying to remotely connect to a SQL Server Express 2005 remotely. I was given the server name, user name and password, and used SQL Server authentication. It connected fine, and I was able to get at the intended database.
I then went to ODBC data sources to add this SQL server using SQL authentication. I entered the server, user and password, and I got a nebulous "could not connect" error. I thought is may be because I still was connected in SQL Server Management studio express, so I closed it and tried again with the same error. I then reopened SQL Server Management studio express and tried to reconnect, and got the same nebulous error, and have not been able to connect since.
I tried rebooting and reinstalling SQL Server Management studio express, but had the same result. Does anyone have any idea what I may have done and how to undo?
Thanks,
Steve Colino
