I have a general question relating to SQL Express User Instances. Our application connects to a local SQL Express database through the default SQLEXPRESS user instance. My question is simply whether a user may experience a problem in connecting to our application's database should another application already be connected through the same default user instance (SQLEXPRESS)? The two applications are therefore running similtaneously. Also, are there any limit to how many applications could use the same service similtaneously?
When I am in Visual Studio 2005, and I try to add an SQL database, I get the following error "generating user instances in sql server is disabled. use sp_configure user instances enabled to generate user instances." I am currently using SQL server 2005 Express. What do I need to do, to create an SQL database? 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.
I would like to have more info on UserInstances concept of SQLExpress 2005.
Can i find any code samples for this feature in MSDN.
I have tried using the following links.. http://msdn2.microsoft.com/en-us/library/ms143401(SQL.90).aspx http://msdn2.microsoft.com/en-us/library/ms143684(SQL.90).aspx http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnsse/html/sqlexpuserinst.asp http://msdn2.microsoft.com/en-us/library/ms254504.aspx http://msdn2.microsoft.com/en-us/library/ms165690(SQL.90).aspx http://msdn2.microsoft.com/en-us/library/ms143446(SQL.90).aspx
any other links will be helpful for me in this regard.
But I'm not quite clear on what will happen if you currently have SQL Server Express 2005 installed with User Instances, and then you launch the installer for SP1.
Will it also update the User Instance? If so, how could I tell? When I go to the registry for the User Instance it has the older version value ie.
I have used SQL Server Management Studio Express (SSMSE) and Visual Basic 2005 Express (VBE) for more than one year to pick up the Transect-SQL, ADO.NET 2.0, SQL Server 2005 Express, SQLCLR, etc. Yesterday, I used SSEUtil to execute: C:SSEUtil>SSEUtil -l I got the following: 1. master 2. tempdb 3. model1 4. msdb 5. 56713D4D965AE4455_TSVISUAL STUDIO 2005PROJECTSMYFIRSTAPPSSE-VBEXPRESS-WINDOWSAPPLICATION1BINDEBUGMYDB1.MDF 6.

A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
I have been developing and testing my app for some time without worrying about the question of user instances. Due to the nature of the app, I would want the database to be copied to laptops, where data would be added and then merged back into the "main" DB.
To facilitate this, when the (VB) app first installs, it copies the DB files from the data directory to an easily accessible folder which it creates in the C: drive (if they are not already there - to facilitate application upgrades).
The code is written and working. However, then I thought about user instances. With User Instance set to True, I suspect that this concept of a DB file created by a user on a given machine being readable by another user with a laptop is likely to fail (unfortunately I only have access to a single machine).
So I tried to change the User Instance to false (in the App.config file). This stopped the application from running. I checked in the Modify Connection (Advanced) screen which still showed User Instance to be True. I tried to change this but got an error message.
I can see a way around this, but I don't like it. I guess, rather than "export" the DB files to the laptop, I could send the data as an XML file. However, this seems to me to compromise security as it would be very easy for anyone to filter any actual data they wanted from such a file - unless there is a way to password protect an XML file?
So, is there any way that I can make these DB files (on the C: drive) available to any user, on any machine who is running the application so that they can import the data to their version of the App, add to it and then send the changes back to the original?
So if the connection strings for say 2 separate users is configured for a user instance, what is the best approach to synchronising the user instances against each other and the Server instance?
This architecture suits remote users and I'm very interested to learn more about it.
On first run, my app takes the blank database from the data directory and sticks it into a folder on the C: drive. Lets call this folder ABC for convenience.
Now, sometimes, we need to take this DB to use on another machine. So I have a "Guest" button available at logon screen of the app that allows the user to browse the file system and select a different DB to use then creates the appropriate connection string for say, a DB on a USB stick or wherever.
Con = "Data Source=.SQLEXPRESS;AttachDbFilename="
Con += OpenFileDialog1.FileName
Con += ";Integrated Security=True;Connect Timeout=30" ';User Instance=True"
No problems here, it works for Express Edition.
However, someone else who is trying to use the app has SQL 2005 (not Express Edition installed) and it wouldn't work because the connection strings had User Instance = True in them.
Okay then, we'll just remove that bit of the connection string and it should work. They should be an Admin so no reason for User Instances.
It works fine if we browse to any DB file other than the one in ABC folder.
However, it is impossible to connect to the DB in ABC folder unless User Instance is set to True.
Secondly; for the app to work with the non-express version, would the connection string need to be changed (SQLEXPRESS)? If so, how do you detect programmatically which version the user has?
We have developed an application that uses User Instances of the database for each user. We have a stored proc that enables and disables the triggers on the various tables of the database. In our first round of debugging we have found that the applciation hangs when we try to either enable or disable the triggers. Can you modify triggers in user instances???
I couldn't reply the another thread so I'm continuing here.
Was about "Enable user SQL instances" and the Report Service didn€™t started too. How do I enable this remote connections? And in the instalation, Should I Add a user to the SQL Server Administration Role?
And also in the step "ready to install" of the SQL Server SP2 shows the following:
I nearly went nuts before finding out that SqlExpress Names Instances don't listen on Port 1433. Having discovered that I now think I can nominate a specific port, is that correct.?
My main question. I copied my databases from my development machine to a server, which will be accessed from an internal domain, and also through VPN tunnels. Should I change from User Instances on the server, and if so, how do I do this.?
My original application wasn't using User Instances, but chnaged to them somehow, when my PC had a name change.
I have recently returned to developing a website using Visual Web Developer Express 2008. I want to store information in a database. I have SQL Server 2005 Express edition installed on my pc. When I try to Add New Item -> SQL Database from VWD2008 by right clicking in the App-Data folder and completing the dialogue I get the following error message:
Generating user instances in SQL Server is disabled. Use sp_configure ‘user instances enabled' to generate user instances. I have SQL Server Management Studio installed but do not seem to be able to resolve this issue. My operating system is windows XP Home SP2. Some guidance on solving this would be appreciated. Many thanks Roger L
I just want to know if SSCE 3.0/3.5 can cater for Multi-user instances? I have a desktop application that I want to allow multiple Windows-user accounts to access. basically I need a datastore that can be lightweight (which SSCE is) and support "User Instances" (like in SQL Server Express)
I am attempting to restore a backup of a 2008 R2 database to my new 2012 instance. I am receiving the message, "FILESTREAM feature is not supported on user instances."Â I am running v11.0.5343.0 (X64), Express Edition.I was under the impression from the features supported page [URL] .... that FILESTREAM was supported across editions. I can't seem to find anything online specific to 2012 as to why I am not able to restore.
This is my first C# (2.0) Windows based app accessing a local SQL Server database. Ive build a couple of web based apps using C#.
First I just copied a datbase access wrapper class from one of my web apps and used that. It works, but, the database shown in Server Explorer in VS2005 shows the table as empty. The table in /bin/ however, is updated as expected. Before I realised that there were seperate instances of the database i stripped everything down to a very simple example
This little tester windows based app has a simple tester drag and dropped grid view in it. When i run /pathToApp/bin/Debug/<AppName>.exe, independantly of VS, the grid view is full of the value "atest" as expected, but not when ran under visual studio. As I said above i found (at least i think this is right) there is a debug and user instance of the database. So im guessing I need two connection strings if i want to update both whilst dev'ing the application.
Ive had a look throuhg connectionstring.com and, to be honest, im confused... Any help for what the second connection string should be would be greatly apprecaited.
Using SQL Express, UNDER COMPUTER management, SQL Server Configuraqtion Manager, SQL Server 2005 Network configuration Ihave the following listed instances
CSOLUTION - not listed under services
MSSQLSERVER - Disabled
SQLEXPRESS - Diaabled
SQLTEST - Disabled
SQLEXPRESSDATA - used by VB05 program
Questions
a) how do I delete all the instancces I do not use. In MSDE, each instance could be removed via the add/remove programs, but I don't see how to remove it under express
b) since SQLEXPRESS is the default for an SQL Express installation, I would like for the VBB05 program to use that instance; how do I do that?
I am developing an application that uses SQL Server Express. Everything is running great, except that I can't figure out how to copy a DataBase from my server at work onto my laptop so that I may test it at home...
How can I copy the DataBase from my Server at work to my laptop? I'm on the network at work, I just can't figure out how to copy it...
The disabled instances will not start due to various error messages.
Under Computer, Manager, Services, more instances are listsed, which also will not start:
SQLEXPRESSDATA for example (which is disabled)
I would like to remove CSOLUTION since it is not used; it will not remove from control panel or manually via http://support.microsoft.com/default.aspx/kb/909967 . You get various error messages, such as
Another application has exclusive access to the file c:program files...errorlog. Please shut down all other applications, then try again.
Even after a reboot, I still get this error.
I want to install and use instance SQLExpress, and I cannot remove it, but it will not start, and trying to reinstall it fails.
It was simple under MSDE 2000, no2 it seems to be impossible.
Does anyone have any ideas?
Honestly, I would like to uninstall SQL Express 2005 completely (except the BCM instant), and start over, but canot find a way to do this. SQL Express is a mess, I have spent days trying to resolve this, and am still where I started. Thanks, bob
I installed SQL Server Express trail for 3 times each with new instance. Now I came to know that I need to have a default instance. I un-installed the SQL Server Express and tried to install it again. It still says I have installed instances and if I select default instance the option buttons are un-checked and disabled. I tried to delete all the folders related to the SQL Server installationa dn tried but still I see the same thing. Please help me in istalling the default instance.
Just wondering. On some workstations and a couple of servers we have apps each running an instance of MSDE so these machines each have anywhere between 2 - 5 instances of MSDE each.
Would it be benificial from a resources point of view (not to mention a patching one) if we set up one instance of Express to replace the multiple MSDE ones?
My client has a server running MS 2003 Server for Smal Business Server, and it has SQL Server Express 2005 installed (I believe it is installed 3 times, as part of SharePoint, Veritas Backup Exec and ACT! applications).
I am trying to implement an application that uses SQL Server 2000, but the Server 2003 SBS does not support that version. So I need to launch an additional instance of SQL Server Exp 2005.
To do so, do I need to download and install SQL Server Express 2005 software again? Or can I just run SQLSVR.exe from an existing instance, but with a different instance name (sqlservr.exe -s<InstanceName>?
The reason I need another instance is that these existing instances limit DDL statements.
I am new to this and compare it to launching MS Word multiple times - you don't need to reinstall Word to run it multiple times.
Is launching from the command line a bad idea - and if it is, what is the better way to ensure that it launches under the local system context a service?
Thanks in advance for any help and insights. It is much appreciated.
This is probably easy for some who have done it, but I have an installed Instance of SQL Server 2008 Express or SQL Server 2008 R2 Express I'll call Instance CCC and need to remove it. Â I have two other Express instances I'll call Instance AAA and Instance BBB. Â I want to uninstall Instance CCC without affecting the other two instances or the software that uses them. Â Instance CCC should have been installed as a SQL Server 2012 Express instance, so I need to remove the 2008 Instance of CCC and reinstall it as 2012. Â In all cases, I'm talking about SQL Server Express. Â Full SQL Server is not installed. Â
The Instances are all installed on a Windows Server 2008 R2 Standard server. Â Â
I have read that I can do this through Control Panel  >  Programs and Features, but that I can corrupt or mess up the other instances (AAA and BBB) if I don't do it right.  I'm uneasy about this, not having done it before, and do not want to affect the users of the AAA and BBB instances! Â
We have 10+ MSDE 2000 installations on the same network. Each install has a named instance and the machines connect to eachother via VB application. We have a couple SQL 2000 Standard boxes and a SQL 2005 box all running on the same network with no issues. The problem we have recently run into is with a SQL Express box. When the box is on the network OSQL stops finding the MSDE 2000 named instances on the network and only the SQL Express named instance appears in the list. The second the SQL Express box is removed from the network the named instances are visible. I monitored the UDP traffic and suspect there is an issue with the response from SQL Express to OSQL. Can't find any issues for this problem only report I found is if MSDE and Express are on the same machine.

For the first time, I want to set up the configuration of my SQL Server Management Studio Express (SSMSE) to allow me in doing the non-User-Instance/ADO.NET 2.0 programming from my VB 2005 Express. The SSMSE and VB 2005 Express are in my Windows XP Pro PC that is part of our NT 4 LAN System in our office. I read the article "How to configure SQL Server 2005 to allow remotre connections" in http://support.microsoft.com/kb/914277/ about (i) "Enable remote connections for SQL Server 2005 Express", (ii) Enable the SQL Server Browser service", (iii) Create exception in Windows Firewall, and (iv) Create an exception for the SQL Server Browser service in Windows Firewall. I entered the SQL Server Surface Area Configuration and I could not decide what options I should take for doing the non-User-Instance/ADO.NET 2.0 programming from my VB 2005 Express. I have the following questions on the page of "Minimize SQL Server 2005 Surface Area": (1) I saw "Configure Surface Area for localhost [change computer]". I clicked on [change computer] and I saw the following: Select Computer The Surface Area Configuration of this surface area of this computer or a remote computer. Specify a computer to configure: O Local computer O Remote computer Should I choose the "Local computer" or the "Remote computer" option? (2) Below the "Configure Surface Area for localhost [change computer]", I clicked on "Surface Area Configuration for Service and Connections", Select a component and then configure its services and connections: |-| SQLEXPRESS |-| Database Engine Service I picked => Remote Connection On the right-hand side, there are: O Local connections only O Local and remorte connections O Using TCP/IP O Using named pipes only O Using both TCP/IP and named pipes Should I choose O Local and remorte connections and O Using named pipes only?
Please help and tell me what options I should choose in (1) and (2).
I had a server with SQL Server 7.0 I installed a named instance of SQL Server 2000 and then i passed all my DB of the 7.0 instance to the 2000 instance. Then i removed the 7.0 instance, that was the default instance. So at the moment there is only the 2000 version, but it isn't the default instance Can the 2000 instance become the default instance? (So that clients can connect to it simply through computer name, and not creating an alias)
I get an error dialog when I try to create a new SQL database, both via the Add New Item dialog and the property wizard of a new SqlDataSource control. The error is:
Local Database File:
User does not have permission to perform this action.
I've searched for help with this.
I ensured the App_Data folder exists and I added the local ASP.NET account to the group that have R/W access to it (although the RO flag is in an unchangeable tri-state on the folder). The SQL Server Express error log is clean and indicates full functionality. Everything is running locally. No VWD installation errors.
Okay, I've read massive topics on ClickOnce, and embedded database applications, etc, etc.
I need a handful of good suggestions how I can create a deployment package, to get my sql express database onto a SQL Express server.
The database will need to be multi-user, because I am also developing a WinForms application to connect to the SQL Express database.
I'm thinking I need to use some automated scripting features, to generate scripts for the database once I am done (unless you have a better suggestion).
After that, I need to know what to do with those scripts, and how can I create a setup / deployment packages to run those scripts against a SQL Express server.
The other alterntative obviously is to copy my sql express database, and run an attach command. This will work the first time, only because this will have been the first deployment of this database.
Please keep in mind when answering this question, that I will not be embedding the database, and as far as I understand ClickOnce is a feature for use with embedded databases or user instance databases (not sure).
Hi all, I have read/studied (i) Working with Databases in Visual Web Developer 2005 Express in http://quickstarts.asp.net/QuickStartv20/aspnet/doc/data/vwd.aspx, (ii) Xcopy Deployment (SQL Server Express) in http://msdn2.microsoft.com/en-us/library/ms165716.aspx, (iii) User Instances for Non-Administrators in http://msdn2.microsoft.com/en-us/library/ms143684.aspx, and (iv) Embedding SQL Server Server Express in Applications in http://msdn2.microsoft.com/en-us/library/ms165660.aspx. I do not understand the concepts and procedures to do Xcopy and User Instances for non-administrators completely-I do not know how to connect to databases and create database diagrams or schemas using the Database Explorer. I have a stand-alone Windows XP Pro PC. I have created a ChemDatabase with 3 dbo tables in the SQL Server Management Studio of my SQL Server Express and a website of my VWD Express application with an App_Data folder. I am not able to proceed to use Xcopy and user instance to bring the 3 dbo tables of ChemDatabase to my App_Data folder. Please help and give me some detailed procedures/instructions to bring the 3 dbo tables of ChemDatabase (or ChemDatabase itself) from the SQL Server Management Studio Express to the App_Data folder of the website of my VWD Express project? Thanks in advance, Scott Chang
