SqlExpress Instance In Connection String Instead Of Full Sql 2005
Sep 27, 2006
Hello,
I had started my project with the express edition, then I switched to the pro one. The problem is that in my webconfig I still have .SQLEXPRESS and I don't know how to modify that to use the full version of Sql server.
<add name="MyConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|MyDataBase.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
When I look at the surface area manager I can see that I have 2 instances running : MSSQLSERVER and SQLEXPRESS.
When starting Sql Server Management Studio I can connect to 2 servers: NEWDELL and NEWDELLSQLEXPRESS.
And when I try to replace SQLEXPRESS by MSSQLSERVER in the connectionstring, then it doesn't connect.
I remember having lost connection already when playing with all these tools, so I pay attention now ! That's why any help would be really appreciated !
Thank you.

The box I am trying to connect to is running two instances of SQL Server.
There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'.
I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" />
However, I am having trouble connecting to the Default SQL Server 2005 instance. I have tried:
<add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" />
but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used:
<add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" />
but this doesn't work either.
Am I mssing something here? Any help much appreciated
Thanks...

I am working on a C# stored procedure for SQL 2005, and i've uncovered a couple questions.
First a description of the procedure:
I have a series of equations taking place to calculate a score based on activities in which the user participated in, that will give them an over all grade or rating. The calculations currently take place in the database, and I am moving this from T-SQL to C# CRL.
1. In order to connect the stored procedure to the database I use a SqlConnection and a SqlCommand to execute either dynamic sql or a stored procedure to return data to a data reader. Is there an easier way to connect to the database? In SSMS if i open up the query it knows what database i am connected to. Do I have to make a sql connection in C# stored Procedures?
2. I have multiple functions within the main C# Stored Procedure that I'm working on. This ends up requiring Multiple Active Recordsets. I must set this withing the connection string. Seeing as I'm using a named instance of SQL 2005, I now must put the userid, password, and server name into the code. Is there a more secure way to connect to SQL Server in a C# Stored procedure that allows MARS?
3. I encryped the connection string, and put it into the assembly, I wrote a decryption class, and in the procedure itself everytime I need to refrence the connection string, I call it, decrypt it, and pass it along. But my code to decrypt the connection string is in the compiled DLL, if the server was ever compromised the encrypted connection string and the key to decrypt it are sitting in the DLL. Is there a config file that I can use for C# Stored Procedures?
4. If I have to keep the connection string in the file, then I need to change that per environment. Example I have 3 test environments before production. So I would need to change the connection string for each file. That may be fine for one procedure, but what if I have 20, that will quickly get of hand?
5. Along the security lines, can the assembly for a C# Stored Procedure be called from outside the assembly? From a command prompt, or by a maliceous program? Or could it be called directly by a .NET application instead of going through a T-SQL Stored Procedure that is using
WITH EXECUTE AS CALLER
AS
EXTERNAL NAME [PROJECTNAME].[CLASSNAME].[METHODNAME]

So i get this version of sqlexpress up and running and i copy all my databases over on to it. Redo my Logins for te server and then add the the DSN to ODBC admin console.
And still no good >:_( this is the error i get:
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open database "publicSite" requested by the login. The login failed.
So i know im doing somthing really stupid.
So heres what i got:
ASP connection srting looks like this:
<%
// FileName="Connection_odbc_conn_dsn.htm"
// Type="ADO"
// DesigntimeType="ADO"
// HTTP="true"
// Catalog=""

#!perl
I am having difficulty converting my CGI(perl module) connection from mySQL to SQLexpress. Does anyone know what the connection string should look like?
Listed here is my current connection string. I'm trying to get this done this week. Please email me if you have an answer in addition to posting.
$dbh = DBI->connect("DBI:mysql:database=$var{database};host=$var{server}","$var{root_username}", "$var{root_password}",{'RaiseError' => 0, 'PrintError' => 0});
Much appreciated,

Hi,
I have an ASPNETDB.MDF (asp.net membership/profile db) that was generated for SQL Express, it has user information I need to keep.
I have SQLExpress and full SQL Server 2005 running on the server. I want to remove SQL Express from the server.
So can I simply do a backup of the SQL Express membership db and restore it to full SQL and change the connection string in my app or
do i need to run the membership wizard on full sql and then do the backup / restore?
Or is there another way.
Thanks

What happens when you install a SQLEXPRESS instance on a machine that already has SQL Server 2005? Will the SQLEXPRESS still run in the limited mode or will it sense that an full standard version of SQL Server 2005 is already present and just "upgrade" itself?
On the otherhand, how do I "upgade" an existing instance of SQLEXPRESS to a full version of SQL Server 2005 standard edition without uninstalling and installing the standard edition. If I have both the instances then will the SQLEXPRESS be freed from its limits?
Thanks,
Vikram

Whenever I use "User Instance=True" as in the connection string below, I get an invalid connection string error. If I take it out, the connection string generates other errors.
"Provider=SQLNCLI.1;Integrated Security=SSPI;Persist Security Info=False;User Instance=True;AttachDBFileName=|DataDirectory|DbName.mdf;Data Source=.\sqlexpress;"
Removing User Instance=True always eliminates the invalid connection string message.
BTW, I tried both Data Source=.\sqlexpress and Data Source=.sqlexpress.

This has me totally baffled. I have a default instance of SQL Server 2005 on a server and I installed a second instance on the same server. It worked fine until I rebooted the server. Now I cannot connect to the second instance. The error message mentions remote connections but I'm not trying to connect to the instance remotely. The entire error message is below. Has anyone come across this?

Now you all must admit that, if your somewhat new to this databasing, It's a ***.
The source for my application is Visual Web Designer 2005 Express
It is an ASP.Net driven site with membership roles and all the good stuff.
the latest theory is that I need to change the provider config in the web.config file from AspNetSqlProvider
to something else. Most of my complications and frustrations come from GoDaddy and no access to the
shared server (understandibly).
I hope I gave enough info for help and not too much..

Hi, I am deploying my web through a web hosting services which provides SQL database support. I got following errors whenever I try to open my webpage,which never happen when I run my web on the local machine. I have my connection string configured in my web.config as below:
<add name="ArtHouseConnection" connectionString="Server=serveripaddress; Integrated Security=True; Database=arteh3_database;User Id=username;Password=password;" providerName="System.Data.SqlClient"/>
<add name="ASPNETDBConnectionString1" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
This is the source code where error was generated:
public static class ArtHouseConfiguration

Basically I need to know how to detach a db from a user instance of SQL Express from inside a VS2005 windows forms application.
The application is project oriented and the design calls for each project to be stored in its own separate .mdf file. When the user wants to switch projects the application will detach the current database and attach a different one, containing the data for the desired project.
I have this working fine with the default (.SQLEXPRESS) db instance, but I am having a problem getting the code to work with a SQL Express user instance (also part of the specification).
I am using the SMO library to do the Detach, and this works fine with the default instance, but for the user instance I am unable to connect to the necessary (user) instance of the db server.
I have tried selecting the instance name from dm_os_child_instances on the default instance and using the dynamically generated instance name to create the Server object. I get a good instance name, but when I create the Server object, the connection fails. I have also tried issuing "sp_detach_db" on the user instance, but this fails because the db is in use.
Any ideas would be greatly appreciated...

What if I give my named instance as SQLEXPRESS? I read that SQLEXPRESS

Hello,
I am using the following connection string to connect to SQL Server 2005 Express Edition installed on my local PC.
string sqlstr = "Server=(local);Database=MyDB;User ID=sa;Password=sa;Trusted_Connection=False";
And it gives me the following error. The string works fine in computer with SQL Server 2000 instance but fails with 2005. The string also fails for "Server = localhost".
However the string works very fine if I use the name of Server 2005 i.e ./SQLExpress
===================================
Cannot connect to (local).
===================================
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) (.Net SqlClient Data Provider)
------------------------------
Error Number: 2
Severity: 20
State: 0
------------------------------
Now the main problem is that, of course I could use a named instance, but since I am embedding the Connection String in a dll file so that any user can use it to connect it to the local instance of the SQL Server 2005 installed in his/her computer, I need to use "server = localhost". Doesn't SQL 2005 support this. If yes, where could i find option to enable it?
I have enabled every option available in surface area configuration for SQL Server 2005, but nothing seems to help out. I even use local as well as remote connections using both TCP/IP and named pipes.
Can nyone help me out?

I am installing SQL 2005 Express on several laptops (IBM Thinkpads and Dell latitudes) and I've noticed that doing the exact came configuration options with the exact same file, the IBM thinkpads just take the Machine name for SQL Server, while the Dells take MachinenameSQLEXPRESS. I am wondering how I can get it to just take the machine name on the Dells.
Thanks a lot

I installed SQL Server Express and SQL Server manager, then tried to start manager. SQL Service is running, but SQL Manager attempt to connect to SQL Server instance times-out even though I correctly identify instance as SQLEXPRESS? Everything seems to be normal - both SQL Server and Manager are on a single Windows XP home machine. Any suggestions. Thanks

Hello,
I am getting the following warning in the Application Event Log:
The configuration of the AdminConnectionTCP protocol in the SQL instance SQLEXPRESS is not valid.
The warning is logged by the SQLBrowser service.
This is happening on Windows 2003 server with SQL Server Express 2005. On the same machine SQL Server 2000 is installed.
I am currently unable to connect from remote clients to the instance of SQL Express and I believe it has to do with this warning (I've tried all the usual remote connection troubleshooting without success - enabled protocols, SQL Browser Service running, there is no firewall on the server, I disabled firewall on the client when trying to connect).
Does anyone know how to resolve this issue?
If you need additional information please let me know.

I executed the above project in my local PC (with Adiministrator previlidge/use) that is in our LAN/Network system and I got an error: SecurityException was unhandled - Request for permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'failed. First, I have a question: is this problem related to the remote connection to SQLEXPRESS? Second, I do not know how to solve this problem. Please help and answer my first question and tell me how to solve this problem.
Thanks in advance,
Scott Chang

I have SQL 2005 and I wanted to write a little program in Visual Basic 2005 Express Edition (VBEE) to carry out some processes. While away I built my user form, but when I got back I found that VBEE refuses to connect to SQL Server 2005 and is only configured to link to SQL Express.
The data source is set to .SQLEXPRESS in the advanced properties of the Add Connection form in the Data Source Configuration Wizard and you can not change it.
I read in MSDN ID 329721 that you can create a data layer that will allow you to use the wizards, but that is as far as it went and is above my programming skills.
So my only options are use VB.Net 2003 Standard edition, use connected mode or give up and it was only supposed to be a quick fix. Had anyone else had this same issue and developed a work around?

Hiya,
I'm a SQL n000b, and have just joined the forum 5 minutes ago seeking an answer to this problem that I've encountered. It seems that the way connection strings are handled in SQL 2005 have changed. This connection string used to work, but is now borked:
<add key="DBNAME.ConnectionString" value="packet size=4096;integrated security=SSPI;data source='sqlvirdev0035dev35';persist security info=False;initial catalog=DBNAME;connection timeout=60" />
Has something explicitly changed in SQL 2005 that would break this <add key>? Does something need to be set server side in order to handle these connection strings now? I have no idea why this won't work anymore, I just know that it doesn't work.
Ty for any help,
~Chipley

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
Microsoft OLE DB Provider for SQL Server (0x80004005)
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
do you know which provider can I use?
or maybe it is a sacurity problem

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
