Connecting To SQL Express Through VB
Oct 28, 2006
Hi all,
I have SQL server express edition 2005 installed on my computer and using VB in MS Access to run some queries. The VB function looks something like this..
Dim dataRS As New ADODB.RecordsetDim cnnSQL As New ADODB.ConnectionSet cnnSQL = New ADODB.ConnectioncnnSQL.ConnectionString = "Provider=SQLNCLI;Server=.SQLExpress;Database=TestDB;Trusted_Connection=yes;" cnnSQL.Properties("Integrated Security").Value = "SSPI"cnnSQL.OpendataRS.Open "SELECT dbo_Table_1.* FROM dbo_Table_1", cnnSQL, adOpenStatic, adLockOptimistic
The code fails on the last line with message
"Invalid object name 'dbo_Table_1'"
(yes, I verified that the table actually does exist in the DB)
I must be doing something wrong with the connection string but all the things that I've tried so far haven't worked.. Can anyone offer any suggestions?
Thanks in advance,

Hi all,
I want to do SQLCLR by Connecting to SQL Express User Instances in Management Studio via VB 2005 Express and I have read the following articles and books:
(i) Connecting to SQL Express User Instances in Management Studio in http://blogs.msdn.com/sqlexpress/archive/2006/11/22/connecting-to-sql-express-user-insta...
(ii) Managing SQL Server Express with SQL Server 2005 Management Studio Express Edition in http://www.microsoft.com/technet/sql/2005/mgsqlexpwssmse.mspx
(iii) Chapter 16 - Going Beyand Transact-SQL: Using the SQL Common Language Rutime (SQLCLR) in Microsoft SQL Server 2005 Express Edition for Dummies
(iv) Chapter 21 - Working with the Common Language Runtime in Microsft SQL Server 2005 Programming for Dummies
(v) Chapter 4 - Introduction to Common Language Runtime (CLR) Integration in Programming SQL Server 2005 by Bill Hamilton.
I want to create an SQLCLR project "HelloWorld" by Connecting to SQL Express User Instances in Management Studio via VB 2005 Express. But I am still not sure how to get it started, because I do not understand the following things:
(1) Pipe Name for a User Instance, (2) Enabling (or Disabling) the CLR by using Transact-SQL, (3) Creating a Transact-SQL script, (4) Creating an Assembly, (5) Creating a backup device, etc. I need to see some simple examples of SQLCLR by Connecting to SQL Express User Instances in Management Studio via VB 2005 Express. Please help and tell me where in the websites I can find them.
Thanks in advance,
Scott Chang

Really confused ... I created 2 tables in a VB Express program (which went well). Problem is that I can't see/find those tables with MSME. I don't really understand how to connect the MSME to where the tables are. I created the tables under My DocumentsData and they are DBapp.mdf + DBapp_log.LDF and the tables are Items and Preferences. The VB application can "see" the tables OK.
Do I need to move the tables to C:Program FilesMicrosoft SQL ServerMSQL.1MSQLDATA (like the Adventureworks installation which I haven't done) or what?
Please help a newbie
Thanks

I Can connect to a sql 2005 express database, from visual basic 6.0, locally with no problem.
The connection string looks like:
cnWEB.ConnectionString = "Provider=SQLNCLI.1;Integrated Security=SSPI;" & _ "Persist Security Info=False;" & _ "AttachDBFileName=" & sPath & "viper.mdf;Data Source=.sqlexpress;"
where the path is the path to the database file viper.mdf.
How would I modify the connection string to remotely connect to a sql 2005 express database running on a web server running 2003 server???
Thanks

SQL Express 2014 was installed to support reporting for an application. I can connect to the server using the server name without any issue. When I run “select @@version”, I get SERVERNAMESQLEXPRESS, but I can’t connect to the server with SERVERNAMESQLEXPRESS. This is throwing off one of my script when trying to connect to the server.My script connects to the server using SERVERNAME for default instance or SERVERNAMEINSTANCENAME for named instance.

It is well documented and I am fully aware of the fact that remote connection protocols are disabled by default in Express. That being said, I have and application that has been working fine that used Express as a back end on my work network. We have been using it in a LAN environment (ie. all of the nodes are on the 192.168.xxx.xxx segment of the network). Recently, I have had to deploy this app to another facility in a different city that is on a different segment (ie 192.178.xxx.xxx adresses). There is connectivity in the LAN, but not over the WAN.
With all that being said, is there any know limitation to Express that would prevent me from establising a database connection across the WAN, eventhough I have a perfect setup in the LAN environment.
Any feedback is greatly appreciated.
Thanks

I have a small networked application, using sql server 2005 express. I am using datalinks and I have configured the TCP/IP to 'Enabled' on the server and I have configured the firewall. I have one computer connecting to the database through sql authentication (using a specific name and password). However I have another machine, using the same configurations, but it has a AMD 64 processor. I get the "Sql Server does not exist or access denied" message.
I would greatly appreciate assistance.

Hello,
I'm a newbie who is trying to create a connection to the server in my website application and I keep getting the following 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 enabled TCP/IP and Pipe in the configuration and restarted the engine and server but I still get this error and it's stressing me out. Below is the code for the app. Any help would be greatly appreciated. Thanks

Folks.
I just moved my domain to GoDaddy.com. When I run my website locally, everything works fine.
When I ftp it to my server space on GoDaddy.com, I get a "remote connection" error. Does anyone have an example of a connection string I should be using to connect while on the server?
Thanks!

Hi,
Please assist with the following.
How do I connect to SQL Server Express in VS2003? "Do I still use using System.Data.SqlClient;"?
What would the connection string be in the code? The following does not work.
try { string connectionString = "server=localhost;uid=webserver;pwd=wordpass;database=dbMV;"; // create a new SqlConnection object with the appropriate connection string SqlConnection sqlConn = new SqlConnection(connectionString); // open the connection sqlConn.Open(); // do some operations ... // close the connection sqlConn.Close(); } catch(Exception err) { Response.Write(err); }

I'm new to MSSQL. At my work place, I'm using MSSQL and using SQL Query Analyzer to run queries and view all my database tables and structures.
Now, I can work remotely at home for the time being. So, how do I get SQL Query Analyzer and be able to connect remotely to my database at work?
I've downloaded SQL Server 2005 Express and it comes with SQL Server Management Studio, which looks similar to SQL Query Analyzer. The problem is though, how would I remotely connect to my database server at work? Is it possible to do this using SQL Server 2005 express?
One thing I was advised to do was configure the TCP/IP Port number from 1433 to 1435. However, I do not see an option to configure that nor do not know how to connect remotely (I do have the IP, User, and Pass).

Hi All,
I'm having trouble getting at SQL Server 2005 Express via ASP code.
I'm using the following connection string in my ASP code:
Set objConn = Server.CreateObject("ADODB.Connection")
objConn = "Provider = SQLNCLI;" & _
"Data Source = .SQLEXPRESS;" & _
"Initial Catalog = myDB;" & _
"User ID = DB_reader;" & _
"Password = a#koddkobn5;"
I keep getting the error:
Microsoft SQL Native Client (0x80004005)
Login failed for user 'DB_reader'. The user is not associated with a trusted SQL Server connection
I have made sure that the user exists in SQLEXPRESS and that server Security is set to SQL Server and Windows Authentication mode.
Can anyone think of anything I'm missing or that I should try?
We've lost our SQL Server admin and I'm trying to develop locally using Express while we hunt for a new admin.
Thanks so much for any assistance you have time to offer.
Very best,
Thom Cox

I am having major issues connecting to SQL Server 2005 Express from Visual Basic 2005 Express, which I have tried on multiple PCs but to no avail. Can somebody please explain to me what I'm doing wrong?
1) I install SQL Server 2005 Express and Visual Basic 2005 Express (With .NET framework and SQL native client of course)
2) I open SQL Server using Management Studio and going in with windows authentication. It automatically sets the log on name to computernameSQLEXPRESS.
3) I create a new database called Test and add one table to it
4) I go into Visual Basic 2005 and create a new project.
5) I go to the projects application settings (Properties - Settings).
6) I set up a new connection string, choosing SQL server as the conection type and then on the Connection Properties window it asks me to select the mdf file for the database. I choose the file Test.mdf from the directory C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData
7) I click on Test Connection.
When I do this on two out of the three home PCs I get the error:
Unable to open the physical file "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf".Operating system error 32: "32 (error not found)".
An attempt to attach an auto-named database for file C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
The third PC gives me a different error:
Cannot open user default database. Login failed. Login failed for user 'DAVEDavid'.
I get the same errors when I try to use a connection string inside the code directly. Does anyone have a clue as to why these errors are occuring? Do I need to set up security or something else on the database first, or is there another reason? If anyone can please help me get to the bottom of this or provide a web address where I can get the answer (step by step instructions on how to connect) then I would be most grateful.

I'm having issues talking to Vista Sql Express, but selectivly.
The following diagram shows you what works, and what doesn't :
http://www.craznar.com/junk/sqlissue.png
As you can see, the Vista/Express server is running - has all the required connectivity enabled, however we cannot talk from the Windows Server 2003 SQL to the Vista SQL.
The error that is given suggests issues with remote access enabling on Vista - but this is working alsoVista's firewall turned off (We can connect to it).
All machines are on the same subnet, behind the same firewall - Neptune and Headoffice are on a domain, Neptune points to Headoffice for DNS, Headoffice forwards DNS requests to the same DNS all other machines use.
File sharing and Ping work from Headoffice to Neptune ... just can't get SQL connection to work.
Any help appreciated.
Thanks

Hi
I hope this is the right place for this question.
I'm using SQL 2005 Express on my local machine, I can connect and do all I need to.
But when I transfered my database to my remote server I cannot connect (I changed the connection string to suit).
<add name="ClubSiteDB" connectionString="Data Source=xx.xxx.xx.xx,1786;Network Library=DBMSSOCN;Initial Catalog=xxx;User ID=xxx;Password=xxx;" providerName="System.Data.SqlClient"/>
I have checked the connection string passsword etc, and all are correct.
I have tried SQL Server Management Studio, aspnet_regsql.exe etc and all give the following 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: TCP Provider, error: 0 - No such host is known.)or
System.Web.HttpException: Unable to connect to SQL Server database. ---> System.Data.SqlClient.SqlException: 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: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)
I have used the surface config to enable TCP/IP and named pipes.
Any Ideas?

How do I get rid of this error message when tring to log into my web site user account stored on the default ASP.NET 2.o generated database on my local computer?
Server Error in '/FundACure.org' Application.
Cannot open user default database. Login failed.
Login failed for user 'LANBOYASPNET'.
Where "LANBOY" is the name of my computer. I am logged in as myself "LANBOYKEVIN" My web page is trying to log into the server using the name "ASPNET" which I assume is a standard ASPNET user name.
I thought it was failing because I needed to grant access to this user in the server, so I added the account for the server. Same problem.
So I thought I needed to create this user in my Windows XP user list. When I tried it said "this user already exists" even though it isn't displayed in the list. That is when I realized that it is a standard user established by ASP.NET. It is probably supplied in the C# code through a base class.
So, how do I get this DB to connect? Is the user missing, or is it that my connection string is wrong?

I have an ASP application which is currently using a SQL 2000 Database, attaching via SQLOLEDB. I am getting ready to migrate my ASP application to .NET using SQL Server 2005 Express. The only problem, is that I am unable to connect successfully from my ASP applcation to my DB under SQL Express.
I have taken all of the steps that I have read, including the blog by Ming Lu. I still cannot be through.
I have included both the messages that are thrown and comments about the drivers and connection strings.
I have enabled TCP/IP and Named Pipes for SQL 2005 EE. I have also included the executable, port 1433, port 135, etc. in the firewall exceptions.
I have defined the DB in ODBC using both the Native Sql driver and the SQL Driver. Connection authentication is via SQL Server Authentication.
If anyone has any input, I would be grateful.
Error Messages:

Good afternoon,
I have written a .NET app that kicks off an unattended install of SQL Server Express Advanced. After the install, the same app tries to connect to SQL Express adn run a script that creates a database plus a few other things.
However, the problem I am having is that my app cannot connect. I get the error:
"An error has occurrred while establishing a connection to the server. This failure may be casued by the fact that under the default settings SQL Server does not allow remote connections."
However, the unattended install goes great. No problems there. I know this because I can Open SSMS, run queries, created DB's, etc. I also know that it is not the remote connections issue because the unattended install is set to allow remote connections (both names pipes and TCP/IP).
So, why can't i connect? I don't need to reboot after the install do I? Please tell me i don't...and please tell me it is something simple I am overlooking.
Thanks...
