I have a data table I have adabted for my own use and want to add a row to the table. Can I do that with Visual Web developer Express?

This is just a simple datalist of names. firstname lastname. there are 18 of them and i want to add more names
I am sorry if this is the wrong forum for this question but I can not find better fit. I am using Visual Studio 2005 to write an asp.net web site which includes an SQL data base. In the databaseI have a table called 'ACCOUNTS' which has primary key column called 'ID' and a nvarchar column called 'Name'. I want the values in the 'Name' column to be unique in the table so that all accounts have unique names. I don't want to make the 'Name' column the primary key because I want people to be able to change the name of their account after it has been created. It seems to me there must be some way to add such a constraint to the table but I can find none. I have searched the documentation and seen loads of references to unique columns but I can't find any way to set a column to unique thru the IDE (or any other way). Can anyone help me? Thanks in advance for any help.
I'm trying to learn some VB programming with the VB 2005 Express Absolute Beginner Series video tutorials (which I think is great) and have come across a problem that I can't solve.
When I follow the instructions in Lesson 9 (Databinding Data to User Interface Controls) my application will display the data from the database correctly and I can edit it (and as long as the debugger is running the data remains changed). However, the changes won't propagate back to the database. I don't get any error messages but after I edit the data, save (with the save button on the BindingNavigator toolbar), and end debugging the data in my database remains unchanged. When I use a MessageBox to show how many rows where edited/updated in the
I get the correct number back. I'm sure the problem is not due to coding errors since I've also tried running the accompanying Lesson 9 project file that can be downloaded from MSDN and the problem persists.
I'm using Windows XP SP2, SQL Server 2005 Express Edition and VB 2005 Express Edition. I've tried installing SQL Server 2005 Express with a number of different settings, including default settings, but it doesn't make any difference.
Would greatly appreciate any feedback on this as I'm keen to resolve this problem so I can get on with the next tutorial lesson.
This problem only occurs after deployment, not when debugging. In the table I am having a problem with I have an ID field designated as the primary key with the identity increment set to 1 and the identity seed set to 1. There is no data in the table when deployed. I can add records to the datagridview control but when I try updating the dataset I get this error indicating that the ID field already has a value of 1 present. If I close the application and re-start it, the exception no longer occurrs when I update the dataset. I am including the code to update the tables incase something is wrong there. Any suggestions?

I am using MS visual web developer and i get a lot of things but one thing i do not get is why is it when i set up the web.config to a data base i made on my own and run the website and create an account it creates a new data base and creates that new account in that new database, i've never opened the web admin tools. <connectionString> <add name="LoginConnection" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename="C:Visual Studio 2005WebSitesWebSite1App_DataYourEstate.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True" providerName="System.Data.SqlClient" /> </connectionStrings>
I need someone to give me a small briefieng on how a enterprise data warehouse (EDW)differs from a regular database? Currently we have an appplication that accesses a database with about 18 tables. We also have a Data Warehouse. For some reason I was thinking that it would be possibly to migrate thedatabase into the data warehouse. The reason is that in looking at the schematic design forthe data warehouse there are some data tables that could also be used by our application that uses the DB. I guess I am confused because I am not sure if a data warehouse is used in the same wayas a database?

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
SQLExpress database file auto-creation error:The connection string specifies a local Sql Server Express instance using a database location within the applications App_Data directory. The provider attempted to automatically create the application services database because the provider determined that the database does not exist. The following configuration requirements are necessary to successfully check for existence of the application services database and automatically create the application services database: If the applications App_Data directory does not already exist, the web server account must have read and write access to the applications directory. This is necessary because the web server account will automatically create the App_Data directory if it does not already exist. If the applications App_Data directory already exists, the web server account only requires read and write access to the applications App_Data directory. This is necessary because the web server account will attempt to verify that the Sql Server Express database already exists within the applications App_Data directory. Revoking read access on the App_Data directory from the web server account will prevent the provider from correctly determining if the Sql Server Express database already exists. This will cause an error when the provider attempts to create a duplicate of an already existing database. Write access is required because the web server accounts credentials are used when creating the new database. Sql Server Express must be installed on the machine. The process identity for the web server account must have a local user profile. See the readme document for details on how to create a local user profile for both machine and domain accounts.

Right Now I created bunch of reports based on the data base which is in my local machine. But now How can I connect those reports to data base in prodcution server?

And other option is moving ReportserverDB and TemperoryDB to production server environment. How can we do that? My supervisors dont like juct backing up and resotring option.
