Changing ConnectionString Settings
Jun 5, 2006
Hello all. I created an app locally with VWD Express and moved it to to our server but I am getting the following error...
An attempt to attach an auto-named database for file D:WebApp_DataSurvey.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
This is the connectionstring from the web.config file used on the server. I did not change anything from the local copy.
<connectionStrings>
<add name="SurveyConnectionString1" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Survey.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
What settings do I need to change in order for this to work? Any advice is appreciated. Thanks.

Hello. What I'm trying to do should be fairly simple, but after an hour of searching and trials, I can't seem to get it working.When I run my website on my test machine, I would like it to use a certain value for my connectionString. But when it's run on the live server, it should use a different connection string. This way, when it's on the test server it'll use the test database.In my Web.Config file, I have this:<connectionStrings> <add name="myConnectionString" connectionString="Data Source=TEST_DB;Initial Catalog=tester;Integrated Security=True" providerName="System.Data.SqlClient" /></connectionStrings>I would like to be able to change the connectionString in something like the Global.asax file, when the application is loaded. I'd check for a certain environment variable, or some other condition, and change the value of the connectionString.I tried this in my Global.asax, but it told me the value was read_only: ConfigurationManager.ConnectionStrings["myConnectionString"].ConnectionString = "Data Source=LIVE_DB;Initial Catalog=live;Integrated Security=True" Does anyone have a good way of doing this, so I don't need to juggle Web.Config files when I publish my site? Thanks.

I have a package that I plan to run against about 700 databases to look for anomalies. I have several package variables in place that are passed in at runtime. One of them will hold the path and filename of the error log for the current database in process. I want each database to generate it's own error log for documentation and research purposes. However, when I run the package, it continues to use the path and filename that I entered when I created the File Connection Manager. I am trying to update that value in a Script Task by using the ConnectionManager class and setting the value for the "ConnectionString" property. This method is working for the OLEDB Connection Manager (which tells the package which Access database to process), but not for my File Connection Manager. Please help!

Hi,
I was wondering how to change the language settings on SQL Server. The server is currently set to US English, and I was wondering how it is possible to change it to UK English. The Server Regional Settings are set to UK English.
Also, on a semi-related topic, does SQL Server store dates in a universal format, and then when data is requested does it 'translate' these dates into the format required by that particular regional setting?
Thank you for any input
Marman

Hello all,
I have created a simple package that imports data from a flat file into a database. To run the package I'm using a SQL Server Agent Job. The location of the file is stored as a connection string in the Connection Managers tab in the SQL Server Agent Job.
Is there a way to change this connection string programmatically? If not programmatically, is there a way to change this setting right before I execute the package. I want to change the location of this file based on user input. Also, I'm executing the package using the sp_start_job stored procedure to run the job.
Thanks in advance for any advice!

Hi There
We currently have the following scenario:
4 app servers with regional date and time settings of locale A.
1 database server with locale settings B.
What is happening is that timestamps are being generated on the app servers, these are then in a sql command which fails on the database server since the timestamp format is invalid.
It was suggested that we change the regional locale settings of the database server, but will this not have serious implications , for example every current timestamp format in the datbase will become invalid?
In a nutshell is it safe to change a database servers regional date time locale settings ? Or are there serious implications?
Thanx

What different are there between connectionString (Part 1) and connectionString (Part 2) in web.config
The CCWW is my PC's name, normally I can connect to the database ASPNETDB.MDF correctly either Part 1 or Part 2 in a web page,After I open Database Explorer panel and browse ASPNETDB.MDF, I can't connect to database using Part 2 when I open a webpage in Microsoft Visual Web Developer 2005 Express Edition,but I can correctly open a webpage using Part 1 after I open Database Explorer panel.
What different are there between connectionString (Part 1) and connectionString (Part 2) in web.config?
I guess while I use Part 1 to connect, maybe it will be cancel exclusive method of the database ASPNETDB.MDF first, but when I connect to database using Part 2, maybe two programms both Part 2 and Database Explorer visit ASPNETDB.MDF at the same time!
--------------------------------------Part 1------------------------------------------------------------------------<add name="MyConnect" connectionString="Data Source=.SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|ASPNETDB.MDF" providerName="System.Data.SqlClient" /> --------------------------------------Part 1------------------------------------------------------------------------
--------------------------------------Part 2------------------------------------------------------------------------<add name="MyConnect" connectionString="Data Source=CCWWSQLEXPRESS;Initial Catalog=ASPNETDB.MDF;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|ASPNETDB.MDF" providerName="System.Data.SqlClient" />--------------------------------------Part 2------------------------------------------------------------------------

This works:
SqlDataSource1.ConnectionString = "Data Source=mydb.myserver.com;Initial Catalog=mydbname;User ID=mydblogin; pwd=mydbpassword";
This doesn't:
SqlDataSource1.ConnectionString = "<%$ ConnectionStrings:myConnectionString_from_WebConfig %>"
Ok, how do I tell it to use my connection string from my web.config?

<VS2005, SQL Everywhere CTP>
When I create typed datasets (for SQL Everywhere db) using the VS designer, I get a connectionString like Data Source =".App_DataDb1.sdf" added to the settings file by the designer. This works fine in the designer but not at runtime. If I replace the settings value to Data Source ="|DataDirectory|App_DataDb1.sdf" then it works fine at runtime but breaks the designer. I looked at the typed dataset designer generated code & it creates a SqlCeConnection object which supports |DataDirectory| macro. So, how can I get the designer & runtime to agree on a connectionString. I guess I can create a partial class for the table adapters & force a connectionString at runtime via a constructor overload, but, is that my only option?
Btw, the error I get at runtime when using the designer generated connectionString is:
"The path is not valid. Check the directory for the database."

hi,
I'm having this application using the express way to create the dategridview by having the query string builder. However, my computer recently crashed and I have no idea to change the connection string. so when I load the whole windows application, I am unable to view the information that are supposed to be in the datagridview. however, it returned an exception.
after finding out the main culprit, I realised that the database is using the old sql server's login. since it is using the old database's login, therefore it is unable to log the information into the datagrid view.
Please help! Thanks.

Hi all,
I want to connect to an SqlServer database and I have given the connectionstring on an WinXP computer as Dim ConnectionString As String = "server='localhost'; trusted_connection=true; Database='domains'"
Now, when I copied the files to another computer which is Win 2003 Server, I had to give the connectionstring as
Dim ConnectionString As String = "workstation id=INFO0;packet size=4096;integrated security=SSPI;data source=INFO0;persist security info=False;initial catalog=domains"
Now, I want to upload the files to a website called "BrowseNow.com".
What should be the connectionstring when the files are being uploaded to the server.
I want the public to read from and write to this database tables.
Is there anything I should do witht the SQL Server Enterprise Manager?
Thanking you in advance,

In short, I have a couple grid views on a page that are used for editing as well as sorting, etc. The grids are setup to use the SqlDataSources. I'm trying to deploy this to a server environment for different instances (test,cert,prod) and am trying to set the ConnectionString for the SqlDataSource in the code behind (Page_Load()). Everything works well, except, I get an error message that says the "ConnectionString Property Has Not Been Initialized." Its a javascript alert coming up on top of the grid view.
Here is how I'm trying to set the ConnString in the Page_Load():this.EmployeeTimeCardDataSource.ConnectionString = ConfigurationManager.ConnectionStrings[connStr].ConnectionString;
Here is an example of the DataSource.<asp:SqlDataSource ID="EmployeeTimeCardDataSource" runat="server" SelectCommand="sp_Select_Managers_Employees_List" SelectCommandType="StoredProcedure"> <SelectParameters> <asp:SessionParameter Name="CurrentUser" SessionField="User" Type="String" /> </SelectParameters></asp:SqlDataSource>

Hi all
This is the code in my web.config file.
<appSettings> <add key="ConnectionString" value="server=127.0.0.1;database=testdb;uid=sa;pwd=sa"/> </appSettings>
When I'm connecting to the sqlserver database,the page shows that The ConnectionString property has not been initialized.
The code that I used to get the "ConnectionString" as belows
using System.Configuration;
protected static string connectionString =ConfigurationSettings.AppSettings["ConnectionString"];
public static object GetSingle(string SQLString,params SqlParameter[] cmdParms) { using (SqlConnection connection = new SqlConnection(connectionString)) { using (SqlCommand cmd = new SqlCommand()) { try { PrepareCommand(cmd, connection, null,SQLString, cmdParms); object obj = cmd.ExecuteScalar(); cmd.Parameters.Clear(); if((Object.Equals(obj,null))||(Object.Equals(obj,System.DBNull.Value))) { return null; } else { return obj; } } catch(System.Data.SqlClient.SqlException e) { throw new Exception(e.Message); } } } }
These code works well on my machine.When running on my colleague's machine ,the page show that exception.
Any ideal?
